[HELP] RemoveDirtMC - settings?

[Miranda]

Where can I find the info on RemoveDirtMC settings? It is not displaying in tool tips.

I need a weaker setting that does not result in such a soft output image.

Thanks.

I never came up with good descriptions, so there are none.
Not sure whether it helps, but here is what I can remember:

RemoveDirtMC is meant to be a motion compensated version of RemoveDirt (http://avisynth.nl/index.php/RemoveDirt#...irt_Script)

Not sure whether this helps:
remgrainmode: mode used for RemoveGrain
Modes: 0-24
for explanations, see: http://avisynth.nl/index.php/RgTools/RemoveGrain

repmode: mode used to call Repair
Modes: 0-24
for explanations, see: http://avisynth.nl/index.php/RgTools/Repair
limit: noise for RestoreMotionBlocks
for explanations, see: http://avisynth.nl/index.php/RemoveDirt#...tionBlocks

block_size: block size of MAnalyze, blksize 8 is much better for 720x576 noisy source than blksize=16
block_over: block overlapping of MAnalyze 0! 2 or 4 is not good for my noisy b&w 8mm film source

Ps.: Just noticed the default values were wrong, they should be:

def RemoveDirtMC(input, limit=6, repmode=16, remgrainmode=17, block_size=8, block_over = 4, gpu=False):

see: https://github.com/Selur/VapoursynthScri...oveDirt.py
(uploaded a new dev version which should fix the defaults)

I'm using this on an old VHS, it seems to work better than other filters. I've tried it at the new corrected default settings, but it still seems too strong, and removes quite a lot of detail. I'm not sure what all those options listed above mean, can anyone suggest some less stronger RemoveDirtMC settings, without as much detail loss?

[Selur]

RemoveDirtMC is one of the filters you usually use as a last resort.
To lessen it's blurring&influence you can try to using the 'Merge'-option (https://imgsli.com/Mjg2OTU2) or some masking,...

(Filtering->Vapoursynth->Misc->UI allows to enable additional controls)

Thanks, will try it.
