Hallo everybody, this is a test of your emergency broadcast system...

How about reverse filtering(temporal cleaning, denoise)?
Problem 1: sometimes there are holes/artefacts in next frame, reverse you can kill them like they were bild
Problem 2: on changed parts the temporal filter has to learn again, those parts appear most on keyframes, you know;-)

One idea is bitemporal filtering between keyframes, but how to get it automaticaly. I tryed by renaming framesequences twotimes(do anybody know what I mean???it's real work for a batchfile and the HDD!!!).

Please PLATE me!

That's probably the weirdest message I've seen yet on this board.

Anyway, using AVISynth, you can reverse the input so it plays back-to-front and also filter it that way. Reversing again will put it back in the correct order...

thx 4 answer!
...sounds great! How do I?(I'm standing on the hose)

Just to say it again:
I did REVERSEFILTERING on single pictures(sequence generated by vDUB or TMPGenc), by renaming(the work of a batchfile) the picturenumber in the filename. For a 4 minutes(or less then 10) video it's the best way, I think so. A sideeffect is the need of much diskspace. But, to get good KEYFRAME's, it's worth it!

First, keep standing on the hose, it's probably a good idea!

- just kidding.

Second, look up AviSynth and look through all the filters available. Read about the http://www.avisynth.org/index.php?page=Reverse filter.
