Any good filters for cleaing scratches and spots?

[BluDChyLD]

I'm encoding some nasty footage, which i've managed to denoise with FluxSmooth(10,15). However, there are quite a few black/white spots and scratches on the film - are there any reliable filters to get rid of the problem? I've already discovered "Conditional Temporal Median" are there any better ones?
Thanks

undot will handle the smaller ones, but aside from that you've probably got the best one already :(

conditionaltemporalmedian is so sloooow though. i would really rather encode with the scratches still there if it's an option.

(unless you want to go through every frame with photoshop :))

I can't figure out what source material they used to make the DVDs - there's too much grain for it to be the genuine master copies IMO. There's a lot of scratches on here too which are annoying!

I don't think a filter can do anything about that - scratches come in different shapes and sizes which would be hard for a filter to identify... The encoding speed is bottlenecked@12-13fps because of fluxsmooth anyway, so I don't want to slow it down anymore!

report them for piracy! heheh.

remember those piracy warnings you'd get on rental tapes - if you have lower than usual quality, report them as pirates.

teach them to insult the public by releasing poor quality DVDs

Hehe :) Suprisingly, it's actually an official release through the spanish country "Manga Films". The studio only deemed it fit to be released in Spain, probably because of the poor quality. I've watched a few eps, and the sound isn't the greatest either... It'll do for now, beats VHS anyhow ;)

if it's through manga entertainment, order a r4 copy from australia - ours are good (or i kick my friend's butt for making bad ones...)

I recorded a documentary and it had a section with really old b/w footage which was in a terrible state with splodges and all sort of things.

I had to use this to clean it the old footage section ( a few minutes ):

video=STMedianFilter(video,10,255,112,10)

The docs of STMedianFilter don't recommend this extreme parameter, but nothing else would work. The big splodges were all removed. Ok there is still some small ones left, but the result is an improvement.

Why not try this filter

Try this: http://konstant.freeshell.org

There is another filter which removes pops very good, but i can't remeber the name at the moment. i'll see if i can find it.

greetings,

In my case I had big blotches to remove from most frames, and only StMedianFilter succeeded. Believe me, I tried all the denoisers......

cweb,
may be your old footage was a film?
If so, it must be deinterlaced and converted (by decimation) to 24 or 16 fps, before filtering.

No it wasn't a film. Any in any case with satellite sources I have access to, they are always 25fps.
I recorded from satellite a programme with footage from the studio, plus some b/w news footage which was really old (from the 50's, 60's - one segment was the so called club of rome meeting about the state of the world's environment). These kinds of news footage can be disastrous. I was trying to 'improve' it. I used ApplyRange to apply filters to specific parts of the recording.
