It is said that Shotcut deinterlaces video before filters. It is defined in loader.ini:
# This file defines the normalisers, their fallbacks and the order they're attached
#
# The names on the left are arbitrary, but the order in which they occur is the
# order in which they're applied.
#
# The names of the services on the right dictate the preference used (if unavailable
# the second and third are applied as applicable).
# image filters
deinterlace=deinterlace,avdeinterlace
fieldorder=fieldorder
crop=movit.crop,crop:1
rescaler=movit.resample,swscale,gtkrescale,rescale
resizer=movit.resize,resize
# audio filters
channels=swresample,audiochannels
resampler=resample
The problem is, that I still see interlaced video. Deinterlacing on export is not an option because resize filter is also needed for me.
What to do to get correctly deinterlaced video?
Here is a screenshot of what I see:
Looks like I need advice to use some other app. Some batch processing video app.
I have 115 files I need to correct.
Currently the source videos are interlaced 720x576px 1:1 pixel aspect ratio. They are narrower than supposed.
Finally I need corrected width to height, 960x720px progressive 1:1 par.
I need to upscale because youtube does not support 576p and downscales it to 480p which makes these old videos even more low rez.
I just played with handbrake. Upscale is not possible in GUI. Only command line.
I’ll check how hard it is to use command line.
At least it suppors NVidia encode. I have very powerful GPU.
That’s it. I manually set it from progressive to interlaced under the file properties in ShotCut. Now the ShotCut deinterlaces it.
The problem is solved.
