I know I've seen a bunch of topics in here. Is it my understanding that Ots Studio does not support MP4's? I just bought a bunch of them from yourremix.com and now can't use them without converting...which I don't have a program to do...now have to buy yet another program? Is this all correct?
There are free converters...
such as Free Video Converter...
