  Prores codec

  Posted by Jason Yardley on September 14, 2009 at 3:03 pm

  I’m having a problem with the Prores codec HQ codec in AF when I import a Prores file I drop it into the time line after interpreting correctly, I get green Bars and complete break up of picture, when the picture quality is set to either a quarter, third, half but when I put into full quality the picture is perfect, and I can preview render in full quality, This slows my workflow down considerably, I know that this is a 10 bit codec, the original footage has come from Mpeg 2 and then converted to Pro res HQ, I don’t know weather this is the problem, also If I was working in say uncompressed 8 bit and wanted to do some graphic work in after effects could I convert the uncompressed to Prores and work with it in after effects so that it give me a better color space 10bit as apposed 8bit will the color range be slighty better

  Dave L.,

  This is the first I’ve heard of a “Quicktime Movie in PNG compression” … not that I would ever doubt you, but I was so surprised that I had to look and there it is! Do you know when it was added and do you have any other info about how it compares to other similar codecs? As you suggest to Jason, I use Animation for almost everything, occasionally use the tried and true PJPG and typically avoid bleeding edge technologies until the bugs are fixed, but I like the idea of a newer alternative to PJPG for the times I need particularly small file sizes.

  Thanks.

  Thanks very much, Dave.

  Yes, I think of PNGs for stills and image sequences, but I’ll have to give it a try for video.
