  1. Hi all!

    Just tried playing with ffmpeg in making prores today.

    Was really happy with the new feature, worked for both Windows and Linux (Ubuntu 11.10)

    However, when I brought them back to my mac Final Cut Pro, I notice a slight color shift when compared to the original clip, seems like saturation was bumped up a bit. It is also apparent in the RGB Mixer scopes too.

    I tried using "-pxl_fmt yuv422p" and "-dct8x8" but none of them fixed the issue.

    Here is the command I entered: ffmpeg -i prores_test.mov -vcodec prores prores_test_output.mov

    And here is the info for both clips through ffmpeg:
