Oh oh!
What have I missed Al, and do you have a suggestion for how I might fix it?
Should I output 601 from the VapourSynth deinterlacing? If so, I'm not sure what I'd need to change.
Should I somehow flag that it's 709 during ffmpeg encode? If so, again.. I'm not sure what I'd need to change.
Thanks for spotting that Al!
FYI - I checked my input video with the following:
Code:
#!/usr/bin/env python
# import the needed modules
import vapoursynth as vs
import havsfunc as haf
import edi_rpow2 as edi
core = vs.get_core()
# read the clip
clip = core.ffms2.Source(source=INVID)
clip = core.text.FrameProps(clip)
clip.set_output()
Chroma Location: 2
Matrix: 2
Primaries: 2
Transfer: 2
Hopefully that's helpful info... but I recall you saying seeing a "2" there means unknown. All I know from MediaInfo is that the original AVIs are yuv411.
