Opensource Video Editing stuffs

Hey guys and gals.

Two questions…
Does anyone know of any good opensource video editing stuff? I tried jakasha or something like that and it was worthless. Also couldn’t open .MOVs, though that might be because that’s a proprietary format? I dunno.

And if no one knows the answer to that

does anyone know of any decent free video compression software, specifically for .MOVs?

Thanks y’alls.
