3D Digital Projection in Indian Cinema:

One often quoted advantage of making one’s film in 3D is that “2D contents can be pirated … 3D cannot be!”

This adage is true to the extent that even if the best ‘camera print (sic)’ of a film’s theatrical release find its way to the illegal CD/DVD circuits, people would still have to go to Cinema theaters to get a good 3D film experience. Yet, this shall prove false in Indian Cinema in the near future. Providers of Film Content Encoding for theaters are jumping into the 3D bandwagon with unacceptable image compression and zero security features. It is not just that they compromise on quality … they put the creativity of the filmmakers open to piracy says Jijo, Director Chota Chetan.

He adds that Devoid of a proper HDCP in the MPEG picture stream played out from the operators cinema server, anybody in the projection cabin can record Stereo Image Pairs (which makes the 3D picture) onto two low-cost consumer camcorders with HDMI input. A teenager with basic computer skills can convert this file/s for BlueRay DVD or for the now exploding 3D ready TV market. Thus, once ‘filmgoers’ start seeing brand new 3D films within the comforts of their homes, filmmakers would realize that the old adage is no more valid

With more & more cinema screens across india converting to digital cinema projection, all is not well with projection quality of secondary projection system practiced in india called E-Cinema, which projects in resolution of 1K (1280x720p) or 1080p (1920x1080p) with mpeg-2(QUBE) or mpeg-4(UFO)format, where as DCI(Digital Cinema Initiative) suggests projecting cinema digitally @ 2K (2048×1080) in 24 or 48fps in Jpeg2000 format called as D-Cinema. For both 2D/3D.

With cost of of D-Cinema coming down and more films from Hollywood releasing in 3D only in D-Cinema, adaption rate is faster for D-Cinema even in smaller towns. But E-Cinema spread across india in last 5years with more than 5000 screens for 2D and they are coming out with E-Cinema 3d to theaters with less cost involvement for theatre owners.

For last 1 year with more and more films especially Hollywood films releasing in 3D, which supports D-Cinema only, Indian 3D films and Independent(Non Studio) hollywood films start supporting e-cinema 3d which makes two companies aggressively promoting e-cinema 3d in India.

Qube’s E-Cinema 3D, which runs @ 48 FPS 1920×1080 MPEG-2 at 120 Mbps, where left & right eye is individually watermarked and each output has HDCP with projector locking for twin projectors.

UFO’s E-Cinema 3D, does side-by-side Left & Right eyes within one 1920×1080 frame @ MPEG-4, roughly @ 8 Mbps. The output goes to a 3D processor (splitter) to separate into two outputs for twin projectors.

In December 2010, ‘My Dear Kuttichattan – special edition’ (Tamil) released across Tamil Nadu with more than 55 Screens in e-cinema 3D projection system provided by QUBE Digital Cinema Company using twin 1080p Projectors & Silver Screen. Same film being released in Malayalam using QUBE E-Cinema 3D across Kerala in September 2011.

Recently was asked to evaluate UFO E-Cinema 3D by UFO Moviez for release in Kerala for the above said film for e-cinema projection.

First and foremost when I saw their output in their chennai office, Asked few questions about the security of content, since they use splitter to project both left & right eyes to twin projectors, technicians there don’t have any idea about the technology used and asked to come back later and they never come back.

Issues with UFO E-Cinema 3D are as follows at present (since it’s in R&D and not out fully)

Splitter to split images without any security (they call it as 3D processor)
Visible Watermarking on one eye
Stretching the movie which was encoded to fit both left & right eye in single 1080p frame, which is similar to what Samsung, LG or Sony 3DTV use to play 3D content in the 3DTelevision, which looses resolution for bigger screen and long throw projections.

With above all, I believe they don’t even use any security for existing 2D films too with clear visible watermarking system.

Issues with E-Cinema 3D systems in general

Cost can’t dictate quality, which is at present in India.
Image compressions used in current e-cinema systems needs to be improved. My suggestion is to use same compression used in D-cinema which is Jpeg2000 with current e- cinema resolution of 1K or 1080p.
Filmmakers need to be consider at every aspect, there is common issue by DOPs over the quality of e-cinema system across india.
Filmmakers put 2 to 3 times more money & effort than 2D for creating 3D films and their consideration is utmost priority for 3D release, which includes consistent checking of 3D projection and handling of 3D polarized glasses

I believe there needs to be robust, secure, resolution and experience for digital cinema projection in theaters which will only can separate 1080p HD channels on DTH platforms & Cinema theaters, else the battle is on for TV vs Web rather than Cinema Theaters.

I’m not against E-Cinema rather, when hearing complains from DOP’s across India about bad digital cinema projection which they can do much about this in release times left with no options, I try to remind them it’s not D-Cinema and its only e-cinema which we create for our own convenience & cost leads to that which they are not ready to listen and complaint about the entire digital cinema projection.

