I'm posting this here because the Divx forums have been worthless to date. I'm using Dr. Divx mainly becuase it is a batch encoder and seems to produce decent results. However.... The video output seems to be jerky. That is, whenever something moves fast on the screen, there is a noticable jerk. This doesn't happen when there is a lot of motion, just fast or complex motion. For example, a group of people walking would not make the picture jerk, but if one of them were to turn quickly, it would. I've tried fiddling with bitrates and picture sizes. A smaller size and lower bitrate produces somewhat better results, but that kind of defeats the purpose of Divx in the first place. Any suggestions? I know this has been encountered before, as I've seen it mentioned in other forums, but to date there has been no real input on why it happens. I'm using a P4 2.4 with 1GB RAM to do the encoding.
