Did you speed up some of the video or did you rip it at a different frame rate?
or does it just look that way because these are prelim videos?
It's just that some of the shots, especially the digitally dependant ones look very fake in their current state...and they don't in the film... and it's eaither because you ripped at a different frame rate or sped up the video...
As far as the editing... I like what you're trying to do with the movement of Anakin standing on the ledge of Mustafar to after Yoda and Palpatine start fighting... I do feel that the sound is a bit jarring.
If I may make a suggestion. I would try editing the video how you want it... then figure out the audio latter... IF you dont' have it already, I'd recommend downloading my complete Episode III score edit. You can use those and the center channel to rebuild the audio track... then maybe a few sfx here and there from the original edit....
But that's just my suggestion...
