Hi all,
   I have an interesting question....  I would like to know if there is any
way to digitize video in real-time and do some special effects on the 
images for display as part of a psychedelic lightshow.....

   What I ultimately want to do is use a video camera and show the images
while creating real-time psychedelic special effects such as "trails" and 
"color distortions" on moving objets...

   Is there any way to do this kind of thing on a PC type platform?  Maybe
a high-end 486/33MHz with some video cards?

   I understand that IBM offers a video capture adapter - does this thing
digitize in real-time?

   How would you manipulate the images for these effects?  Are there any 
algorithms for this type of thing or possibly software packages that will
do video special effects like this?

   Any information that anyone could give me on how to do this or who I
could contact would be greatly appreciated....  Thanks in advance, Curt

What about the Video Toaster ? It has lots of hardware horsepower for
real time video effects that any general purpose CPU would have a very
hard time matching. I believe the Toaster software uses the Amiga's
inter-process communication and control language AREXX, which basically
allows you to control one or more programs from a script. For example,
it could randomly choose the video effect currently running.

The toaster's specs have been re-hashed many times, but basically you
can frame grab in 1/60th of a second, mix from up to four input video
sources, fade between sources, do colour effects, and heaps of wipes.
All this for $1600 (+ the Amiga you put it in).

I also believe it can be controlled by a PC, but what's the point ?
The Amiga's real time, multitasking OS would be just the shot for this
type of thing.

Regards,

Gary McGhee

If you want to utilize the full power of Video Toaster, I recommend
ShowMaker from Gold Disk.
