Hi folks,
Sorry for the long and detailed post. I'm testing out an ATEM 1 M/E Production Studio 4K with the Advanced Control Panel and a SmartVideo Hub (20x20). All are brand new and I'm tracing down some PC and camera video compatibility issues. The ATEM 1 M/E is set to 720p59.94 and the Smartvideo Hub is between sources and ATEM so shows the incoming video resolution regardless. For testing I'm using the following inputs/converters:
Canon HF Vixia R600 (similar to church's Canon HF Vixia G40's)
Cisco Precision60 (our "Skycam" dedicated to the external Recording Room to see the overall stage)
Acer Netbook
So it appears that no 720p60 (or 1080p60) source is compatible with the ATEM 1 M/E 4K, only 720p59.95 and 1080p59.95 video sources. The spec's back this up, but I find it odd that every outboard converter and hub/matrix that BMD has supports both p60 and p59.94 times, but all of their ATEM switchers only support p59.94 (in this case, anyway). I would have expected the Cisco camera outputs to be video timings, but apparently they're computer timings (p60) as well, maybe because they're designed for VTCs. So the followup question would be, how do I get computer timing inputs converted to the apparently video-timing-only ATEM?
The other thing I don't understand is why my PC HDMI output, which shows up as 720p60 on the SmartVideo Hub, works at all on the ATEM 4K's HDMI input if it's only supposed to be able to accept video timings? Unless my netbook autodetects the destination and sets it to computer or video timing as appropriate? Windows 10 shows it as 1280x720@60Hz 8-bit RGB, though, which is a computer timing.
If you read this far, thanks. Hopefully there's a solution out there...upgrading from the ATEM HD 1 M/E to the ATEM 4K 1 M/E gains me 2 additional SDI inputs, which is nice, but I lose all but one HDMI inputs and have need of at least 2 PC inputs (plus will have to extend even that one HDMI input with a pair of HDMI/SDI, SDI/HDMI micro converters since we're supposed to be moving the video equipment out of our booth and to a nearby equipment closet...
Thanks,
Jeff

Canon HF Vixia R600 (similar to church's Canon HF Vixia G40's)
- 1080p HDMI output to BMD HDMI/SDI Micro Converter
- BMD HDMI/SDI Micro Converter output 1 to SmartVideo Hub. Appears as 1080p59.95 on the SmartVideo Hub, doesn't show on the ATEM 1 M/E LCD screen obviously, just used to see what's being fed to the UpDownCross converter.
- BMD HDMI/SDI Micro Converter output 2 to BMD UpDownCross Mini Converter set to "720", then to SmartVideo Hub. Appears as 720p59.95 on the SmartVideo Hub and shows on the ATEM 1 M/E LCD screen fine. (NOTE: the UpDownCross won't be necessary at church as we can hard-set the HDMI output to 720p; the R600 auto-sets so when it sees the HDMI/SDI converter it sets the output to 1080p)
Cisco Precision60 (our "Skycam" dedicated to the external Recording Room to see the overall stage)
- 720p60 SDI output directly to SmartVideo Hub. Appears as 720p60 on the SmartVideo Hub, doesn't show on the ATEM 1 M/E LCD screen.
- 720p60 SDI output to BMD UpDownCross Mini Converter set to "720", then to SmartVideo Hub. Still appears as 720p60 on the SmartVideo Hub, doesn't show on the ATEM 1 M/E LCD screen.
- 1080p HDMI output to BMD HDMI/SDI Micro Converter.
- BMD HDMI/SDI Micro Converter output 1 to SmartVideo Hub. Appears as 1080p60 on the SmartVideo Hub, doesn't show on the ATEM 1 M/E LCD screen obviously, just used to see what's being fed to the UpDownCross converter.
- BMD HDMI/SDI Micro Converter output 2 to BMD UpDownCross Mini Converter set to "720", then to SmartVideo Hub. Appears as 720p60 on the SmartVideo Hub, doesn't show on the ATEM 1 M/E LCD screen.
Acer Netbook
- 1280x720@60Hz HDMI output to BMD HDMI/SDI Micro Converter to SmartVideo Hub. Appears as 720p60 on the SmartVideo Hub, doesn't show on the ATEM 1 M/E LCD screen (Input 1 set to SDI).
- 1280x720@60Hz HDMI output directly to ATEM 1 M/E HDMI Input, bypassing SmartVideo Hub, shows on the ATEM 1 M/E LCD screen fine (Input 1 set to HDMI).
So it appears that no 720p60 (or 1080p60) source is compatible with the ATEM 1 M/E 4K, only 720p59.95 and 1080p59.95 video sources.
