QTCoffee allows you to manipulate QuickTime movies (and other QuickTime readable media such as iTunes audio files) via the command line.
The QTCoffee tools allow you to modify movies by extracting tracks and chapters, scaling & rotating tracks (or the entire movie). You can also multiplex movies together (e.g. take a video track from one movie and a sound track from another), join movies together, and split a movie into equal duration parts, at specified times, or by chapters. Files with only MPEG-4 video and/or AAC audio can also be saved as MP4 movies without reconversion.
Why would you want such a thing? Well, if you only happen to need these particular features, and don't want to pay $30 for Quicktime Pro, then this is for you! More importantly, these utilities can be used inside shell scripts and are therefore very useful for batch processing. We think of them more as complements to Quicktime Pro rather than replacements for it.
QTCoffee is donation-ware for personal and academic use. If the tools are useful to you you are encouraged to purchase a license or pay whatever amount of money you feel is appropriate. If you use it for commercial purposes (even if you don't make any money specifically off the project) you will need to purchase a license at $10 per seat.
Here are some key features of "QTCoffee":
Joining (concatenating) movies or audio files, so they play one after the other, with special support for pass-through joining of MPEG-4 video and AAC audio to MPEG-4 files. (See also our shareware iTunesJoin scripts.)
Multiplexing of movies so they play at the same time. Useful for:
Putting together audio and video tracks from other utilities
Masking unwanted (noisy) parts of a video
Letterboxing content
Picture-in-picture effect
Scaling movie tracks (for resizing video content)
Changing the playback rate of movies or audio
Extracting or removing tracks
Extracting or removing chapters
Splitting a movie into equal duration pieces or at specified times
Splitting a movie into individual chapters.
What's New:
Corrected a bug in the -timescale -sameAsTrack option that was introduced in 1.2.3.
