Many thanks to the creator of this fine app. It worked perfectly on my rMBP in OS X 10.8.2.

Really great utility that allows you to get under the hood and make a number of low level but highly impactful aspects(including aspect ratios) of a film, including playback speed(not fast forward, but in such a way that the move is made longer or shorter), syncing the audio with the video, (un)cropping, inserting tracks, and a few more. You open the program, then load the movie. You can either watch from the program, export or save it. It doesn't have a million features, but the one's it does have are very useful, especially with video downloaded from the internet where you find a lot of bad initial coding and unusually large media files that bog down after a while.

Ha, what a piece of software, great. I wonder that Quicktime Pro hasn't this feature and others too. With a few clicks I was able to sync a new audio track to a video stream - lip sync! Great!
