20 fps -> 30 fps?

[Flux]

I have recored a game video with Fraps but because my computer is slow, I could only record with 20 fps. There is still couple duplicates here and there to maintain 20 fps.

This video will be on Youtube so what would be a good way to add more frames up to 30 fps? I know that Youtube can do it automatically but usually it is terrible and stuttering increases a lot. Just a thought if Avisynth can do the conversion with less noticeable stuttering?

try mvtools by fizick...

it offers a function that can convert framerates: mvflowfps()

1. blending with ConvertFPS()
2. motion estimation with MVFlowFps2() (or something similar)
3. duplicated frames (ChangeFPS() or duplicating every second - will look awful. Maybe that's what YouTube does in default.)
4. go interlaced (I don't know if YouTube supports that).

I'd recommend using MFlowFPS(). It would give the "smoothest" looking results. Interlacing is just a bad idea.
