HD Flash videos
Thanks to my bandwidth-safe media server account, I re-encoded and reposted a couple of high-definition videos. I played around with the bitrates in CS3's encoder, and settled on around 9Mbps. That's pretty high, which will result in clips buffering for a while even on broadband connections. But it's HD, so that's to be expected. CS3 will go up to 10Mbps, but I didn't see much of a difference between 9 and 10. 6 megs actually didn't look all that bad, but I figured since I'm not bandwidth-pinching I could spring for an extra 3.
I'm not 100% impressed with the Flash-based encoding (it still looks a little soft even at the full 10Mbps), but I like it better than Windows Media. Windows Media encoder will go up to 20Mbps at 1080i res - which looks great, but is too big for practical web use. I'm using a 944x528 frame size that will fit inside this site's 1024-optimized layout. Any larger than that and the Flash encoder starts getting noticably softer.
