This is reposted from net.video, in the hope that I'll get some more responses.
I would like to know if it is possible to make animated videotapes
using (computer) equipment that is not capable of generating the cell frames
in real time. This is the only scheme that I have been able
to come up with: (please excuse my gross ignorance of videotape technology)
Generate screen.
Start recorder, let it get up to speed.
Lay down special "frame packet" data.
Switch recorder input to generated screen image.
Stop recorder.
Are there services which can accept a tape made this way and build
a continuous videotape from the sequence of screens? What would
it cost? Can the "packet start" data be done machine-readably,
so that the process can be done without a(n expensive) human operator?
Are there in fact single-frame recorders? Good ones?
Thanks in advance,

x To generate by computer when the frames cannot be produced in real time (i.e., 30 or 60 per second), any of the following methods can be used: . animation video recorder (records frame at a time) . film camera (followed by high-quality transfer to video) . multi-frame digital frame store (expensive) . continuous recording followed by (tedious) editing . magnetic videodisk (like the instant-reply widgets) These are the ones I've seen or used; there no doubt are many more. Of these, the best result on lowest budget was the film camera: we set up a spare i/o port to crank the shutter so that the whole thing could be set up and left running. The video transfer and film are both expensive, but are cheaper than renting the animation recorder. Finding a framestore that you can hook up to is rare - most tv stations don't have multi-page ones, and the production houses that do want too much per hour - plus, how do you get your computer over to their facility? The videodisk works well but are hard to find - they aren't real common in tv stations, and only a few post-production houses have nice ones. Best of luck! -- -Brian Kantor, UC San Diego Kantor@Nosc ihnp4 \ decvax \ dcdwest ----- sdcsvax ----- brian ittvax / ucbvax/
