compare mpeg-ts files?

Thanks for answer.. Yes u are right,I couldnt see the colorspace information with mediainfo but .info arg shows it I used pixel_type arg like u say.My first clip was YUY2 and second was YV12..I can do YV12-->YUY2 (clip1=DirectShowSource("C:Examples\x.mp4,Pixel_type="YUY2"")) and compare them but when I try to YUY2 --> YV12 it fails with this error Why does it failed? ANd Is color space conversation will affect to my results? I dont need a specific color space information just correct results are essential.

Arh yes, some clips just show 'YUV' in MediaInfo. "I dont need a specific color space information just correct results are essential." Well if your source (AVI) was YUY2 and was converted to YV12 during encode, should (I think) not be a problem to convert the AVI to YV12 and compare with that, that would take into account the colorspace conversion during encode and show difference due to the encode only. Code:

"Results for YV12->YUY2 and YUY2 -> YV12 are different in my test", Yes, expected as I said above, you are testing two different things, without/with the colorspace conversion. The Video Bitrate is just for the Video Elemental Stream, whereas the Overall Bitrate includes the extra for packaging it into it's container stream. (EDIT: so in answer to your question, the Video bitrate is valid for your test.) Why the clip durations differ?, your guess is as good as mine. Perhaps the container stream durations are in fixed increments in time and differ from the elemental stream duration which will be based upon number of frames and FPS. :)
