Someone else will need to hop in for the UI3 stuff. I only use it infrequently.

So... maybe these camera's implementation of H.265 is flawed (I saw that because their own web display does not work)? The problem is Blue Iris and a horrible implementation of H.265 decoding with or without QuickSync HA support..., and even being able to handle main stream 4K in H.264 at any respe...

More details about the current hardware would be helpful as would additional detail about the camera configurations. Try the cameras at their default settings with VLC viewer on a different machine if possible. If that isn't possible, shut down Blue Iris and try VLC on the same machine. Direct to di...

There may not be much load on the GPU. You select 'Intel' as the hardware acceleration preference in the Cameras tab of the main BI settings window. Then select 'default' for 'Hardware decode' in each camera's video configuration. You can alternatively leave the blanket default entry in the main BI ...

Open Task Manager and check the Performance tab for both a CPU and a GPU. If there's an active GPU, QuickSync is enabled. The BI Status window will also display an 'I' in the HA column if Intel is selected as the default processor and/or either 'Default' or 'Intel' are selected in the camera 's Hard...

There are a couple ways to do this. The simplest is probably what is shown below. Record Schedule.jpg The normal green active Profile 1 is the period of recording by virtue of the Record settings of the camera if it is set to record. Just schedule the desired start and stop time points accordingly u...

Pogo will be displeased :lol: To the contrary, I'm delighted the OP has arrived at a solution for his particular issue. Trust me, I share his frustration, albeit at the other end of the stream in the 4K UHD realm rather than the sub stream..., with a 22 camera system, not just 2 cameras running wit...

Task Manager is your friend.

Because during my own personal fault finding, I found BI5 gpu acceleration to be highly sensitive to drivers, making it the first thing to turn off while fault finding trying to find the problem. I think that's a reach even by the most diehard BI purists. Sensitive to drivers? But I'll agree with t...

I would tend to agree..., not the hardware, anyway. Drivers, maybe. BIOS, highly unlikely. Configuration, probable. I guess my main question would be why all the attention being paid to the sub stream quality in the first place if the main stream is performing as it should..., which I personally fin...
