very slow video processing

[acro29]

I want to apply fillters on a mp4 video source.
But as soon as a browse through the video in the preview mode it freezes ><

is it my PC which sucks (it is) and can I do something about it (beside buying a new one)

I do know that AVI are no problem. so converting the mp4 into an AVI seems to be an option. if so, what would be the best way to it, I mean which codec to use, and how high the bitrate should be?

Cheers, ACro.

Its not the scripts... I reduced the number of frames, and now it seems to work much better.

Also it is not the script. its the *mp4* files as I wrote up there.
