MBP 13" to Hyperdeck Mini - Signal distorted/flickering

I just bought 3 BM Hyperdeck Studio Mini .. i want to record the Output of my Macbook Pro 13" Late 2017 (Taskbar Version).

I use a USB-C to HDMI Adaper which goes to a BM MicroConverter HDMI to SDI which goes then to the Hyperdeck Studio MIni.
Everything brand new.

The problem is that the picture which arrives at the Hyperdeck is totally distorted and flickering = not useable at all.

Is there a known issue with MBP 13" with new intel graphics? (Intel Iris Plus Graphics 650 1536 MB)
or USB-C?

Because i tested the same configuration on my old MBP 13" (late 2011) with Display Port Adapter and it worked just fine.

Thank you

Are you using an original USB-C to HDMI adapter from Apple?
I have seen other brands fail hard on Decimator and BDM gear.. So make sure you have a official Apple converter.

Also what resolution are you using? Try a different resolution like 1280x720 and see if this makes a difference.

yeah i used the original from apple .. as well as two other brands ... same result

i also tried various resolutions .. same result

i guess the new 13" Macbook Pro just does not work with the Hyperdeck Studio Mini .. or the MicroConverter HDMI to SDI.
If so, they should write it on their homepage.

It's not BM. Apple has gone HDCP crazy with the newer models. I can't even get HDMI to work reliably to an Image Pro II without having to use DVI from my touch bar 15.
