I currently have the same problem, an AVI at 23.976 fps which I want to encode to PAL or NTSC framerate. Is there the possibility to use mencoder to encode the video, and use some other tool to add these "field-repeat flags" to the MPEG2 stream afterwards ? (just using -ofps 25 or -ofps 29.97 gives me audio desync).
You don't want to use field repeats to convert 24 fps to 25 fps. It will look choppy. Instead just speed it up to 25 fps, and speed up the audio by the same factor. MPlayer has a -speed option to do this (use -speed 25025/24000), but unfortunately no one has written the corresponding code for MEncoder. :(
I want to convert it to SVCD, and my standalone player doesn't have a -speed switch either ;-) I also tried the "telecine" filter, but that gave me terribly choppy video.
you could hack the headers in your source avi file to change the framerate and audio samplerate to make it play faster...
I'll take a look at that. -af resample could then return the sample rate to a sane value... Ciao Martin