Note: This blog post is no way to support or against any company and the issues regarding quality vs resolution vs security of content for filmmakers are utmost important and also for future of experiencing cinema in theaters rather than in TV via DTH, Youtube & Vimeo.

Arri Alexa – Final Cut Pro Workflow

Via Abel Cine,

ARRI’s ALEXA camera offers several recording options, including recording directly to SxS cards in Apple ProRes format. This is called the Direct-To-Edit (DTE) option, and it makes for a very simple workflow. ProRes has proven to be a high quality and robust video format that is widely used in the industry today. The ALEXA has an uncompressed video output, but I believe many productions will choose to record in ProRes directly in the camera. Here is a 3 step guide for how to import ALEXA footage into Final Cut Pro.

1. Insert your SxS card into your MacBook Pro’s ExpressCard34 slot. If you have a computer without an ExpressCard reader, then use the Sony SBAC-US10 SxS Memory Card Reader. The card will show up in your finder as ARRI UDF. UDF stands for Universal Disk Format, which is an open file system.

2. Copy your footage onto a hard disk (preferably a redundant array). The files are named with Camera Name, Reel, Scene and Take numbers. Make sure to copy all clips AND the index.xml file. I recommend making a separate folder for each card copied.

3. Import the index.xml file into Final Cut Pro. Use the File -> Import -> XML function to do this.

Final Cut will pop up a dialog asking for some information. Set your destination to whatever your project name is (my project is called “Alexa”) and click OK.

Now all of your clips should appear in the bin. Notice they are under a folder named after the Camera Name and Reel info.

Repeat Step 3 for each card and you should have all of your footage imported in no time. Now you can start editing!

Shooting on the 5DmkII for LUCASFILM

I get asked this the most. Apart from which lenses should I buy. There is a lot of confusion amongst potential buyers as to which camera to buy. Not just from the Canon line, that is the Rebel T2i/ 55D, 7D, 5DmkII and 1DmkIV but also the GH1 and the Nikon D300S , D3s, D90 and D5000.

It’s almost impossible for me to recommend which model camera to buy because they all have their plusses and minuses and many of those are subjective, down to personal opinion. What may be important to me may not be important to you. Even when context is provided such as they are mostly shooting music videos, events, documentaries, movies etc then I still cannot answer.

We already put these cameras through the big test for Zacuto…but what about actual every day use…?

What I am going to do in this blog post is list what I believe are the pros and cons of each camera.Take that info and then decide for yourself what is the most important for you. For example some people love the look of the 5DmkII over the others whilst others find the shallow depth of field too much…

I am in the fortunate position of owning most of the cameras in this post (apart from two of the Nikons) so I feel quite qualified to give my opinion on this topic!

Here is a sensor chart showing you the different sizes available in the market. I will be referring to this a few times in the blog.

Nikon D3s

First off let us go over the non Canon options as that’s easier.  I have to say unless you have an huge array of G series Nikon lenses (if you have manual aperture Nikon lenses then your lenses will work will the Canons using a simple adaptor like the Fotodiox Pro) then forget the D90, D5000 and D300s as they don’t offer full manual control in video mode making them a huge pain in the backside to shoot with. The only Nikon that offers full manual control is the D3s. To get the full manual mode you need to be in tripod live view mode rather than hand held live view mode.

What do I think of the D3s? It is an incredible stills camera and a so-so video camera. It has a full frame sensor, one of only two cameras in this blog to have that. The thing that made me buy it was the absolutely incredible low light performance as highlighted in the Zacuto Shootout. It was this alone that made me buy it. In my low light test I shot at 25,000 ISO and got incredibly clean pictures due to a brilliant NR chip in there for video. This makes it outperform all the Canon DSLRs by a huge margin in low light. It’s just a shame that it is not as impressive in general use. All the Nikons are 720p 24p only too. That is not a huge dealbreaker but it’s a limitation. As is the old fashioned MJPEG recording format and 5 minute clip length. The HDMI live out seems to be slower than 24p when you hit record.

I bought this camera as a low light tool to supplement my Canon DSLRs, not to shoot whole projects on. For some of my documentary work low light will be extreme and this camera will shine. I will be able to shoot in very low light without having to shoot wide open with crazy shallow DOF. To think I could shoot in candlelight at F4 and it will look gorgeous…That’s epic for me. Shooting wide open is great but sometimes you don’t want that crazy shallow DOF, you want to control it. This camera will give you that option. You can stop right down and with the incredible high ISO you can shoot in not much light and still get exposure!

Sound wise it has a crappy built in mic like most of the cameras here but you can put an external mic in, but like most you have no control of the audio or any way to monitor it.

So that’s the Nikon D3s. A great stills camera with a killer low light video ability. Shame the rest is not great.

