Hi guys,
I want to preview my video while I edit using the tv out on my radeon 9700pro. I have vegas 4. Is there a setting or a piece of software I can use/download?
Vegas will not output through your Radeon card. You need to use your Firewire wire connection. You can run the Firewire to your camera and then out to your TV.
I don't know if you can set your card up to act as two monitors and then move the preview window to the TV. I expect that the results would be poor.
Actually you can output through your Radeon card, but it is not the kind of preview you're thinking of, nor the kind of preview you want. You can basically set up the tv as a second monitor and then drag the video preview window over to the tv and make it the full size of the TV. It will work, but the preview will be absolutely terrible and will in no way reflect what your video looks like.
