I've been playing with frame rates between 15 and 30. Because of speed
limitations of my little capture device, I found anything above 15 (half NTSC)
and under film (24 fps) results in the fewest dropped frames. I captured a
12000-frame clip with less than a 1% drop rate. The file converter I found
yesterday is really impressing me. The image quality is ever so slightly softer
than the Mpeg (which I think actually made it look better, not as grainy) and
the file size was cut by more than 50%.
This clip for example:
http://www.walt-n-ingrid.com/video/dakclip05.asf = 23.4 MB (24,580,510 bytes)
Same clip in Mpeg 1:
http://www.walt-n-ingrid.com/video/dakclip05.mpg = 68.0 MB (71,385,185 bytes)
Here are the other clips I captured so far.
