It's a pity about Super 16, it seems to be the 500 ASA stocks that have the problems during the transmission chain compression. Personally, I only use only that speed if I really need it, fortunately for most work 200T or even 100T is fine and the 50 ASA daylight stocks are great.

However, HDV is in the same position as Super 16 with Discovery HD and the BBC HD.

On board sound recorders were made for the Aaton for those people wishing to shoot sound while working alone. The main problem with single person crews is that the sound is a bit of a compromise compared to having the sound recordist with the mic boom etc..

I really couldn't tell the difference between most of the 4K, 2K and HD at the distance I was from the screen. The biggest difference was in the production values and quality of the camerawork
And it stands to reason. As you go to higher resolutions you need to have much larger screens or you need to sit closer. So in reality the push for 4k and now 6k and beyond is becoming as silly as the Megapixel ratings in digital cameras. 10 bit and above colour resolution is more desirable to me than outright resolution. As are higher progressive framerates.

To contribute, I've also noticed quite a lot of folks taken by the number of pixels as well. I don't think it helps to have the sales people at electronics stores to go on and on about how "you NEED to have FULL HD!". That's in reference to 1080p vs. 720p. Like John says in the interview, people for some reason need to have some sort of number to grab on to.

Sure, I like HD a lot more than I like SD, but I think I'd rather see High-Definition evolve to faster frame rates and better color like Simon said above.

Mark Donnell February 16th, 2009 11:15 PM

I agree that faster frame rates and better color are more important than higher resolution, but I would add greater light sensitivity also. Especially the smaller HD cameras are just barely adequate for indoor recording without lots of extra lighting.

I have to agree with you 100 percent on that one, Bill. The CG shots in modern film making stand out like a sore thumb to me. I tend to shy away from action movies for that reason alone.

I had to switch over from "Pearl Harbour", having just changed over to it in the middle of the attack. The thing just looked like a video game and now "Tora Tora Tora" just looks more impressive with time... Although some of the ships moored in the harbour do tend to look a bit "modelish" at times in some shots, but the "Pearl Harbour" ships often look like GCI anyway.

BTW The previous time I started watching "Pearl Harbour" I didn't even get to the attack before turning it over and that wasn't to do with the CGI.

Benjamin Button was shot, edited, timed in 2K.
Just talked to VFX head on the show.
No DI was used.

2K timing is for all intents and purposes a DI...? The term is a bit confusing in a pure digital workflow as it was coined to refer to projects that originated on film, but it is widely used now for all-digital projects, generally indicating a digital color correction process.

Christopher Drews February 21st, 2009 03:46 AM

Yeah. It is confusing. It's also confusing when you talk about Red 4k, but cut in a DI, then go back to Red 4K for timing. I agree that a new term should be used when talking 1's and 0's all the way through. I vote for DF = Digital Film.

Brian Drysdale February 21st, 2009 06:55 AM

Each stage in a workflow will need to have a title or a term, so something as loose as Digital Film won't cover this. A DI is part of a process, just the RED's Bayer 4k data is another part. This is no different to say creating a film print from a film negative, there are different workflows and a number of stages in each: these can include creating a DI or interpositives and internegatives.

What is important is a common terminology that doesn't include things like a "telecine" for colour correction, which seem to develop because the colour correction system was attached to the telecine machine, rather than transferring film to video.

If these terms get picked up by the industry as a whole is another matter. The BBC for example, had (perhaps less now) different terms to the rest of the television industry. For example, CSO (Colour Separation Overlay) for Chromakey.

I remember reading awhile back about the reasoning behind why Panavision decided to use a 1920x1080 35mm sensor in their Genesis system versus a higher resolution sensor. Apparently, they chose this resolution because it was the best compromise between picture quality and light sensitivity. I suppose this is why Sony chose this frame size for their new F35, considering Sony makes the chip for both companies.

Brian Drysdale February 23rd, 2009 02:35 PM

It's a 12.4 megapixel sensor converted to an 1920 x 1080 array, which since it's full RGB has advantages over a Bayer sensor.

resolution
 
Unfortunately for me I've never been to a good projection showing for matching various resolutions against the other. That being said I can easily tell the difference on a 24" dell monitor between 720p and 1080p or 1.5k vs 2k in Apple Color. like within a few frames of watching it I just know. I can also usually see every pixel on the screen in a theatre if I'm not too far from the screen. I can honestly see all the little squares and although resolution doesn't make good stories it does mean something to those of us with 20-20 or better vision. In the case of the RED the 2k is OK at 1080P. 4K is massively better at 1080P and 3K is basically the same at 1080P. Most people don't notice, can't tell, or don't care but saying that there isn't much difference between rezzes on a big screen doesn't hold true for me. But my left eye is getting a little softer than my right so in 10 years maybe a cell phone camera will be fine for me.

Red One Camera Test and demos

Brian Drysdale April 12th, 2009 06:22 AM

The RED has a Bayer sensor as against the 3 x 2/3" chip and by it's nature the 2k Bayer would be expected to be less resolution than the traditional 1080p 3 chip cameras. That's why the 2/3" Scarlet will have a 3k chip.

I believe the debate is more about the aesthetics of 35mm DOF as a requirement in a cinematic film compared to the deeper DOF found on a 2/3" sensor rather than resolution.

Ethan Cooper April 13th, 2009 06:35 AM

Here's the bottom line on all this talk about 2K, DI, 4K, Bayer patterns, whatever. I saw Knowing last week (shot on Red) and although not a great movie, it looked and felt like a film to me. End of story.

I'm highly curious to see what Crank, High Voltage looks like on the big screen. A prosumer HDV big (relatively) budget Hollywood film. You kidding me? It'll be interesting to see how that holds up in the theater.
