H.264 format at DVinfo.net

Using Media Encoder to output an H.264 BluRay file (I'm assuming that's the setting I have to use for an HD quality H.264 since the regular H.264 wouldn't let me choose a height and width over standard SD sizes. The output gives me three files: one is .m4v, one is .wav, and the third is .m4v.xmpses.

If I'm setting up the H.264 video to stream in a flash presentation, which of those files do I need to embed into the program? Just the .m4v file or do I also need the .wav and .m4v.xmpses files?

How do I best use the H.264 format? Would a .flv file be just as good? I've read that H.264 allows for a much higher quality while maintaining a smaller file size and a faster render than a .flv will allow. Is that correct?

Sounds like it's exporting your video and audio as separate streams, i.e. it is assuming that you have BD authoring software that is going to mux them back together again.

(Ignore the xmpses file).

There should be an option to export as a muxed program stream - which would likely have an mp4 extension (thats what Procoder and Handbrake produce, anyway).

As of late 2007, flash video now includes support for H.264. I believe such files are supposed to use f4v as their extention, but they can be called flv and still play.
