I'm interested in creating presentation quality videotapes that utilitize real-world filming, as well as spliced-in computer graphics. Is this possible with an IBM-PC/XT/AT, and if so, what equipment would I need? Finally, how much would it cost (generally)? First off, let me admit my bias: I have consulted for USVideo, and I wrote the TSR software for their board. That said, I suggest that you get a USVideo Recordable VGA card, with overlay daughter board. That gets you a video-in, video-out system. You can do genlock, video-only, computer-only, and overlay. It sounds like you're most interested in the overlay feature. Basically, you select one of your colors to be the overlaid color, and wherever it appears on the screen (text OR graphics mode), you get your video-in signal instead of your computer display. The only thing you *can't* do with it is mix the two signals. You can't do, for example, a transparent cursor. I haven't found any problems with compatability, and when you run it in VGA-output mode (instead of NTSC-output), it seems to be no different than any other supervga board. -- --russ (nelson@clutx [.bitnet | .clarkson.edu]) FAX 315-268-7600 It's better to get mugged than to live a life of fear -- Freeman Dyson I joined the League for Programming Freedom, and I hope you'll join too.
