Re: Encoder (codec none) not found for output stream #0:0

You didn't tell ffmpeg what video codec you want, and probably there's no default for MP4. Try:

[c]ffmpeg -r 12 -i my\ input.mp4 -codec copy output.mp4[/c]

(Are you sure you want to do [c]-r 12[/c]? If input is at 25 images/s, this will slow down the movie by a factor ~2, and sound will be unchanged I think.)
