Just finished installing a new Windows 10 Pro PC that was built by third party (Safe Harbor), vMix and BM Decklink Quad 2 and RTX 3070 Ti pre-installed. 32GB DDR4 3200 RAM, i9-10900X, 2 SSD drives, 1 10TB hard disk, ASUS Prime x299-A II MB. Added an Elgato Cam Link Pro for 4K input. RTX in 16 slot, Duo in second 16 slot, Cam Link in 16x8 slot. 48 lanes available, 28 used.
2 - 4K cams (Sony ZV-E10) into Cam Link, 6 - HD (1080i) cams into Duo, one HD output from Duo to Atomos Inferno external recorder. 1080i cams converted to 1080p30 in vMix. Project 1080p30. Recording to HD FFMPEG on SSD drive.
Did installation and testing over 5 days, had all the cams hooked up for at least 2 hours at one point, thought all was good. Then, when I went to do a show, about 45 minutes in one camera on the Duo froze and dropped, I couldn't get it back on. Switched to used a different cam on a different channel on the Duo, after another hour that dropped to a very slow (4 fps?) frame rate, then it froze as well. Final 30 minutes switched to a third of the 8 total cameras, that one remained for the rest of the session. At the end, therefore, I was only running 6 cameras, two of them on the Cam Link card, so only 4 on the Duo (plus the output, so 5 total).
Check temps, all hardware within range, nothing over 70°.
Am I missing something here? Didn't need to install any special software to have the Cam Link recognized, and the Duo was installed when the PC was built. No errors showed that I could see. From what the builder says and my research, this system should be plenty powerful enough to handle all of these inputs, it should be able to be saturated to 12 total inputs/outputs including both cards.
What should I be looking at for a debug? Anyone else experience this?

Eliot,
Did you ever resolve your issue? I am looking at purchasing a custom build machine from Safe Harbor. Looks like you purchased a Tsunami Riptide, any reason why you got a Riptide over a Surf? I can't tell if there is an advantage one has over another or why one would pick one over another.

Anyone else experience this? the mb/cpu duo should not pose any problems normally for the config  Capture d'ecran 2024-06-25 233910.jpg (45kb) downloaded 0 time(s). Capture d'ecran 2024-06-25 233950.jpg (71kb) downloaded 1 time(s).Are the SSDs in the m2.1 and m2.3 ports ? 36 lanes used with ssd It looks more like a configuration problem in vmix can be set the cameras to the same definition/frequency as the vmix project

I am looking for the same answer, I did find that I could get 6 cameras to work by moving the USB connectors to different places. If I used a USB hub then I could only get 3 cameras to work and if I moved 4 to the back usb3.0 and 2 to the front USB 3.0 then I could get 6 to work but if I plugged in the 7th camera then it took out two others and the seventh did not work leaving me with 4 useable videos. a couple of years ago I had cameras dropping out after some time and somehow did something to fix that but don't remember what I did... that may have been why I upgraded to Vmix 4K.
I have Vmix 4K version and running 5 - 4K cameras and one video monitor all using 6- AVerMedia Live Gamer Portable 2+. The cameras are 4K but the live gamer capture USB to computer may not be and the HDMI output of the camera to the capture device may not be 4K... But the videos recorded look to be ultra-HD. I record the sessions on the camera's SSD in 4K and edit the live stream using those cards later along with making DVD's of the sessions.
I am using a HP Pavilion Gaming computer with AMD Ryzen 7 2700 eight core processor 3.20GHz windows 10 and 6 SS-USB ports + 2 USB 2.0 and 1 USB-C 3.0 and have live streamed out to two different platforms at the same time. using over 70% CPU
I thought it might be something in Vmix program interface to the USB busses. Or limits on the USB busses in this system. Sounds like I am not the only one having this problem.
Back ground: I used to build High end systems for businesses and have worked on computer operated machinery as a tech until I retired. I usually don't give up until the problem is solved. I put this problem on the back burner because 5 cameras + 1 momitor are enough in the small space and only me to operate them and produce at the same time. It popped it's ugly head back up when I tried to add one more camera.
