When i watch someone walk on the live video in BI desktop app there is a 1.5 sec lag or so but on the recording of the event there is no lag.

What is going on here? By lag i mean someone takes 4 steps then there is a sec or two lag.
 
Just to confirm you are saying that the live video feed is pausing momentarily every few seconds or every few minutes, does the clock also stop, is the clock from the camera or is BI inserting it. Does the clock pause even when there is no motion in the field of view. Are you using CPAI? What version of BI are you using? What are the specs for your system, could you have an under powered system?

No the clock does not stop, i7-14700K CPU is only at 10% 32GB of RAM 6GB only being used. Using the newest BI version. Also using a 10GIG NIC card and 10 GIG switch.
 
I take that back the clock does lag to. I am assuming the BI gets the time from my PC, i have never set anything for it.

It's easy to see the lag if you watch someone walk they take two steps then there is a slight pause and it just re-peats. And the recorded video will have no lag.

Watch the sec.

Not sure if this will make any difference, in the camera setting "Video" tab, click the configure button and try increasing the size of the receive buffer from default 6 MB to 8 or 10, let us know if it makes any difference.
 
I advise you to download PingTracer on the Blue Iris machine. This is a program that repeatedly pings network devices and plots the response time on a graph. In the Host field put in the IP addresses of some of your affected cameras (separate each address by comma or space). For good measure, also include your router's IP address and 1.1.1.1 (which is a public cloudflare DNS service) so that there is some non-camera stuff to compare against. Ping them at a rate of at least 3 pings per second (can go up to 10 per second but some cameras may not handle a higher rate too well). The response time graphs give a good picture of your network health. An ideal graph will be very hard to see because it will be all 0-1 millisecond response times on anything LAN-connected, and anything you have to reach over the internet (like 1.1.1.1) should have a graph that is easily visible but fairly steady and all green.

Then observe the ping graphs and the cameras at the same time. If spikes in ping response time to the cameras correspond to the live playback problems, then you know your network is not up to the task. If there are no corresponding spikes in the ping response time, then it is more likely a software/configuration issue.

ok so you guys see the seconds how they jitter or jump? The live video feed does the same on every camera not just one. Wireless and hardwired most all mine are hardwired.

I would be surprised if it's the network itself, i use all ubiquiti gear.

I would be more likely to blame windows 11 or a BI setting, i also don't know why the recorded clips don't have the issue. BTW my CPU usage is only 3%

I will try the ping tracer.
 
Did you try the buffer setting? Are the cameras using H264? What frame rate? Is the I-Frame ratio set to 1?
 
Also, are you viewing the BI console directly or via RDP? There's a setting for refresh under Blue Iris Settings > Camera > Video during Remote Desktop.
 
I turned on Hardware accelerated decode intel issue is now gone.

Not sure how that works and if it's different than intel quick sync. My BI pc does not have a dedicated gpu only the built in intel.