PROS: Full frame, INCREDIBLE low light in video

CONS: Expensive, 720p only, 24p only, 5 minute clips, MJPEG recording format, poor monitor out, no audio control.

Pansonic GH1

The Panasonic GH1 I have had since April last year and I still love it. It’s not a DSLR as it has no mirror but is often bunched up in the term Video DSLRs as it is a still camera with a video function too. We really should not get hung up on names for these cameras.

What do I think of the GH1? Well I love the small size. Love the EVF, moveable LCD, ability to take so many different types of lenses due to the lack of mirror and of course the price. Downside is the 1080p bit rate if a bit stingy meaning it breaks ups quite easily when trying to grade it. The 720p mode seems to hold up better but it’s such a shame that the 1080p is lacking. The 720p mode is 50p or 60p depending on where you buy the camera.

The camera comes in different flavours depending on where you buy it. In the EU it is 25p in 1080p mode (embedded in a 1080i stream) and 50p in 720p mode, so great for slow motion. Record time is limited to 29.59 minutes for EU tax reasons. If it could record 30 minutes or more it would be classified as a video camera and therefore have higher tax. Other PAL countries get this camera also in 25p but with the record time limitation. The US gets it in 24p (again embedded in a 60i stream) and 60p in 720p mode with no record time limitations. All the Canon cameras shoot in either 24p, 25p or 30p. They are non regional specific. A big downer on these cameras.

It has the best built in mic on all of the cameras and it’s stereo, although again we have no headphone jack. NONE of the cameras in this test have a headphone jack! If you plug in a monitor it switches off when you hit record. A big downer really! That needs to be fixed in the GH2.

Negatives aside. It’s a great little camera. The stock lens has the most impressive auto focus I have ever seen on a video camera as it tracks people’s faces and with a large sensor like in this camera (four thirds) it makes a huge difference. This makes it ideal for steadicam work as you can let the focus do it’s thing. Normally I say DO NOT USE AUTO FOCUS on any video camera. Manual will always be the way to operate a camera for me until it can read my mind and know what I want to be in focus! The image out of the camera is also pretty damn good. Of course what I want is a GH2 with better bit rate and proper monitor out, a headphone jack and controllable audio levels. A lot of this camera is already very good, it just needs a bump up in specs…

Low light is not brilliant. I find 1600 ISO way too noisy.

PROS: Cheap, light, small, 50p/60p mode in 720p, full HD, nice stereo mic, EVF, articulated LCD, great lens mount, some Panasonic lenses have amazing auto focus ability.

CONS: Weak AVCHD code, no HDMI out when recording, poor audio options again, recording limitations in EU,  geographically locked recording formats.

Canon Rebel T2i/ 550d

The new kid on the block and a damn impressive one too. I have left the 500D/ T1i out of this. Even though I own it due to the odd 20FPS 1080p mode and lack of manual control. This baby ups the game and is the first consumer DSLR that Canon have made with full HD and full manual control. It’s killer. With an image of almost comparable quality to the pro 7D it has taken the market by storm and rightly so.

With an APS-C chip in it which is a 1.6x crop of a full frame it has a bigger sensor than the GH1 but smaller than the D3s. It takes all the EF lenses designed for full frame cameras as well as the special EF-S lenses which are designed for this sized chip. These lenses are generally cheaper than their full frame versions so you can save money that way. Only downside is EF-S lenses cannot be used on full frame camera if you come to upgrade cameras at some point. The major investment with any of these camera is the glass, not the body. So always keep that in mind when buying lenses.

It has the same crappy audio options, as in no control and no headphone jack. But does have the full range of recording options. 24p, 25p and 30p in full HD and 50p and 60p in 720p mode. Meaning you get shoot great slow motion with this baby.

I am a big fan of this camera as it has brought the power of DSLR filmmaking to the mass market. Some people see this as a bad thing, in that by making the cameras so affordable there will a flood of people on the market selling themselves as cameramen. It’s only a tool, like any camera. What we will have is people discovering or even re-discovering a love of video due to this large sensor.

Things I don’t like about this camera? Well it’s a consumer camera and is therefore missing a lot of what I love in the PRO bodies. It uses SDHC cards, they are cheap are small but I hate their flimsiness. I much prefer CF cards, but that’s just me! I miss the top LCD. We have no display on this camera other than the main LCD. Not a deal breaker but a shame not to have it. Also missing is the second dial on the back of the body which means aperture and shutter speed are controlled by the same dial, via pressing a button in at the same time. I don’t like this at all. The build quality is pretty good, but when compared to the pro line, in particular the 7D it comes across as bit cheap, but then again it is! It uses different batteries to the 7D and 5Dmkii, but they are cheaper…HDMI out sucks too….it’s 1080i letterboxed image live out which drops to 480p when you hit record. You do get full 16×9 playback though.

