Help with Magewell USB Capture HDMI 4K Plus in Resolume Avenue

[Lumenarius]

Thanks again Zoltan.

I would classify it as going blank. Just a black screen. Not the "no signal" display either. Just blank.

The USB Capture Source is still present as a clip but it is missing the resolution and is just blank/black. Not sure if that helps classify the issue. See attached image from client. This is what it looks like after re-opening Avenue and encountering the issue.

As for restart that is more rare, sometimes about once a week. Else, they just close the applications and then open them the next day.

Doing a proper shutdown at the end of the day might be an idea to try.
Drivers and software can get confused when running for a loong time.

Thank you for the continued tips.

However, given this has been tried, and the error still persists, and is having to be dealt with multiple times a week, I don't think that is the core issue.

I have overseen installations that run continuously for weeks and the show file did not ever "decay" or cease to perform correctly.

I am just to suggest what I would try in your situation.

Have you tried to create a new admin user on the mac studio and check if other programm are running in background (like madmapper, since I've seen it in the dock another workaround could be capture throught it and sending in ndi to resolume, if the card remaing stable in madmapper, it's just a one shot solution but it cannot be definitive since it will introduce lag and couldn't be client friendly but it's a test i would ran to to limit the issue)

It's the same happen with Arena? (try the demo version and see if the behaviour is the same)
(I know that the driver are the same etc... and it doesn't make a lot of sense, but sometimes most of the solution doesn't or at least I cannot explain why if I do everything correctly it doesn't work while if I some changes I've made sometimes that shouldn't be related it, as read in the manuale and from the common knowledge, that's why I know it's science but sometimes I like to think more as alchemy )

Is the device getting hot? If it is try putting a heatsink on it. Can you try a different device (or the same device but different one) ? It could be a hardware problem

I´m having a similar / the same issue with a Magwell USB Capture HDMI interface. Many times when I reopen Resolume, the icons for this source are grey instead of green and do not have a connection to the USB Capture interface. I usually go to "sources", select the Magwell icon and drop it onto the grey icons. Effects and Midi controllers remain, just the source is somehow "updated". Really annoying, especially when you have many instances of this source but for me the only solution.

Could there be a ground loop happening? I had a capture card go down when a bnc plug touched some ducting which was grounded elsewhere, in that case, it was fatal to the hardware, but maybe a lower voltage difference but be at play? Is the output of the server eg the led rack/video processors/projector on the same ground?

Thanks for chiming in Cat.

I honestly think this is a factor for there is a serious static electricity effect happening at this venue.

It's all on astro turf, on a roof, and everyone is discharging static electricity when they touch anything metal.

We have been told the electricians have looked into it and there is nothing to be done.

The only other electronics that have issues on site are the speakers which have a very low hum and no "ground lift" devices have been able to fix that.

As of right now we are having the client simply reset the comp and drag in a new USB Capture Source onto the deck and it seems to work fine.

We may upgrade this in the future to another capture device but that is where it is at now.
