I have a few Atem TV Studios and I love the size and most options. I am having a problem getting any Macintosh computer to recognize it and output on HDMI. I have tried setting to 720P- 59.94 and 1080i 59.94 and neither one of them will work. Anyone else having this problems? Very frustrating that I cannot get Macs to connect but can get PC's and my cameras to work.

Love any help and feedback from anyone else having this issue.

So I did some more testing and this seems to be a problem with the HDCP handshake between the ATEM and Macs. Anyone else having this issues?

I had an issue with some of my Mac minis a few years ago. you would set the output for 59.94, yet the graphics card would really be outputting 60. even switchresx could not produce a true 59.94 output. in both cases the Mac stated it was sending 59.94, but 60 is what appeared at the output. a decimator md-hx was the final fix.

found a pix, shows Mac set to 59.94 but converted SDI output actually 60...a frustrating issue

this is 100% a mac software problem ... run boot camp on the same mac no issue at all not a hardware problem ... very very frustrating for apple to have limited their software's flexibility in this manner.

I believe this can be corrected by sending the Mac HDMI output through a Mini/Micro Converter.

Connect the Mini Converter, enter Display Options, "Collect windows" (not sure what the english version of OS X says here), set the Mini Converter output to your resolution and frame rate. Has saved my ass a few times to have an extra converter laying around.

Of course, I'm in Europe and using 50fps, not 59.94, so YMMV.

I am using a software called switchresx. Works like a charm on my MacBook Pro. You can choose any output resolution you can imagine.

Marco,

You say you can get any resolution out? Can you get 1080p 25 out? I Can't.

PC's Mac's they don't go that low as 25P.. Those videocards are build for 50+ FPS.. and rather 70/80 /120 Fps then 25..

If you want to run your atem in 25 which will introduce more problems.. Then you need a converter between your PC / Mac and the switcher.. something like a Decimator MD-HX.

Hey @xtreemtec, Could you help out. I'm trying to figure out settings with ATEM and Camera Control.

Why do believe 25p causes more issues?

Firstly I was setting up the BUMPS as 1080i50 to work with the ATEM and macs etc. When I connect the BUMP's to the TVSHD, the camera control software seems to override the camera settings. Now when I look at camera the shutter angle changes to 360 on the camera from 180. Is this right?

I want to be able to take the recorded footage later and pop it onto a 25p timeline and sync with audio recording from external recorder if I need to fine tune a HD version of the live broadcast for arching and sharing with clients.

Yes this is normal behaviour.. The Atem is always Master if you connect it. And will overwrite ALL parameters that are set in the camera.

So every setting will then be controlled by Atem CCU control.

I bought a Datavideo DAC70 converter.
Needed to run ski about 75 feet from podium laptop.
worked perfect.
