So I came to a conclusion for H.264.

Level 2, 352x208, ~960kbps is the most that the Tube can handle. 768 is recommended. AT that bit rate, the quality is identical to that of an identical sized video at ~1400kbps.

Summary: 352x208, 768kbps(850kbps the Tube says), 380MB

Original video:
Bit rate: Can't get a straightforward answer from my player(VLC) but I'm guessing an average of ~2600+kbps. At some point in the video it has gone over 4000kbps.

Frame size: 640x352
File size: 733 MB

This was rushed so probably someone can get a better combo.

Strange, I got it to play that high. 768 seems to be working great as well.
Maybe it's the frame size to bit rate ratio. I forgot what was the size i used for that bit rate. 768kbps worked well when the video was 352x208, or 320x176.

At the moment it's 352x208, Level 2, 768kbps.

I use SUPER. I tried Handbrake but it seems to be a tad bit slower than SUPER.
However Handbrake seems to be more straightforward and user friendlier.

Page 88 has the setting for Xvid made by Chyan. Try that. 50% compression over the original file and still looks good.

Yeah, that cutting video feature is one advantage that I'd like. Maybe for other encoding I'll use that

Great. If it works, probably it's time for me to switch video converters.
