Compression varies depending on codec
Authored by: jvr on Jul 28, '06 09:00:56AM

I send & receive QuickTime movies rendered in a variety of codecs, and the level of compression accomplished by zip does vary, depending on the codec used. Yes, there are some codecs for which zip is not helpful, but there are others for which it cuts the file size nearly in half.

Example:
A 15 second logo animation with alpha channel, 720 x 486, 29.97 fps, 32-bit Animation codec.
Before zip: 199 MB
After zip: 122 MB

That's enough compression to save a significant amount of time on upload over my cable connection.