Like all the Canon cameras the most you can record at a time is about 12 minutes. If you point at something that does not move much you can get it up to 14 minutes or so. The LCD is surprisingly the best of the bunch of all the Canon DSLRs. Highest resolution.

There is much debate over how good the video is of this camera compared to the 7D. Very damn close. I haven’t seen any specific side by sides, only that in my limited use of the T2i it just seems to be not quite as good as the 7D and am not sure why…it’s close. But just not quite as good…I would love someone to show me what it is that is different!

PROS: Cracking image in video mode, very cheap, smaller than the pro line, full list of video modes to record in, nice big APS-C sensor, great LCD screen

CONS: Not weatherproofed like the pro line, missing top LCD screen, missing second dial, poor HDMI out, no audio control, no headphone jack, no intermediate ISOs, no ability to dial in your white balance like the pro line, 12 minute record limit.




Canon 7D

The first Canon camera to embrace the video feature as it has a switch to set it in video mode or stills mode!

It’s got the same sized chip in it as the 550D/ T2i albeit in a MUCH more robust package. The 7D is a beast. It’s completely weathersealed. I have left this camera outside for 4 days in snow and rain doing timelapses and it has come through without a glitch. This is for me what sets it apart from it’s cheaper brother. The build quality is simply superb.

Video feature wise it’s the same…24p, 25p, 30p in 1080p mode and 50p 60p in 720p mode. It can also rattle of about 8 or 9 pictures a second in stills mode. Very impressive. It has the same audio limitations that we run into again and again. No manual audio controls and no headphone jack.

The image out of it is superb. It’s sensor is almost the same sized as the sensor in 35mm movie cameras meaning with a mod or two it can take proper cinema lenses. A massive plus in the indie movie world and of course in the big movie world! I have used it with Cinema lenses three times now and it’s simply incredible!

The live HDMI out is the best of the cameras so far. Still letterboxed 1080i but it stays like this even when you hit record. This is a big deal and something you must consider when looking at the different cameras to buy. Getting critical focus when the image drops to SD when you hit record is very very hard!

Some people say it overheats a lot, something people say happens with their 550D too. But I have not experienced this much. Although I do live in a bloody cold country! I did experience it when I was doing very long interviews for 2 hours or so of non stop recording, but even then it was just a warning light. It never switched off.

Low light ability seems to be about the same as the T2i but not a patch on the D3s

PROS: Superb weatherproofing, stunning image, good in low light, switch for video mode, HD monitoring even when recording, Nice LCD screen, great price.

CONS: Not as good as the other pro Canon line in low light, not full frame, crappy audio options AGAIN, 12 minute record limit



Canon 5DmkII

This was the one that started it all and is still for me the camera with the nicest image. That comes down to it’s full frame goodness and full HD. The 5DmkII is absolutely unique in the video world as it is the only video camera in the world, currently, that shoots video in full HD with a sensor as big as this. Now this does cause us some issues. Some people find that the full frame sensor makes it harder to get focus, as the larger the sensor the more shallow the depth of field. For me, I always say if it’s too shallow then stop down! It has great low light, better than the 7d but nowhere near as good as the D3s, so you can easily stop down and up the ISO to compensate…It’s aesthetically unique and that is what attracts so many filmmakers to it, including me, there is nothing else out there like this. The 7D has better options…the 5Dmkii has no 720p mode, has the same crappy hit record and drop to SD mode HDMI out, no dedicated video button. It does have manual audio levels which have been pointlessly hidden away in a menu that you can only set before you hit record and give you no audio levels on the LCD at all so there is still no way of knowing if you have are recording sound or not.

It’s highly unlikely we will ever see this camera get 50p and 60p. I simply think it cannot take it…It would overheat too much…talking of overheating, this camera has no warning light telling you it is overheating. What can happen, and I stress CAN, is the image can degrade the more heated up it gets. Then it will just switch off.

PROS: My favourite image out of them all, full frame beauty, manual audio levels, very good in low light, great build quality, you can get this camera for not that much more than the 7D if you shop around, did I say incredible full frame image godliness?

CONS: HDMI live out sucks, manual audio buried away in menus, no 720p mode, no overheating warning, DOF too shallow for some (although as I say just stop down!), 12 minute record limit, not as good weatherproofing as other pro Canon cameras, probably the most susceptible to rolling shutter issues of the pro Canons.

Canon 1DmkIV

The big daddy of the Canon line. This is first and foremost a stills sports shooters camera. The video is hidden away and is obviously secondary BUT must not be overlooked as it betters the other Canon cameras in it’s low light ability. It has a strange sized APS-H chip which is a 1.3x crop. This is a bit annoying for wide angles as there are no lenses made for this chip size so you will lose some length on the wide end.

