BMMCC HDMI outputs

I have ATEM Television studio and wondering if BM Micro Cinema Camera outputs 25p thru the HDMI signal to my ATEM?

Yes, If the Micro Studio or Cinema Camera is set to 1080p25, it should output this resolution on both HDMI and SDI.
That said, not sure why you want to use HDMI to the ATEM. HDMI is designed for monitoring on the Micro Studio, and the SDI out is the preferred connection to the ATEM, as it is a clean output. HDMI is only HD out, SDI is UHD and HD, on the Micro Studio. Also, HDMI is limited to a 12 to 15-foot cable length.

Thank you for answear!
I have 2 mini ursa that have SDI output so i can control them and get a good signal to ATEM.
But Micro Cinema Camera has only HDMI outputs. I'm going to buy that camera for Other Use, but want to use the camera with ATEM sometimes for an extra camera angle and then the project is set to 25p in the television studio. I had some trouble with Sony AX1 to output 25p thru HDMI, only got 50p from that cameras out signal.

Oops! my bad, was thinking yiu were using the Micro Studio. The Micro Cinema Camera can be used for live streaming, but would not be my choice to match with Ursa Mini, unless yiur are recording and not live streaming, so you can color correct the cameras to match. For live streaming, I would be using the Micro Studio Cameras.

To get a longer line feed to the Micro Cinema camera, yiu can add a Mini or Micro HDMI to SDI Converter, and send the ATEM a SDI that way.
