How would I do Slow Motion with AVISynth?

[Huge]

Hello,

I have a clip I'd like to slow down and keep the best quality I can. How would I do this in AVISynth?

If your source is interlaced, you could try the smoothdeinterlace filter. I can create very smooth 50fps clips from 50fps interlaced sources.

Otherwise there is not much for you to try in AviSynth, since other processing methods requires motion prediction, for non-blended frames. This is done for example with the RealViz Retimer package (expensive commercial package).

i guess the 2nd best after sh0dan's method would be to reduce the framerate, or duplicate each frame...

Did you try assumefps()? and then convertfps() to bring it back to your framerate.
