I entered what I thought was the right info for recording 8mm video tape. Everything seems to work except I can't get the recording to use the entire screen. It shows up in one corner of the screen with a red box around it. Red line with "600 px" as well as another horizonal line with "1280 px". What setting do I have to change to have the video to take up the full OBS screen.
Your canvas is huge, compared to the actual resolution that you're capturing. You *could* right-click -> Transform -> Fit to screen, but that would create a much bigger file than you really need, for no real benefit.
Better to shrink the canvas to what you're capturing. Look at the Properties of that source, and (probably manually) copy the frame size into both boxes at Settings -> Video.
Also, there is static on the bottom of the video being converted. The original video does not have that bottom static line.
Actually, it does. The TV that it was meant to be played on, has enough overscan that it's not displayed - essentially it zooms in slightly and the opaque frame around the TV blocks it - but it's there.
There's probably some "static" at the top too. Whether you get either one, or both, depends on how the capture card handles the sync pulses that come from the tape deck. You *might* be able to adjust the sync alignment ("tracking") on one end or the other of the analog wire, and maybe trade the noise at the bottom for some more picture on top, or you might be stuck with what you've got. At any rate, you can crop it, and allow the cropped area to be replaced with black.
