So take the original source file (like, if you have an uncompressed source, use IT), generate an XviD and a Flash file, and ensure that they look pretty much the same. (This is made easier if you examine selected frames under high zoom.) Then tell us the parameters you used for both processes. Provide screenshots so we can see exactly what's going on.

You're making an outrageous claim here, and as such, we demand hard evidence for the claim. If you can't provide it, you might as well have not said anything.

Chances are that the XviD will be smaller AND will play back at a more guaranteed frame rate across ALL platforms that XviD runs on (which includes Mac OS X, Linux/FreeBSD/many other free UNIX-like operating systems, Windows...)

In fact, I'd wager that that would be the case, because I've done several experiments with raster compression in Flash myself. (The short conclusion: The results sucked, in comparison to what I'd get from a system DESIGNED for raster compression -- you know, like XviD, DivX, MPEG-1/2, etc.)

Bah... whatever... But it is still better for DLin' huge files. YOU could also stream it and the like.

You can stream RM too...at a hell of a lot better quality/compression. I agree with Zarxrax...you really DONT get it do you?
There's a fine line between genius insanity...and I've crossed it 67 times.

So? I can stream MPEG, too, at far higher quality. Or RealMedia, Windows Media, or one of the streamable Quicktime codecs.

When streaming, the file size is irrelavent. Rather, it depends on how many bits you can throw at your client per unit time. Considering that I can get higher quality raster compression per bit with a system designed to do compression of such data, I think I'll be smart and use that system.

If you can prove that Flash -- a vector-based animation system -- will compress raster data better than, say, DivX 5.0.3 or the latest XviD, that'd be cool. But you've not done that.

flash MX has added a version of the advanced sorenson codec that apple loves so much


so yes... plash = vector graphics...

Flash MX has added the ability to embed video into it.... there was a whole lawsuit planned since apple has a deal with sorenson that only they get it's advanced codec....

sorenson said that apple and flash don't compeate...

blah blah blah

so its basically a sorenson encoded quicktime file

So why not just use Quicktime with the Sorenson Video codec and spare your audience the Flash baggage? :P

I mean, I can play Quicktime/Sorenson videos on any machine I have, at a more-or-less guaranteed framerate, while Flash is, at best, iffy...
