I tried finding information in this forum about this conversion and all I found was to use avisynth but not instructions on how to do it, could you please provide them here using this or another program capable of doing this conversion which I tried to solve and keep getting unsynched video.
Maybe a bit more info needed like what form are you trying to convert (AVI, mpeg, vob, etc) and to what format ( vcd,svcd,dvd,avi, etc).
Encode your current PAL video to NTSC 720x480, but keep the framerate at 25fps.
Demux the video from audio.
Load the video into dgpulldown.
Convert 25fps -> 29.97fps.
Use the dgpulldown.m2v with the original audio to author.
