Do you have / use an alpha channel in all of this ? I'm feeding it 'dry' non-alpha rgb48 which vapoursynth wraps in b64a for VfW. Maybe I should try with a dummy alpha channel.

Another (very minor) thing. Opening a .vpy file now requires me to explicitly select the avisource reader. Just opening the .vpy gives an ffmpeg error, so I guess the ffmpeg input driver tries to open vapoursynth scripts now. This wasn't always the case.

edit might it even that there is an avx(2) codepath or something enabled in the cineform RGB mode that my old i7 doesn't support?

Everything else was exactly the same as your test setup , RGB48 . I tested 1280x720 (maybe you have some weird dimensions causing crash?)

I just dragged the vpy to vdfm , and it automatically chose AVI, with "internal DIB decoder (b64a)" as reported in file=>file information

The CPU I tested on has avx2 . Win8

Was that on XP ? Some ffmpeg changes made XP support more difficult, maybe it has something to do with that ?
