Done. Hacked the AVI to 25fps. Sox will hopefully take care of the audio.
I made the audio (25/23.976) times faster (this went correct, as (audiolength_before/audiolength_after) == (25/23.976)) and muxed the audio file back into the hacked avi with "-oac copy -ovc copy -audiofile audio-25.wav". But all I get is terrible audio desync. That much for a PAL SVCD.
Doing stuff like this is always dangerous to A/V sync. What I was suggesting was to change the audio samplerate in the avi header, not demux and remux...
One other thing I tried it to use -fps 29.97 -ofps 29.97 -vf telecine to make an NTSC SVCD (my standalone player can handle NTSC, too). But this gives horrible quality after recoding with vcodec=mpeg2video. Any other hints ? How do you out there convert a FILM video source to DVD or SVCD?
You'll have to use ildct and ilmv (lavc options) to get remotely tolerable quality like this, and even then it will be bad. Not only does hard telecine make it difficult to get good progressive rips; it also trashes the video quality. :( Rich
