Composite camera capture resolution?


I have NTSC composite cameras and a capture card. Works well since I upgraded to a BT capture board with one chip per camera.

I'm currently capturing 640x480. My camera has specs of 520 lines (probably optimistic). Am I gaining any resolution at all by capturing at 640?

Am I correct that 480 should always be used as the height to get maximum resolution?

Paste in your error messages, config settings, terminal window output etc in this text field.

Jon , you have to check your capture card specs ... but i bet that is adopted as standard for NTSC capture 480 horizontal lines, so it's max value for height

and 720 for width.

About NTSC video resolution ( 720x480 )

About lines of horizontal resolution ( TVL )

Don't forget this :
