Hi all, I just picked up a used ATEM Mini (as we can't really wait the 4 months or whatever the timeframe is for the next production batch to hit the market). The unit came with everything and appears flawless in condition, not a single scratch, not even around the power jack.
When I plugged it in via USB, the PC saw it and when I connected to it in the ATEM Setup software it updated the firmware without issue. I did this yesterday, so it's the 8.2.3 version of the software. (Although it did remove/corrupt my install of BMD Media Express - that's another battle)
I am having an issue with the USB video feed - it's flickering some sort of scramble every couple of seconds. I've tried 3 different cameras/cables coming into the ATEM, and I've tried setting the source signal of the camera to several different qualities - although I'm not sure the ATEM is actually registering those changes as I'm not power-cycling the ATEM after switching.
Camera 1: Canon G10 HDMI Cable (25') -> ATEM
Camera 2: Canon G10 HDMI Cable (35') -> ATEM
Camera 3: Sony CX240 HDMI Cable (10') -> ATEM
Previously the cameras were plugged into the now-ancient BMD Decklink Mini Recorder 3G for a couple years now with these same cables. (I have 3 cards in my pc) I unplugged one of the G10s from the PCI card and plugged that camera into the ATEM. The G10 was previously outputting a 1080i @59.94 signal (as that's the highest the Decklink 3G will take). I did not set it manually. The ATEM saw the signal and I can ingest it in OBS, but immediately noticed there's a scrambled flicker that's happening every second or so. I thought maybe it was because it an interlaced signal and not progressive, so I grabbed a CX240 (where I can set the output signal manually and easily). I tried setting the signal from 1080i to 1080p, but the flicker remained. I swapped to a 720p signal, same thing, still with the flicker. I tried moving the cable to Input 1, 2, 3, and 4 on the ATEM (powercycling each time) - no change.
I tried setting the ATEM's output to a variety of framerates, though none of the changes made any difference to the video being capture.
Flicker example and some troubleshooting using the CX240: My account is too new to post urls, I'm assuming, but you append /watch?v=C-iqQRHT0Do to youtube's homepage url you will get the video
I tried swapping to a different USB port on the PC, but no change. I used USB 3.0 ports on the PC even though the cable is a 2.0 version. I did not try connecting to a 2.0 port (yet).
So here are my questions:
Is it possible the 2.0 USB cable isn't fast enough for the video? (I've ordered a 3.0 version to test)
Is it possible the ATEM really just doesn't play well with interlaced signals?
Is it possible I bought a defective unit?
Is it possible the ATEM really doesn't respond well to longer HDMI cables, even though 10' should be well within reason?
It took some convincing to get approval to buy this and you can imagine my heartbreak to see such a poor first impression.
As my 3G decklinks won't read the 1080p output from the HDMI Preview out, I was unable to test that method - but I ordered a Deckink 4k last night (and a cheap HDMI -> USB capture device which will arrive much sooner) to test that output to help narrow down the issue.
If anyone has any thoughts or similar experience, please share them.
Thanks,
John
