Is there anything I can do to fix this? Its from a 1983 PAL Umatic master.
sample clip
LOL, I think I found something, try:
Code:
# removing flickering using ReduceFlicker
clip = core.rdfl.ReduceFlicker(clip=clip, strength=3, aggressive=1)
# removing grain using SMDegrain
clip = smdegrain.SMDegrain(input=clip, interlaced=False, dct=1)
the dct=1 in SMDegrain is what really helps. (but, yes it's slow)
attached an encode with:
Code:
# removing flickering using ReduceFlicker
clip = core.rdfl.ReduceFlicker(clip=clip, strength=3, aggressive=1)
# removing grain using SMDegrain
clip = havsfunc.SMDegrain(input=clip, tr=4, interlaced=False, dct=1)
# removing grain using SMDegrain
clip = havsfunc.SMDegrain(input=clip, tr=4, interlaced=False, dct=1)
=> so with some tinkering this might really be somewhat fixable.

Thanks, will this also work on an interlaced upscale?
Probably, but a lot slower,... dct=1 will slow stuff down a lot when the resolution increases,...
This is something that should be fixed during capturing the further you go down the line the harder it will be to fix,...
on a hardware side of things, tbc is made to fix stuff like that....if you have one at hand....
How do I add SMDegrain twice?
You use 'Filter Queue' instead of 'Filter Order' (read:
[INFO] About Vapoursynth Filter Order/Queue), then go to SMDeGrain and add it.
With 'Filter Queue' enabled there are '+'and '-' controls to the right of each filter.
(will probably move these to the front in the next release)

Looks interesting, any plans to add it to Hybrid I wonder?
