25fps to 15 fps

[audyovydeo]

Hello

I'm at my first attempt to make a video for 3gp, and find that it requires 15fps. Since I've always worked in 25fps upto now, I just don't know how to downgrade a video frame rate.
Avisynth documentation didn't say much in this respect. Anyone here got any hints ?

thanks

You didn't look very far! ;)

If the source really is 25p (rather than 50i) a simple conversion might look a but choppy. If so, you need a more complex solution, e.g.

and other suggestions in that thread.

Cheers,

Indeed !!

ChangeFPS does the trick. ConvertFPS stumbles ("New frame rate too small"). And I prefer dropping frames to using the Switch mode.
