Isn't it the case that YouTube reencode everything they receive to
250kbps 320x240 using the flash6 adopted Sorensen mpeg4 asp codec?

In which case doesn't it make sense to give them the best quality they
will allow to be uploaded, to avoid garbage being mangled into worse
garbage? Aiui, the only upload restrictions are 100MB size limit.

Hmm, I wonder if you're getting 448x336 from the fact the vids playback
at about that resolution. If so you should be aware they only transcode
them to 320x240, then upscale them on playback.

The only real way to get halfway acceptable results from YouTube is to
ensure you only upload very compressible content, so that when they
mangle it it's still viewable. If you look at the vids they offer up as
to examples of quality, I think you'll find this to be the case.

Another tip is to make best use of their 4:3 aspect. If you have 16:9
content, either zoom it or if you have the time, pan & scan it.
