This program is what Apple's QuickTime Player should have been, and then some. It plays QT movies without a hitch, including H.264 movies, and it does so without Apple's irritating nag screen. It also supports full screen playback unlike QT Player.
The real surprise though the full support for the myriad of encoding options, again including H.264.
The only nitpick I have is that each time you go to encode something, you have to re-enter all the settings. QTAmateur forgets all the settings after each encode. If QTAmateur 1.1 gets a preferences setting for encoding options and will remember settings between encodes, it will be just about perfect. The only other feature I'd really like to see (eventually) is a movie info window.
And the price can't be beat of course. :)
