Video signal help

Hello,

I recently switched from a SP F3 FC to a F4 Flame AIO FC (https://www.banggood.com/F4-FLAME-Race-Spec-STM32F405-Flight-Control-Built-in-BETAFLIGHT-OSD-5V-BEC-PDB-Current-Sensor-p-1136917.html) and noticed that my video signal starts breaking up a lot closer than it used to.

I'm using the same VTX, camera, and antennas. I soldered the VTX to the dedicated Signal, VCC and Ground pins and the camera to the dedicated Signal, VCC and ground pins on the FC.

Is there anything else I can do to try and troubleshoot this or get it better?

Thanks for your help!
