framerate.py

August 27, 2007

A little utility to convert the framerate of a video clip of arbitrary
format, using the yuvmotionfps and ffmpeg utilities.

The advantages of this script are:
 - it's pretty simple
 - its input and/or output can be piped
 - it eliminates the need for typing manual commands, and creating huge
   yuv files on your disk.

Prerequisites:
  - ffmpeg - should be on your linux distro's feeds
  - python version 2.4 or later - ditto
  - yuvmotionfps - get from http://jcornet.free.fr/linux/yuvmotionfps.html

Installation:
  - rename to a convenient name (I've just called it 'framerate')
  - stick in your PATH
  - change permissions to 744

Usage:
  - run with '-h' for help
  - note that audio gets ditched, and resulting video must be
    re-muxed with audio afterwards

Example:
  - framerate -f mov -vcodec mpeg4 -r 25 -b 2000 infile.avi outfile.mov
