Forgive me if this seems like a noob question, but I recently purchased a PiCapture HD1 which I’m running off a Raspberry Pi 3B+ running a fully updated/upgraded Raspbian, and I’m getting odd screen tearing and replication (attached image as example).
I’m using the command raspivid-md 1 -awbg 1.0,1.0 -awb off -ex off
Anyone have any input that could help me?

It looks as though the input video signal resolution is lower than the resolution expected by the GPU for “mode 1”. If you are not sure of the input resolution, you can use PiVideo with the command “pivideo -q all” to see what mode is detected by the PiCapture board.
The “tearing“ you are seeing is actually junk from the video buffer because not enough data is received in a single frame.
Actually, I’m now getting a cleaner version of the video, but the colors are somewhat off and the screen is split down the middle and inverted (see image). I’m using the correct settings for 1080p mode 1 (all 4 lights are lit up with the last one flashing) and am getting what you can see below.
