Framerate Conversion 12FPS --> PAL

[mvdbosch]

I've got an very odd XVID file which is 12FPS but which I would like to convert to standard PAL (or NTSC, i don't mind). Which tools should I use and how shoud I use them????

You can use AVISynth.
The ChangeFPS command would duplicate frames to meet the new framerate. I would change it to 24, and then use the AssumeFPS to speed it up one frame per second. That way it would essentially double each frame for a smoother increase. The last frame per second would be handled by the AssumeFPS command.

www.avisynth.org

The script would look like this:

AVISource("c:\folder\movie.avi")
ChangeFPS(24)
AssumeFPS(25)

I've never tried it, so I'm not sure the motion would look smooth, but simular methods are used to produce progressive video for HDTV, so in theory it should work. Let us know how it goes.

You can also use VDub, doin off the top of my head.

Open avi in vdub.
Direct stream copy both video & audio.
The look for a setting to framerate to 25.000 fps.

Sorry its vague, have not got vdub on this system.

Not a good option. That would double the speed of the clip, where mine only modifies it by 1 frame per second (4%)
