I use VLC media player for screencapping, but I think for larger videos it doesn't cap as well or as frequently, so they become choppy and not very fluid.

I tried following the automatic capping here http://www.pibby.com/blog/2007/01/auto-screencapping-in-vlc/ (It translates to PC) which was really good because it's less work, but the screen caps were also not very continuous. I changed the recording ratio to 1:1, but that didn't really help.

Is there any other program I could use, or anything I can do with VLC to help me with better screencaps for animated icons?
