Big fan of this library. It's much easier than writing these scripts by hand. You can also dump a command line version to use elsewhere with the .compile() function. For those concerned about extensibility, you can always use .global_args() to pass arbitrary arguments to FFMPEG if necessary. However this library is well maintained.
