I don't know if others have experienced this, but when I converted the recorded Sims 3 videos using VLC, and played back the converted videos, it looked like my sims were twitching all the time or like there was a glitch.
I've had better success using Handbrake to convert. Good things about this software too is that it's free and it also rips DVDs. Hope this helps others.
Thanks for the heads-up about VLC. I actually just needed something to preview my videos so I just know what they're even about, so I can upload them to my studio, and that was just the info I needed. Thank you very much for posting the OP
