I was able to export normally with 5.8.9.0... set export start and stop points, then export as MP4, default preset...

Yes, they are all visible in the recorded video files when playing back Alerts. I can see them on live video and recordings on UI3 too. I note I have "Burn label mark-up onto Alert images" in camera settings/Alert/AI. Could it be that ? and the answer was: image.png (both were NOT checked...

I also have burn label checked. so something else, sounds like a quick ask of Ken:)

Thanks...

Tim: I checked further and none of my added overlays show in my timeline view or recorded files (including a date/time overlay). So the %003 is acting the same as the date/time overlay. Viewable in live view, not recorded.
Do you see any of yours in your recorded files (or timeline view?)

I added %003 overlay txt macro and it shows in the live view, but it does not show in timeline or recorded file. Is there a setting to have the overlay show in the recorded file?

I had the same multiple Onvif "Events: Request 8000ffff" at exactly 3am, on most but not all cameras, but recordings were not impacted.
BI 5.8.7.11 and cpai 2.5.6

CPAI 2.5.6 posted, installed ok on win 10 and win 11, and seems working ok.

how about in BI's camera settings, video tab, Video tab, click on configure, do you have anything in the Audio Stream Profiles? Mine is "64kbps G.711 u-law"

If you right click on the camera's display in BI's main console, do you see "Play Live Audio" as the second item under camera settings? If so, is it bold (enabled)??

make sure you have "Enable Pan/Tilt" etc checked in the "PTZ/Control Tab" in each camera's settings in Blue Iris.
That enables the zoom for varifocals in BI live view screen.
