what order is the crop & resize and deinterlace filter on hybrid? - jono2 - 08.10.2022

i want to know what position is the crop & resize and deinterlace on hybrid. (filter order)

who is the first one?

can i change the order of the filter?

for example
deinterlace()
resize()

or 
resize()
deinterlace()

?

You can see&change the filter order wen using:
  • Avisynth: under Filtering->Avisynth->Misc->Filter Order
  • Vapourynth: under Filtering->Vapoursynth->Misc->Filter Order/Queue
for FFMpeg&Mencoder it's hardcoded and the same as the default deinterlace, then resize. (deinterlace > crop > resize)

Side note: Hybrid always uses "crop < rotate < resize < letterbox" this can't be changed.

thank you very much.

another question.

i want to encode an interlaced mpeg2 vob video 29.970 fps to progresive 23.976 fps. every 5 frame, there is 2 ghost frame and 3 normal frame.

With tivtc there is weird noise in 1 frame at some frame.
for example on frame 929, look at the joystick.

there is no such weird noise on frame 928

Have you checked whether the content is telecined, interlaced or some mix?
If you Bob the content and your got motion in each frame it's interlaced, if you got repeated frames in a pattern it's telecined.
(see: https://forum.selur.net/thread-1961.html and https://forum.selur.net/thread-1961.html)

I assume that your source content is telecined, tweaking the TIVTC settings might help.
Images do not really help with interlaced/telecine diagnostics, share a short sample (10sec is enough) which has horizontal movement in it, if you need direct help.
Just from your screenshots, I can't tell what causes the artifacts.
If you look at the content while using a deinterlacer in bob more, and these artifacts are there, then it's an issue in the source and TDecimate might just use the frame with more artifacts since it assumes those are details.
