Hi, I work at a TV station were we use a very old Commodore Amiga 200HD to insert a text scroll over graphics. However, the Amiga's graphics card is going out and is now losing color. I have a Power Mac 7500/100 that has the component and s-video inputs on the back. What I would like, is to be able to pass a video feed through the computer live as the Mac inserts a scroll of graphics. Can I pass a live video feed and insert graphics with this Mac? If so, what additional graphics card an software will i need. Any help will be greatly appreciated. Thanks.
