Bizarre Zenmuse BMPCC issue

[Mister Flibble]

Hello all,

I';m wondering if anybody else has encountered this problem...

S1000, A2, Blackmagic Pocket Cinema Camera and BMPCC Zenmuse. All firmware is up to date and I haven';t done anything silly like leave the HD/AV switch on HD.

It all works fine, except for the HDMI feed on the Zenmuse when initialising with the BMPCC.

If I turn it all on with the BMPCC attached: Video is a blank white screen.
If I turn it all on with my GoPro Hero 3 attached: Video feed is fine.
If I then disconnect the GoPro and attach the BMPCC: Video feed is fine.
If I then recycle the power (essentially back to step 1): Video is a blank white screen.

Frankly, it';s driving me up the sporking wall.

Any thoughts?

Cheers, MF.

Thanks to a helpful chap on another forum, I checked the frame rate on my GoPro (25fps), set my BMPCC to this... And lo! There was video!

I';ve been through all the camera frame rate settings, and 25, 29.97 and 30 fps all work but the others do not. I feel that DJI should probably tell us that the zenmuse (for whatever reason) requires a certain frame rate to get the system going.

Seems to be a common issue shared with the GH4 gimbal as well...  couple of people posted they thought it was a temperature issue.. but not convinced.. my issues only started when I upgraded the HDMI board to latest firmware ver..  DJI sent me a replacement board and cable.. but was still the same..

Latest firmware for GH4 seems to have improved the problem for me at the mo..  .. but as you say I think the issue is due to compatibility issues with sync rates...
