How do you do film speed effects

[KarmaCrow]

Does any body know how to make your movie go faster (like those effects where the night passes in 30 secs or where you see the clouds move fast in the sky)? Any help is higly apreciated!

This is a little difficult, but here goes.

You will need Avisynth the decomb plugin for avisynth, and virtuadub or nandub. The easiest way to get all these installed properly is to get GordianKnot from www.doom9.net

You need to construct an avi synth script like this

LoadPlugin("C:\PROGRA~1\GORDIA~1\decomb.dll")
AVISource("y:\Mymovies\test.avi")
decimate(cycle=5)
decimate(cycle=2)
decimate(cycle=2)
decimate(cycle=2)

The decimate(cycle=5) statement means that 1 in every 5 frames are removed, (cycle=2) means that evey other frame will be removed.
In total the four decimate statements above should mean that 9 in every 10 frames are removed (Assuming that I got the math right).

Now when you load this into virtualdub, virtualdub will assume that the framerate is 1/10 of the original, to change this you need to select video->framerate and change the framerate back to the original, and then encode the movie as you normally would. The result should be a movie that plays back at 10 speed.

If you also want the audio, besweet should be able to speed up the audio for you.

Thanks a lot, I will try it

This solution works perfectly. Definitely good if trying to achieve this kind of effect.
