Compression to divx5 - DEPRECATED
last update 20070225
- use of codec 'divx' to encode an mpeg4 compliant film is not recommended by the transcode man pages anymore, you should use instead 'ffmpeg'
- this page is deprecated but kept just in case some former rgb colour-encoded stuff was still hanging around....
- to find out more about the use of a piece of software and its options check man pages or respective web-sites:
www.transcoding.org - transcode
Transcode from rgb_dvc.mov to divx5
- avoid RGB colour model and use YUV for better compression and increased compatibility with other multimedia players!
- 26min documentary:
note that this film using RGB (instead of YUV - my mistake...) was first rendered by Cinelerra to mpeg2, then reloaded into Cinelerra's assets for a second compression producing rgb_dvc.mov, and only then compressed via transcode
1st mpg release: 544M lindy_by_frogs_2200Kbps_720x480mpg2 2nd compression: 2.4G lindy_by_frogs_2200Kbps_720x480mpg2_to_dvc_12fps.mov 3rd compression: 54M lindy_by_frogs_2200Kbps_720x480mpg2_to_dvc_12fps_to_divx5.avi
the command line is split for better legibility (back-slash ' \ ' means continue to next line):
transcode -i lindy_by_frogs_2200Kbps_720x480mpg2_to_dvc_12fps.mov \input file
-o lindy_by_frogs_2200Kbps_720x480mpg2_to_dvc_12fps_to_divx5.avi \output file
