Since I won't be getting the upgrade anytime soon, could someone post some screenshots of the new ProRes codec vs. DVCPro HD and Uncompressed. This could be yet another revolution from apple to the video world... or am I being to optimistic?
I've seen the footage Apple showed at NAB to demo ProRes.
It looked the same as the uncompressed footage, after 13 generations. That is to say that they took the uncompressed original, compressed it to ProRes, and then recompressed the result into ProRes 11 more times.
This is vastly superior to DVCPro HD. The closest "common" camera format is HDCAM SR. (If you call a codec which works on $100,000 cameras and $90,000 decks "common.") I can say from bitter experience that HDCAM SR is definitely NOT visually lossless.
REDCODE is supposed to deliver similar benefits, but I think it only works at 4K. Cineform, D5 HD and Avid DNxHD already deliver similar visual performance.
(Actually ProRes outperforms Cineform, D5 HD and DNxHD in PSNR but by a slim margin of 2-4dB depending on which one we compare to.)
The advantage of ProRes compared to Cineform, D5 HD and DNxHD is that ProRes seems to allow you to work at 4K resolution, whereas Cineform tops out at 2K while D5 HD and DNxHD is 1080/25p or 720/59.94p HD.
(I get the notion that ProRes works at 4K from the RED Video on the Apple FCS site.)
Is it a revolution? I don't think so, but it does evolve the state of the art very usefully. Even if it turns out to only work at 1080p, it will be nice ti have a format with better PSNR than DNxHD.
