Validation tests on Atem mini Extreme output video level.


I Have configured Inside OBS the Blackmagic Intensity Pro 4K (HDMI) and in parallel on the same canvas the USB Video Class (UVC) protocol ATEM USB video Signal.


Very BIG Test Validation Discovery:


1. HDMI Outputs 1&2 - YUV 10-bit/8-bit 4:2:2 [LIMITED VIDEO FORMAT - mandatory], if you set it as Full Range it is Milky



2. Elgato Cam 4K capture card from HDMI to USB3.0 it offers (UVC) Protocol in uncompressed protocols NV12 8-bit 4:2:0 and YUY2 8-bit 4:2:2 [LIMITED VIDEO FORMAT - mandatory]


...

The 1 & 2 options are keeping the original HDMI audio channels.

...


In this case the capture devices offer identical to HDMI output original signal quality.

PS: Not through Elgato Virtual Camera, but through direct access to the Cam Link 4K.


!3. (Not shown in the video) USB protocol ATEM USB video Signal (MJPEG) - 8-bit 4:2:0 [FULL RANGE] if you set it in Limited Video Range it crushes the blacks and the whites


...


If you use a splitter on the HDMI output, the HDMI signal from YUV 10-bit is preserver with short high quality HDMI Cables, or transformed into RGB 8-bit always Limited Video Range with 15m HDMI 8K cable without audio.

(At least in my case with Ezcoo Splitter)


In this way you have similar gamma range and colors.


Live Streaming, from two parallel HDMI output signals from Atem mini Extreme into OBS, upscaling it from 1080p 25fps 10-bit up to 2160p 25fps 10-bit 4:2:2 H.264/H.265 - Rec.709 Limited Range, Colour format - P216 - 16-bit 4:2:2 - with only 5.4Mb/s in upstream.
