Hi all. Long time lurker and Resolume user, first time I have an issue that I can't find an answer for in this forum or the docs.
It would take too long to fully describe the setup, but here's the gist: We're doing virtual events. We'll have multiple Zoom calls running on multiple computers in gallery view, which then come into Resolume via a Magewell Pro Capture Quad SDI. Each of these sources is then duplicated onto multiple layers with separate crop values, so that we end up with independent layers, each containing the video box of a single Zoom call participant. We can then move them around and add graphic overlays and underlays and such.
Most of the time this works fantastically well. But every now and then, the sources start flickering. The flickering is fast, maybe 1 frame at a time, and seems to happen across several but not all of the individual layers. It happens at a random, unpredictable interval, and sometimes is quick and frequent and sometimes is more slow and intermittent. But here's where it gets weird: rather than what you'd expect, where it would flicker to a black image or a white image or even a corrupted image of what it's supposed to be, what gets shown in the flicker is the video from a DIFFERENT input on the capture card. It usually seems to be the adjacent input, and is usually upside down. Sometimes we're able to get it to go away by manually changing the resolution or frame rate and changing it back, or by setting it specifically to its framerate rather than the auto mode. But it always comes back.
Drivers and firmware are all up to date. I've verified that there isn't an issue with the card itself by using a different software (OBS) to bring in the inputs and had them run for hours and hours with no issue. I know that this setup can work, because we will have very successful periods of time that this doesn't happen at all, and also because we have another location using the same Resolume patch but with a Blackmagic Quad SDI card instead and they don't have any issues with it.
If the answer is to just replace the card, I suppose that's what we have to do, but that thing isn't cheap and I'd really prefer to just get it happy since it works so well most of the time.
