Hello,
I have a gopro live usb video out cable that I used earlier for my FPV airplane. I am having issues with my video TX so I wanted to solder a simple cable that connects my gopro to an analog (PAL) composite video cable for checking my video source and monitor.

I connected video to the center pin and ground to the shielding.
Am I missing something ?

 

You want to make one of these yourself?

Post 5 here might help?

 

Thx... It was indeed the gopro cable... Other video source worked flawless with selfmade servo connector to RCA cable...
