H3-3D gimbal stops recording

[bzpop]

I have GP4 on H3-3D gimbal,
i fire it up, all is good, i have picture on my monitor, 4K 30, as soon as i start record picture on monitor gets frozen, record stops and camera goes to 'busy' mode,
this setup used to work well, i have fast card, Boscam TS832, i even replaced USB ribbon cable - problem is still there,
any ideas?
Thx!

Troubleshoot possible causes:

1. Try 1080p 30 fps

If that works without a problem you can rule out hardware.

I've heard with the Hero 4 Black that 4K 30 fps isn't supported with FPV. Try to reduce the frame rate if shooting 4K.

+1 On trying lower res.

try just recording 4k with the standalone Gopro.

and what speed is your card? You need minimum 60mb per second card (UHS 1 or 2) for 4k. Class 10 wont cut it.
