freeware that let's you change the speed of a video?

[DaneClark]

I am trying to get clips to sync up to the audio I have in .avs editor and there's got to be a better way, the fact that Premiere uses different units of measurement for it's speed/duration feature than avs really really doesnt help and for some reason clips seem to be coming out at different speeds even when I remap them using the exact same percentage in pro when they shouldn't be since they all have the exact same framerate and stuff and just now I finally did get the video clip to be the exact same length as the audio clip it still didn't sync up when I know it should have because what I'm trying to do is colorize stuff and I can see the original b&w clip under my colorized version in avs before I go into "edit overlay" to make it cover the whole screen, there's got to be a better way to get clips to the exact duration I need them to be, someone PLEASE help
