[HELP] Progressive to Interlaced - HOW?!

[Selur]

Will look at it the week after next, if I don't forget about it.

tryout1 used:

Problem is the decoding call, it requires something liek
For TFF

-vf interlace=lowpass=2:scan=tff -top 1 -flags:v +ilme+ildct

For BFF

-vf interlace=lowpass=2:scan=bff -top 0 -flags:v +ilme+ildct

same issue as with tryout1.

Aside from the bff in the x264 call it looks fine.

=> seems like:
a. Hybrid doesn't properly create the ffmpeg decoding call when not using Avisynth or Vapoursynth for progressive to interlaced output.
b. Hybrid Avisynth/Vapoursynth scripting doesn't care whether you set your configure x264 to output bff or tff.

"Avisynth > Misc > Progressive to Interlace" <- I'll probably remove that there and move it to "(De)Interlace/Telecine".
