OBS, PTZ Cameras periodically freezing during streaming.

I run a weekly Sunday morning Church service Stream with 3 NDI enabled, Network connected PTZ Optics Cameras. I have noticed a periodic and momentary freeze during streaming las week. They may freeze before streaming starts, but I have not noticed this. I am also using a MAC to run OBS.

Any Clues as to why this is happening?

What exactly is freezing

I can't answer specifically, but be aware the computer has to render all 3 video inputs. So I recommend monitoring hardware resource (CPU, GPU, RAM, Disk I/O, etc) utilization [Activity Monitor or similar System Monitor app] to see if your system is being maxed out (bottleneck) with your settings

Are you also recording locally? is that recording ok? and recognize locally recording adds Disk I/O.
It is possible that recording/streaming is okay, but the User Interface struggles to keep up... just depends.. Depending on computer, OS, OS settings, etc sometimes with an under-powered system (for given settings/workload) UI will lag before stream/recording does, sometimes it is the other way around.

But without a lot more details on your setup, can't really comment further other than following the pinned post in this forum would be a start

Please post a log with your issue! Here's how...

OBS Studio creates a log file each time you run it which contains very useful diagnostic information. Without a log file, it's much harder for any support volunteers to figure out problems and your post may be ignored. To upload a log file, go to the Help menu > Log Files > Upload Last Log...

. Though recognize that is OBS log only. Realize that such log won't tell us what else you have running on your system, and if any of that is interfering.

Thanks for your response!
My Setup:
MAC OS 11.6.2 Big Sur, 6 core Intel Core i7, 32 GB 2667 MHz DDR4, Intel UHD Graphics
I do not record or stream with OBS. Boxcast streaming.

I will employ an Activity Monitor this week. Good Suggestion.

Uh, what are you using OBS for then?
Are you using the Boxcaster encoding hardware? if yes, what are you using OBS for, of anything?
Boxcast (looking it up now) has their own encoding hardware, or you can direct stream to Boxcast from OBS.. so if you follow up, provide some more details of your setup, and what role OBS has

For MacOS specific feedback, posting to Windows OS support forum is probably wrong place, and you'll get better answers in the MacOS forum https://obsproject.com/forum/list/mac-support.33/

Side note: recognize that the specs you list don't really tell important details, like which generation CPU (it matters) [sorry, I'm not a Mac user, so I don't know if 6c i7 indicates which generation (the 1st 6c i7 was released in 2010, though DDR3, 6c i7 with DDR4 first available with Haswell-E in 2014, or maybe yours is 6th Gen Skylake (circa 2017) or maybe 8th gen Coffee Lake? Intel is on 12th generation CPUs today
Do you have the 2019 MacBook Pro?

real-time video encoding is VERY computationally demanding, which means depending on settings some laptops, with power and thermal limits, may struggle sooner than a similar desktop... but it depends on many factors
