I'm looking for opinions. Got one? ;-) What is the best supported mpeg4 format. By best supported I mean cross platform player/codec independant . I'm willing to sacrifice some file size and quality for the best overall compatability with the most platforms/players. Any thoughts?

SP MPEG-4 Part 2 I guess. Shouldn't be too many issues with ASP features though perhaps, well other than I guess 3 warp point GMC.

Pardon my ignorance. What codec/front end would you use to encode "SP MPEG-4 Part 2" files (if I'm understanding you correctly)? I've used DivX up to now.

DivX is an MPEG-4 part 2 implimentation. It supports SP and ASP.

It doesn't matter, that is the whole point of a format like MPEG-4. MPEG-4 is MPEG-4. Doesn't matter what app you use.

DivX however uses avi/divx as a container. This is not part of MPEG-4 specs. DivX can of course be placed in mp4 though. With AVI you have additional issues like fourCC's. DivX uses DX50, XviD uses XviD. With mp4, they are both the same. With AVI you also have issues like packed bitstream, which was created as a hack for placing bframes in AVI.

Then again, hardware support for AVI is much more common than mp4 currently. Your question was about MPEG-4 formats though. So AVI is out.

Thank you very much taking time to help, well, a n00b (at least where video compression is concerned). Much appreciated.
