For a back-of-the napkin calculation can we not assume that data equal
to the entire size of the file will be streamed to the client during
playback?  I understand that frame rate, etc. are important as well
but I do not need exact figures, just a general idea of what size
tube** is required on the viewer's side to see the video without
skipping.

Yes, you're right.  You did define the length of the clip, after all...:>

I'm just use to streaming wild, not off of an existing file.

That being said, you may want to look at H.264 as a possible compression codec. It looks pretty good. For example, on one of our streamers, we are streaming 640x480@24fps, using H.264 compression, and seeing the bandwidth usage fluctuating around 800kb/sec, depending on video content. The compression setting is "best", which means lightest compression.

(We use quicktime broadcaster to feed Darwin Streaming Server on a Centos 5.x box.)

Sorry I didn't pay more attention to the OP. I must keep my hands off the keyboard...

Later,

Monty
