Subject:Re: Question: video on web pages From:Faun deHenry <faun -at- SANCITY -dot- COM> Date:Sat, 28 Feb 1998 14:34:26 -0800
Deborah:
Which compression algorithm is your client using? Cinepak? AVI? MPEG-1?
MPEG-2? FLC? Or does your client intend to use a streaming video
technology?
The answer to your question depends in part upon these issues.
Other issues are:
How many frames per second are in these videos? 10? 15? 25?
29/30?
What is the size of the frame? Is it a 4:3 ratio? Custom?
What image compression is being used? 8-bit? 16-bit? 24-bit?
How much temporal compression is your client using in these
videos?
What is the lossy factor that your client is using for these
videos?
Raw video for one second at 640x480 pixels, 24-bit color, and 30
frames/second uses 27.6MB. A minute with the same parameters uses
1.66GB.
Hope this helps.
