Blue Iris

Hi All - I'm new to Blue Iris and I'm looking for some guidance on recording settings. I have recently purchased a 4K IP camera and am not concerned about disk space. What Blue Iris settings will give me the highest quality 4K recordings? I'm looking to maximize captured detail should I need a security related screen shot from the recording in the future.

Thanks,
Tim

Use the highest fps rate the camera allows, in both the cameras gui, then it will be picked up in BI. You can also adjust keyframe.
The fps of the BI interface (Live preview rate) is NOT the fps of the cameras. You can set this lower to save some cpu.
You may not be concerned about storage, but cpu may be an issue, unless you have a super-desktop.
