Because the HDMI output of our receiver didn’t support decimal point frame output, it will automatically convert it into integer frame video output.

All Micro single/SLR camera, only one of  HDMI video output and camera’s screen display can be enabled  when you are recording 4K video because of the limitation of the camera itself. so you can try to set the shooting format as 1080.

But Photo-graphy/Video camera does not have this limitation, it support HDMI video output and camera’s screen display simultaneously.

If you insist to use Micro single/SLR camera recording 4K video and monitoring the shooting simultaneously, please connect Camera->ATOMOS Recorder->Transmitter.

Because of the video format of BMD SDI input support up to P59.94, please set the video format to 1080P50/i50 on the camera side.

Please do the camera HDMI settings as below:
1. Change HDMI output format to 1080p/i (Not recording format)
2. Set HDMI Information Display to “OFF”
3. Set HDMI Control to “OFF”

Actually the HDMI input port 1 of ATEM mini only support RGB mode and our device output is YUV format. That is why the the image turns green, its compatibility issue. But Port 2/3/4 of ATEM could works fine.

Issue phenomenon:

Please close the 3D-LUT function in the monitor and recheck.

At present, the UVC function of the C1 does not support the 1080i format. You need to change the output format of the camera to the 1080p format. The SDI and HDMI interface 1080p and 1080i formats of the C1 are supported, but only the UVC output does not support the 1080i format.

Astro Boy Recorder has set the problem of recording ProresRaw. If you change it to ProRes, it will display normally.
