  1. Hello.

    Sony Vegas converts media to RGB32 when loading it.
    I use xvid encoder because it is supported by hardware players, but it's output colorspace is YUV and I don't see any settings to change that.
    So, if my source media is YV12, I have two transformations:

    source(YV12) -> Sony Vegas (RGB) -> xvid output (YV12)

    Is there any freeware encoder with compression and several output colorspaces?

  2. x264 should be OK (RGB is supported) - workaround for YV12 only codecs is to separate RGB as 3 planes (stacked in spatial or temporal way), later they need to be reconstructed for example by Avisynth.

  3. x264 will load RGB but it will convert that RGB into YUV 4:2:0

    Adobe Premiere suppose to keep YUV space all the way, providing you restrain using certain effects ...

    x264 supports RGB, YUV444, YUV422, YUV420. (Although the RGB is stored internally as YUV, it's decoded as RGB . There is no YUV<=>RGB quality loss from the transform, but it's RGB encoding is very inefficient)

    But YV12 is the only format widely supported by hardware players

  5. Most of the lossless encoders can work in RGB. HuffYUV, Lagarith, UT Video Codec, etc. File sizes will be large, of course.

    I agree, HuffYUV and Lagarith both allow you to force RGB decoding and encoding. If I was really concerned about preserving colourspace, that is the route I would go. Logarith will tend to give a better compression ratio.

  7. If compression ratio is important perhaps FFV1 can be helpful http://www.ffmpeg.org/~michael/ffv1.html
