you can switch out as many clips as you like, just as long as they have the same name....
if you want to save your editing you should make sure your clips are the exact same when changing over to a new clip... aparently vegas just kinda points to a file... or something... i switched out a clip with a completely different clip just by renaming it... and it kept the same editing, but it had a whole new scene there instead......
im not sure exactly how it works, but as long as the file is exact in lengh and beginning and end, and you rename it to the original file, then vegas should still work with it.
