Actually there are differences between vfw decode of 9.2.1 encoded vs. vfw decode of vdfm native encoded . 1st frame is identical , as are a few others. But other frames are not.

But you said : "I am not sure it is possible to compare results bit-to-bit from current sdk vs vfw 9.2.1 implementation. Probably something was changed. "

Code:

a0 = core.avisource.AVISource(r'F:\_Video Tests\QT Prores\cineform_filmscan2_native.avi', pixel_type="v210")
ap = core.avisource.AVISource(r'F:\_Video Tests\QT Prores\cineform_filmscan2_v9.2.1_prog.avi', pixel_type="v210")

d = core.std.MakeDiff(a0,ap)
da = core.std.Levels(d, min_in=511, max_in=513, gamma=1, min_out=0, max_out=1023, planes=[0,1,2])

da.set_output()