The low light as I said is very powerful, again, not a patch on the DS3 but very impressive anyway. 3200 ISO is pretty clean, 6400 ISO is usable with a bit of post cleaning up.

It has the same video options as the 7D so we do have 720p 50p and 60p and we also have the same HD monitoring out even when recording. Audio of course still sucks with no manual audio level and of course no headphone jack.

The camera is built like a tank. It make the build quality of the 7D look like the T2i and that is saying something. This is one camera that can probably take some serious knocks and keep on going. It takes both CF cards and those flimsy SDHC cards. It also takes it’s own special batteries which make it last a lot longer in video mode. The batteries in the 7D and 5DmkII get eaten up very fast!

PROS: Incredible build quality, beautiful image, superb low light, great long life batteries, probably the best of the bunch for least rolling shutter issues.

CONS: Awkward 1.3x crop, heavy, expensive, crappy audio, 12 minute time limit.

In conclusion…

Is that helpful? I hope so. As I said, there is no one clear favourite…I prefer the full frame image out of the 5DmkII for sure, but the HDMI out is killing me, on a professional set it is just a big problem. Also it doesn’t have the 720p mode that all the other Canon cameras have. Although the 720p mode is not great due to the hideous aliasing and moire that it can bring up if not careful.

The 7D is probably the best all rounder. Has all the video rates your want, HDMI HD monitoring and is a great price. Many prefer the aesthetics of the 7D over the 5DmkII, me I don’t but it simply comes down to personal preference. It has best build quality for the money, great image…but I just prefer the 5DmkII image…it probably ticks more boxes than the rest. Please don’t put weatherproofing as not that important. Being from the video world where nothing is weatherproofed, it’s so exciting to use these cameras in appalling conditions and not worry about them!

Of course one thing that also holds people back is the worry that a replacement will come out for one of these making their camera obsolete. Well, that is a danger with everything in life! That is why your main investment is in the glass, not the body. Your lenses will last 20 years! Your bodies you will change every 2/3 years. That’s the market!

Sony will soon jump on the bandwagon with the Alpha range. Be very interested to see what they are bringing to the table. I have heard a couple of interesting rumours. I wonder if they are true? The Sony NEX 5 and 3 are coming out soon and are very cute but lack manual controls in video mode and are only 30p…

Whichever camera you chose, don’t forget…it’s only a tool! The most important thing is what you do with it!

Note: Based on the above article and user of Canon 7D & 5D mark II and after seeing the footages of all the mentioned cameras, the real winner is Canon 5D mark II with full frame 35mm type sensor and future proof EF lens  mount.

The Great Camera Shootout 2010

Believe it or not future is Digital Cinema.

The Great Camera Shootout 2010:

Believe it or not, with the launch of Canon 5D mark II way back year and half back, there is only one camera which can record 2K images and you can carry the camera in your hand anywhere you want and to shoot anyplace you want. But all changed with the successive launch of Canon 5D mark II(Initially 30p and later 23.98p), Canon 7D (23.98p @ 1080p & 60p @ 720p) and Canon 1D mark IV (ISO 6400 with less grain).

With support from Vincent Laforte, Philip Bloom and Stu Maschwitz on web with their successive videos in a professional level which were then shown on their respective blogs and recent development of Canon & Vimeo partnered for contest with starting mobizode shot by Vincent, Canon sell cameras like hot cake. Then comes the accessory manufacturers like Red Rock Micro, Zacuto, Marshall electronics who started creating cinema style accessories for Canon HDDSLR cameras got bigger. The biggest of all comes NAB 2010 where there is talk or demo on every booth either about 5D or 3D(S3D).

Then comes The Great Camera Shootout 2010 done in partnership with Zacuto and industry leading DPs.

The above test where done in comparison with Kodak and Fuji Stocks, Canon 5D mark II, 7D, 1D mark IV, Panasonic GH1 and Nikon D3S.

NAB 2010 Wrapup

NAB 2010 wrap-up. (Via Scott Simmons for Studio Daily blog)

Winners

Adobe – everywhere you went people were talking about CS5. It was partly because this is a big 64-bit update but partly because Adobe has packed the release with some jaw-dropping features that make a demo. Premiere’s Mercury Playback Engine, After Effect’s RotoBrush and Photoshop’s Content Aware Fill together made Adobe the topic of NAB among post-professionals.

Avid – like Adobe, Avid got a lot of good buzz with the introduction of good product. Even Final Cut Pro only editors were talking about Media Composer 5, it’s native support of all QuickTime formats and the new “drag and drop” timeline. Add 3rd party hardware support and the web-based editing demo and Avid had one of their best NABs in a long time.

3D – It was everywhere with baskets full of 3D glasses at what seemed like most every demo booth. There were hardware and software tools abound to support stereoscopic production and post. And it was a common question at many a vendor’s booth: “Do you do 3D?”

