I'd like to do this too but in my case I think I would have to
superimpose the png on the mpeg stream before converting to h.264/mp4.

Going from SUP/SON to SRT for use in MP4 is pretty pointless because you
have to use OCR and it isn't very good.

Has anyone superimposed SUP/SON on to a video in any format using
mencoder or similar?
