Which compression algorithm is your client using? Cinepak? AVI? MPEG-1?
MPEG-2? FLC? Or does your client intend to use a streaming video

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?

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

What is the lossy factor that your client is using for these

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

Hope this helps.
