    I don't think we support YUY2 on the newer chips today and AFAIK tvtime is pretty limited in the output formats in can use.

YUV - Wikipedia

    https://en.wikipedia.org/wiki/YUV
    YUV is a color encoding system typically used as part of a color image pipeline.It encodes a color image or video taking human perception into account, allowing reduced bandwidth for chrominance components, thereby typically enabling transmission errors or compression artifacts to be more efficiently masked by the human perception than using a "direct" RGB-representation.
