FFV1 422p not YUY2?

[SturmMD]

I'm having trouble encoding in YUY2 with FFV1. I set it to 422p and forced the input colorspace to YUY2. But when I load the clips in an avisynth script, their info() is indicating they're yv12. What am I doing wrong here? Thanks in advance

AviSynth is requesting YV12 first (by default). If FFV1 is not able to deliver YV12 then AviSynth asks for YUY2. Try

AviSource("file.avi", pixel_type="YUY2")
