Dragged video - can anybody advise to repair using Avisynth?
 

:?: Hi, guys!
I have some problems and need your kind help. I have MPEG-1 video that was converted from 29.97 (NTSC) to 25 FPS (PAL) by simple way. That caused the lost of some frames. The video is dragged on the higher motion scenes, the moving of these scenes is not smooth. How can I repair this problem using Avisynth? Any advise will be highly appreciated!

There is no simple way to go from 29.970 to 25. You have to go to 23.976 (and that is not simple, see http://www.kvcd.net/forum/viewtopic.php?t=8678) and do a "assumeFPS(25)" to go to 25.

Thanks, Dialhot for the reply.

But the main matter is that I didn't convert 29.97 into 25fps. I have received the video at 25 fps which was converted from 29.97 fps previously. I have no original. And now I'm asking to help to make the motion scenes smoother.
Thanks in advance.

How !
What you requested is a script that focus in the "jerking" part of the video but does nothing where the playback is already smooth. I think that is not possible.