ProRes – The announcement that the new Arri Alexa camera could deliver a native ProRes file started the ProRes win but the Avid QuickTime AMA support in Media Composer 5 continued it. Pretty much every Avid demo you saw mentioned QuickTime AMA support of Apple ProRes as a signature feature. And the AJA KiPro (while introduced at last year’s NAB) still generated it’s share of discussion partly because of that ProRes support.

Canon’s DSLRs – They weren’t just at every booth, atop every tripod, steadicam or crane, or surrounded by vendor after vendor’s support gear but also in the hands of seemingly everyone shooting and covering NAB. This was the year that P2 cards and XDCAM disks were out and CF cards were in.

Mac OS – Smoke on Mac, DaVinci Resolve on Mac, demos on Mac … Apple may be busy with iPads but the post-production community is still busy with Macs. While the Mac OS’s Linux underpinnings probably made it easier to port Smoke and Resolve to Mac it was the ever present Macs on the South Hall show floor that let you know Macs are clearly the platform of choice for post. I hope Apple still notices.

DaVinci – The industry standard in realtime color grading hardware was once expensive to buy and expensive to support. The company had fallen on some tough times and were bought by Blackmagic Design. The marriage had been a bit silent until the bombshell was dropped that the flagship (and six figure) Resolve product would now start at $995. That was big news.

Losers

Apple – Sure there was still Final Cut Pro and Macintosh computers all over the show floor (and ProRes as a winner) but FCP really looked long in the tooth and badly in need of a modern update after watching those Avid and Adobe demos. Add to this the (silly) rumor of an offsite Apple announcement on the Wednesday of the show and their silence was deafening … and easily ignored. Silly rumor is almost an understatement. The whole thing smelled more of desperation from Mac rumor sites to have something happen from Apple at this NAB. Just look over this posting and you can see the direction they took it. To add insult to injury the FCP product manager began his SuperMeet presentation with the words “I have a secret to tell.” He then went on to tell no secret at all. It was a groan-producing moment after great presentations by Adobe and Avid at the Final Cut Pro User Group SuperMeet.

Canon as a whole – What if you were a company that had produced one of the most popular, paradigm shifting cameras of all time? What if everyone expected a video professional version of that camera as an encore and it never came to be? What if you introduced a couple of new professional video cameras and nobody cared?

FilmLight – Speaking of nobody caring … what if you introduced a new entry-level price for your Baselight color grading system and nobody noticed? When $95,000 is that entry-level price it may be that nobody cared in the wake of the DaVinci price drop. It’s probably unfair to say that nobody cared but since they weren’t on the show floor (instead showing product at a nearby hotel) out of sight meant out of mind as I only heard about the Baselight price change until after the show.

Film itself – Aside from a film scanner or two there wasn’t all that much to see of real celluloid on the 2010 NAB floor. I was talking with a Evertz engineer (Evertz are the guys who’s name is often synonymous with film and Keycode) and he said this is the first year Evertz didn’t bring a single piece of film-related gear to the NAB show.

Blackmagic Design – Okay, the reintroduction of DaVinci with an affordable Resolve was a clear winner for Blackmagic but their other big development seemed to be support of the new USB 3.0 standard. While interest was good in the products that interest was often followed by the realization that Macs don’t natively support 3.0. At least not yet. Maybe Blackmagic knows something we don’t.

AJA – last year at NAB the buzz was all about the AJA Ki Pro. You were hard pressed to even push you way into the AJA booth to get a demo. While they had a nice, big booth again this year, without any major new products to announce not many folks were talking about AJA this year. And if they were it was usually about last year’s Ki Pro. I guess you can’t have a blowout show every year.

Panasonic – While the GH1 DSLR underwhelmed, Panasonic’s new AG-AF100 was being shown under glass and includes the GH1’s Micro Four-Thirds sensor in a proper camera body. Tthe excitement of the camera was often tempered with the discovery of the lower bit rate codec. Same with the 3D ready AG-3DA1. That camera looks like the venerable (and affordable) HVX200 with two lenses but the $21,000 price was what many came away from that camera with. 3D acquisition isn’t cheap!

RED – RED once again didn’t show on the NAB floor, instead opting for a user event, on Wednesday of NAB, at a neighboring hotel. There probably wasn’t as much discussion this year as last about them not being on the show floor but truthfully there probably wasn’t as much RED discussion overall since everyone was shooting Canon DSLRs and talking about the Arri Alexa camera. And there were no Scarlets to been seen. Why is RED a push and not a loser? RED was really pimping the EPIC camera, even having a working prototype at the REDuser event, and those RED users who were able to get up close were very impressed, talking a lot about the camera’s size and modular design. And those I talked to weren’t just fanboys but rather serious camera owners who are looking for the best tool for the job. When it finally ships it might just be its own revolution.

