I'm wondering, is there any software out there that can convert and edit ANY of the most popular video formats/containers? (mpg1, mpg2, mpg4, avi, vob, etc.), and which use professional-quality transcoders?

I'm sure folks who do stuff for Hollywood have to do this kind of thing all the time, and use professional grade tools.

What are these tools? Assuming cost would be no object, what is there out there that is an "all in one" (or nearly so) solution? IS there such a thing?
