Video constantly freezes when recording church services

[dcrowe]

Looking for input on how to stop the video from freezing when recording
Current configuration
Optiplex 3050 w/ 16 gb ram
1 Terabytes of Storage
Windows 11, v24H2
Using 1 Vaddio Roboshot 12 USB & 2 Conferenceshot PTZ cameras
Been using this setup a couple of years but the freezing is getting worse
Just tried a Optiplex 7050 MT w/ 64 GB Ram , 1,5 TB of storage and still getting the same issue
not streaming just recording , also recording offline (connected to network but no internet)
cameras connected to a POE switch to get their IP for controlling via the IP interface
any suggestions

Your details aren't enough (like saying engine in inline 4 and not mentioning if a Prius or Porsche)
Model PC is nice, but CPU model makes WAY more difference.... are those using 8th gen Intel CPUs? and is that an i3, i5, i7? etc
Having storage is nice, but speed of that storage is what is important. Is that SSD storage, and do you have plenty of free space?
if recording to a HDD, and OS on same disk, you are quite possibly running into disk I/O conflict (the fix depends on what else is driving the I/O)... easy fix is to replace HDD with SSD

Sorry to hear you have already upgraded to the every-other Microsoft PoS desktop OS Win11 (though effectively required later this year). Anyway, there are LOTS of optimization steps to take to keep hardware resource utilization of the OS especially the eye-candy and ad-rich Win11 from messing with OBS Studio (ie reduce background process workload)

Are IP PTZ cameras video fed to OBS over network, or also USB, or HDMI? are you using an external video switcher, or all 3 videos visible simultaneously to OBS Studio?
Are you using OBS Studio Preview mode (with is 2X rendering workload)?

Using SSD but was recording and storing on same drive. built new pc with more than one SSD for the O/S and another to store the video on

PTZ are connected via USB and a POE switch, tried this past sunday during service to go either or and camera werr not seen strictly on USB even though i re-enable usb streaming and only could view ip streaming through the vaddio tool OBS did not see the cameras at all might be missing a plug-in not using external switcher yet trying to convince church to purchase camera package from local company

I have a SATA SSD for both Operating System and OBS Studio recording (on a 4+yr old Optiplex 7080 with an i7-10700K) and that is plenty of disk I/O (NVMe is great, but not required). I then have a HDD that I move recordings to for Archiving (I Record at 3X+ bitrate of stream). However, I know how, and have, optimized Operating System to reduce background workload (ie turn off a lot of M$ default crap)
if your PCs are 3 generations older... and lower-end CPUs (like i3 or i5), then quite possibly simply CPU overloaded. And Win10 support (security patches) expires this fall, so unless those are Win11 compatible (and I wouldn't count on it unless you check specifically for your exact CPU config), your are looking at switching to Linux or needing to get new PCs

You may have an issue with USB Root Hub overload with the cameras and possibly other inputs/devices (especially if mixing USB 2.0 and 3.x devices on same hub.
An external video switcher means OBS Studio would only see a single video feed (and never change)... as the switcher would change inputs. That means any transition effects need to be in the switcher. Sometimes an external switcher is necessary (and definitely greatly reduces CPU and other hardware resource demands on OBS Studio PC) but I personally prefer OBS Studio seeing all camera inputs, if at all practical (enables Picture-in-Picture, nice fades, etc)

I personally strongly prefer NDI PoE PTZ camera.. .single cable... easy peasy, and that means network traffic for video (not running through USB Root Hub)... but such cameras are more expensive...
