Compressing good looking Flash videos is an "art"... I'm using ffmpeg for my work and I'm still tweaking things to try and get the best looking video out in the smallest sizes... Currently I'm doing 2 pass conversions. Last night I was viewing some of my 320x240 videos at 800x600 and was surprised to see that there was little if any artifacting.. You can't compare a WMV video to a flash video if you compressed the flash from the wmv. You need to compress it from the source for a true comparison.

H.264 will soon be the way to go as it looks like it's the best compressor out there in terms of quality and bit rate. Haven't got too far in my work on that yet though.. but the file sizes will be comparable (or even smaller) than wmv and yet the quality will most likely be better. I've seen some h.264 flash files that are half the size (150k-200k as opposed to 350k) of what's used on youtube and they are far superior

Why Flash? Because of "web 2.0".. because of youtube... because you can be sure that pretty much anyone coming to your site will be able to watch them as opposed to if you use some other embeded video. When doing your videos, keep in mind that youtube is 320x240 at 350k.. Also, there's no reason to have a high frame rate. I'm doing all mine at 15 fps and also dropping the audio down to mono and a low bit rate. It's porn, not music videos so doesn't need all of that... All of this helps to either reduce the file size or improve the quality for the same file size.

Regarding BW usage, once you've got the traffic, you'd get a proper flash streaming server which will reduce the BW considerably since every surfer isn't going to need to download the entire video to watch it..

As an aside.. it should be clear why all the ISPs don't want net neautrality.. They can all see that the BW usage is skyrocketing and they want to bleed it dry.. Their argument that the high BW users are just a small minority is a false one and they know that everyone is going to be a high BW user in short order because of all the streaming video.