Panasonic 3D Camera, 3D Monitor & 3D Mixer

Panasonic 3D 2010

Panasonic’s push into 3D just took another step forward. Recently, they made several announcements about their 3D product lineup including details on their 3D camera (AG-3DA), a new 3D production monitor (BT-3DL2550) and a new 3D mixer (AG-HMX100). Panasonic is moving to bring 3D to a broad community of filmmakers and these new tools certainly show their commitment. We can’t wait to see all of these new products at NAB 2010. Learn more about these new devices after the break.

AG-3DA1

AG-3DA1

Panasonic’s integrated 3D camera is officially called the AG-3DA1, though I’m quite sure it will just be called Panasonic’s 3D cam for sometime. We first heard about this camera at last year’s NAB, but now we are finally getting more details. Here are the specs:

  • Twin lens system
  • Two 1920×1080 2.07 Megapixel 3-MOS sensors
  • 1080 60i, 50i, 30p, 25, and 24P (native) recording
  • 720 60P, 50P recording
  • AVCHD recording format
  • Dual SD/SDHC memory slots
  • 2x 32GB cards give you 180 minutes in AVCHD PH (highest quality) mode
  • Dual HD-SDI output
  • HDMI (version 1.4) output
  • 2 XLR audio inputs
  • Built-in microphone
  • Includes lens remote
  • Weighs less than 6.6 pounds

The twin-lens system allows the convergence point to be adjusted by an operator. The camera also has automatic horizontal and vertical displacement built-in, which eliminates some of the headaches associated with traditional 3D video processing. We have not yet seen this system in action, but it sounds like they are trying to make the system as easy to use as possible.

The resolution of the camera sensors is excellent, though there is no mention of sensor size in the announcement. The form-factor of the camera points to 1/3″, which is a good thing in 3D because of the increased depth-of-field. The dual HD-SDI outputs on the camera is exciting news. Not only does the camera offer AVCHD recording, but with uncompressed outputs it can be combined with external recorders such as the Panasonic HPG20.

The camera will be available this Fall for a list price of $21,000, and $1,000 pre-orders are now open as well. Read the full press release here.

BT-3DL2550

BT-3DL2550To capture 3D video you really need a 3D monitor to view it on. Up to now there has only been a handful of consumer 3D LCDs available, which aren’t exactly built for field production, but thankfully Panasonic has announced a 3D production monitor as well. The BT-3DL2550 is an updated version of their 25″ production monitor with support for 3D input. It features two HD-SDI inputs, and a DVI-D input for displaying 3D images. The two HD/SD-SDI inputs can simultaneously display the Left image, Right image, and 3D signals. 3D signals can also be in line-by-line or side-by-side modes, which a variety of 3D signal processors support.

Like the BT-LH2550, the monitor features pre-installed calibration software, Cine-gamma Film-Rec compensation, Standard Markers and Blue-only, H/V delay display, monochrome and Cross Hatch overlay display, and split-screen/freeze frame (live input vs. freeze frame).

The BT-3DL2550 3D production monitor will be available this September at a suggested list price $9,900. See the full press release here.

HMX-100

HMX-100

Finally, Panasonic has announced a new mixer, the AG-HMX100. It offers an array of interfaces including four HD/SD-HDI inputs/outputs, two HDMI inputs, and two analog composite inputs. These inputs allow for mixing from a variety of sources, and 3D video is supported as well. This is a unique option, making it the first affordable live switcher for use in 3D production.

Additionally, it includes a DVI-I input for computer use, two DVI-D outputs, a microphone input, dual aux in and audio outputs, a headphone jack, as well as connections for genlock, GPI, RS-232C and tally output. In addition to the ability to mix embedded audio from HD/SD-SDI camcorders and other sources, the HMX100 offers eight XLR and 2 RCA connectors for line level audio inputs, as well as embedded audio output and two channels of analog audio out.

The HMX-100 will be available in June. Read more about the Panasonic HMX-100 here.

What is MTF?

The below article has been taken from Abel Cine blog – http://blog.abelcine.com/

In the last few years, MTF has become a buzzword in both cine and HD lens circles, but there is still a lot of confusion about just what it is, what it can and can’t do, and what it means to the cinematographer in a practical sense. In this article, I will attempt to clear up some this confusion by explaining what MTF means from a technical standpoint.

You may already know that MTF is an abbreviation for Modulation Transfer Function. MTF provides a way to objectively measure image sharpness in a practical and repeatable way that also correlates well with subjective perceived image sharpness.

The smallest practical unit for measuring image detail is a line pair, which is a black line and a white line, side by side. The measurement is line pairs per millimeter, and not lines per millimeter. It is very important to note that we are always talking about a black and a white line pair, and we are counting them as one line pair (1 lp/mm). In the digital realm, we need at least one pixel to represent the black point, and one to represent the white point. So we need a minimum of 2 pixels to image 1 line pair.

