FFMPEG as Video Transcoder

Added by Carl Wilson · last edited by Carl Wilson · on Sep 20, 2012

Title
FFMPEG as Video Transcoder.

Detailed description
FFMPEG is a free software project that provides cross-platform tools and libraries for converting and playing video formats, including the libavcodec audio/video codec library.

28GB seems excessively large for an 18 minute video, considering entire movies are sold commercially on 9.4GB DVDs. The particular test file used was a 1950s promotional movie for Ford, and the quality was about what would be expected given the age of the film.

The ffmpeg.exe command line tool was used to convert the original to a variety of formats. The chosen formats were:

Motion JPEG 2000 - an emerging archival standard format, based upon the JPEG 2000 still image format
MPEG2 - the standard DVD format
h264 - the high definition format supported by Blu Ray players

It should be noted that the FFMPEG Motion JP2K codec is only experimental at the moment.

The FFMPEG settings used to generate these formats is shown in the tool / code link below.
