I was told that when you take an AVI and convert it to VCD/SVCD, the framerate needs to be atleast 25fps for good quality. Most of what I have downloaded are around 12.5 fps. Are these still good to use for good quality? I was also reading of ways you can force the framerate change as well. Wondering how good does that work? Thanks for any help on this me being a strict newbie an all.

Yes, for PAL VCD/SVCD the framerate must be 25fps. If you have downloaded a video at 12.5 fps, you'll need to double every frame during the conversion to MPEG. I think http://www.tmpgenc.net/e_main.html will do this automatically when you use VCD or SVCD template.

Or you can use avisynth scripts. I read something about this somewhere in another forum, how you could double frames to get 25, maybe someone else can go a bit more into details here. Thanks.

Here is an AVISynth script to double each frame:

Interleave(AVISource("MyMovie.avi"), AVISource("MyMovie.avi"))

It's that simple. smile.gif