Each line pair is equivalent to a cycle and can be measured in either the horizontal or vertical direction. MTF is always measured in cycles per millimeter, which is the same as line pairs per millimeter. We use the term spatial frequency to describe coarse image details. In the old method of measuring resolution, low spatial frequencies would correspond to the larger black and white bars on traditional lens test charts. For example, 5 line pairs per millimeter (lp/mm) and 10 lp/mm are considered low spatial frequencies. High spatial frequencies are usually 40 lp/mm and above, and can go as high as 200 lp/mm, or even more for some highly resolving lenses.

A low resolution lens (low contrast at high spatial frequencies), but with good contrast at low spatial frequencies, can be perceived to be as “sharp” as a lens with much higher resolution (higher contrast at high spatial frequencies) but does not exceed the contrast of the low resolution lens at low spatial frequencies.

Looking at the two lenses on a lens test projector, it would be easy to see that one lens has higher resolution. The higher resolving lens might show the individual black and white lines on the 200 cycles per millimeter target, while the other would show just a gray square in the same place on the target (0% MTF = zero contrast between black and white lines = gray). Yet the lower resolving lens can look quite good through the camera’s viewfinder. This is because, at smaller viewed image sizes, the human eye is more sensitive to the contrast between coarse image details than it is to finer image details.

So how do we quantify the difference between those two lenses in a practical way? If we had the MTF graphs from both lenses, it would be possible to look at the size of the area “under the curve,” and with some experience interpreting the graphs, quickly estimate that the low resolving lens can still be quite good for most applications where the final output does not require the higher resolution (web video, SDTV and, in many cases, HDTV).

But if the intended use was for 2K digital cinema projection on a large screen, or a 2K digital intermediate, the higher resolution lens might give a better result, especially if its coarse image detail contrast is as good as, or close to, the low resolution lens.

MTF measurement is valuable because it provides a method of measuring image resolution that is completely objective. The traditional method of shooting test charts (or projecting test reticles) with resolution test patterns (usually squares consisting of black and white line pairs of a particular spatial frequency) is too subjective. It depends to greatly on the observer’s subjective interpretation of whether or not the target is resolved. Also, MTF is the only practical sharpness measurement method that would allow you to choose the right lens in our hypothetical example above.

Breaking down the term MTF, modulation in this use means contrast. Transfer function in this use essentially means “the ability to reproduce contrast.” In other words, what percentage of the subject contrast that is “fed into” that part of the imaging system (for the sake of simplicity we will consider lenses only) will be “output” by it onto the image plane.

For example, a lens with 50% MTF at 40 cycles per millimeter (c/mm) at f2 (T2.1) will produce an image where a 40 c/mm target will have half the contrast of the target (test chart, reticle or slit). So 50% is the transfer function at 40 c/mm and f2.

In the example photos below (shot with a digital camera from the image projected by a lens test projector), the older lens on the left (Fig. 1) is resolving 100 lp/mm and possibly 140 lp/mm, at least in the X (horizontal) axis. But it is doing so with very low contrast. Some observers would argue that even the 100 lp/mm target is not well resolved.
FIg. 1

The new, high optical performance lens on the left (Fig. 2) clearly resolves 200 lp/mm. But notice that the white bars at 200 lp/mm are slightly gray, not pure white as the lower spatial frequency targets from 10 lp/mm up to about 50 lp/mm. What you are seeing is the natural MTF response fall off of even the best performing lenses. Contrast at 200 lp/mm cannot be as high as contrast at 50 lp/mm. Looking at Fig. 1, our old lens again, notice that even the low spatial frequency targets at 10 and 12 lp/mm are still gray, not white. The lens tested in Fig. 1 has very low MTF, even at low spatial frequencies.
Fig. 2

So how much MTF do you need and at what spatial frequency? In the digital cine world, a good rough guide can be the pixel pitch of the camera’s sensor. No sensor can record details at higher spatial frequencies than the pixel pitch (which must be divided by two since, as mentioned above, you need two pixels per cycle or line pair).

The Phantom HD Gold camera, for example, has 12.5 µm (micron) photosites (pixels), giving a pixel pitch of 80 pixels per millimeter. This corresponds to 40 cycles per millimeter. 50% MTF at 40 c/mm is good optical performance.

MTF can also be used to measure and calibrate back focus (incorrectly but commonly referred to as “collimation”, but a lens cannot be collimated, only light can be collimated). The advantage of using MTF for back focus is that it will give very consistent results with a large group of test operators. Many lens manufacturers prefer it for this purpose.

MTF is a very complex subject, and this blog entry only scratches the surface. I will return to this subject in the future to explore it in more depth.
