    Hi,

    I need some clarification referring to the color conformance, therefore I would ask for an advice.

    1. If DV25 PAL 4:2:0 material is deinterlaced by avs, and taken by x264 for encoding, assuming that encoded video is then going to be played on a PC,should there be parameters like:
    Code:
    -x264opts colorprim=bt601:transfer=bt470:colormatrix=bt601:fullrange=off
    specified,
    and what is the right way to go? Is this instruction for decoder only or actual color-space conversion ? Is it more convenient to do this from avs script ? what is the right or most preferred way for this scenario ?

    Those x264 switches don't do anything to the actual video data, they are just VUI parameters (essentially metadata) . They are flags or suggestions for the decoder, so you should use them, but the fact is 99% ignore them

    DV PAL is already YUV 4:2:0, so there is no color space conversion, no extra steps necessary in avisynth.
