I have an M4V video and I've used several different converting programs to convert to media files that vegas can import. But vegas always says "None of the files dropped in vegas could be opened" Why would it still say that if they are .avi / .wmv / .mp4 files? I've used aimersoft video converter, the VLC built in converter, Format factory, and many others. None work.
Edit: I got it to work with the MP4 (AVC) setting. Should I delete this thread? if thats possible? Or could this be helpful to someone
