Camera recordings are flickering?

[Nate1n22]

I just noticed on two of my cameras that continuously record, the video is flickering. I am using AnyDesk to remote into the software, but checked on the actual Blue Iris PC and it's doing the same thing..
Any ideas what could be causing this? I attached a video of what it's doing

interesting. trying to think what that might be.
how hard is the camera working?
like FPS and stream settings.
almost looks like the cam power wires are solid( not rebooting) , and the video/ data wires are glitchy somewhere. damn Rodents / damn rain, dammit all.

15 FPS for all cameras. The strange thing is, the live view in UI3 is fine. The camera preview in Blue Iris is good too, until I go back in my recordings, then it starts flickering

perhaps playback performance is lagging somehow.

I have had several BI boxes. (4) the first one an Opti i7-3770, (4 core 8 threads) had playback glitches and freakouts until I split the recording work onto to 2 disks. which spread the work around, freeing up resources to " playback" stuff while still writing 15 other data streams.
but the latest machine i7-8700 (6 cores 12 threads)can do 11 cams and playback all on 1 drive. with a 7200 rpm WD purple surveillance drive.

i'm thinking about bottlenecks for data..... but anyway.....if UI3 can do playback glitch free, maybe it's because it uses a lower resolution packet stream and a full rez stream drops frames or something along those lines.

Have you tried deleting the flickering camera from BI then re-adding it?

2 possible causes I can think of would be bottlenecks or interference.
