"video/audio capture and more"

[Sivakatirswami]

Aloha Paola:

After further research on the matter we are going to get (got one...  
testing now) a scan converter (hardware)  that takes a DV signal from  
any source and outputs to any destination. to capture both visual and  
audio for a rect of say 800 X 600 pixels with any quality, for say..  
20 minutes... you are talking about a *huge* amt of data and CPU  
power. I talked to the senior production manager at Total Training in  
New York (we use a lot of their CBT DVD's) and after describing our  
needs he said that tools on-board tools just won't be able to handle  
it. They use a $25,000 scan converter there (Yikes! not in our  
budget) but he had some other recommendations for <$1,000.00 that he  
said would do well

Apple Education recommended a Canopus box <$500.00 if you can qualify  
for edu, which we do... but we are not very happy with the output and  
just in the middle of R & D on this whole thing...but the concept is   
marvelous, you plug your computer into the box, run your  
presentation, and the output from the box goes to a DVD recorder (or  
anything else you care to wire  up... )

Changing the audio codec doesn't get you much... in experiments with  
QT here, 80% of the data is in the video stream, at least with my few  
tests, but I'm no expert... we are kind of fumbling along with this  
research. If anyone can chime in here that  would be great.

It would really be a huge feature bump if Revolution could actually  
dump to QT run time... but, I think, as I often do, that I'm asking  
for moon cheese.
