OK, I went back to the video and checked the info window in Quicktime and discovered that I actually encoded it with the 3vix codec, not H.264. Now that I think about it, H.264 didn't exist yet when I encoded the video a long time ago. It's a .mp4 file. QT says 3vix D4 4.5.1, 640x480, millions, AAC stereo, 24fps. 1113.25 kbits/sec. So, given that it's 3vix, should that play smoothly on a PC using a different player, like VLC or WMP? on 10/17/05 6:39 PM, Kunga wrote: > Yeah. Buy a more powerful computer.
