Video recording options?

[Andy Rapo]

If you can display the stuff in real time then you can record it in real time.  The only reason I can think of to use a frame grabber is to do your recording in the background, or to store images that take longer than 1/30 sec. to draw.

We have a 4D220GTX and the VideoCreator.  It does a real-time conversion to NTSC/S-VHS which we record directly onto tape.  As long as our animations can play in real time, we can record them in real time.  So far, we've been very happy with the VC.

The videoCreator will also control your VTR decks allowing us to completely automate the recording process.  I've just finished an Allegro Lisp interface to the VideoCreator's functions.  This makes using the VC very easy.
