Studio Daily Blog » The great codec bake-off

Frank Capria has written a nice little post over at the Studio Daily blog that is a quickie comparison between Avid’s DNxHD and Apple’s ProRes 422. This is an important comparison as these formats are direct competitors to each other. It’ll be interesting to see if more of these are done by other editors and compression experts in the future to see how they fair with others as well.

    Hmm, interesting and depressing.

    I am wondering if you need to alter the After Effects Setup file to get the 10 Bit to export in After Effects CS3 like you do in After Effects 7.0? If so that might explain why the 10 bit doesn’t look any better than the 8 bit.

    To be fair, ProRes is a YUV codec primarily designed for FCP and a test in AE could add other factors that may not be a problem in FCP. It would be interesting to see a test in FCP comparing an uncompressed capture with a ProRes capture of the same footage.

    I might be wrong but it looks like ProRes performance is killed by yet another Quicktime induced gamma shift. I would expect a non-performing codec to show lots of macroblocking – especialy in the noise in the lower part of the source image – but the fact that the image is totally albeit faintly visible in the difference layer makes me think there is a gamma problem. This doesn’t explain why DNxHD doesn’t have a problem.
