GoPro Hero11 Black Video "Burn-in" Overlay Problem

[zeeedi]

Hello Everyone,

I have a new Hero 11 Black and I want to add the burn in overlay to my videos. I already installed the latest labs firmware for my Hero 11 and this is just working. For example the personalization info still works. Now I want to add the time and the date metadata in all videos but its not working. I got 4K resolution, 24 fps, 16:9 and 10-bit is off.
Can anybody help me?

Set you font to 30 pixels high and it should work. The fix for smaller pixel is still coming.

Thanks for your help so far. To reduce the file size I changed the resolution to 1080 and 60fps. After scanning the QR Code I get the time and date displayed just for a few seconds but I need it permanent. After choosing the option "Permanent Overlay" and scanning the Code again it didn´t changed to a permanent overlay. You know why??

[dnewman-gpsw]

Permanent just means it is enabled automatic at boot, and then they will be always on unless you used !MBRNT=x to limit the time they render into the video. If you don't use BRNT (burn time) the overlays will render into recorded video for the whole capture. The overlays are not displayed on the LCD.

Okay I understand the permanent isue (permanent=overlay is there after booting; not permanent=overlay disappears after booting). My problem is that the overlays are just rendered into the recorded video for about 5 seconds and then it disappears. It is not rendered for the whole capture. By the way I see the overlay on the LCD (for 5 secs) of my GoPro if I start playing the video direct on the GoPro and then it disappears too. My resolution is 1080p with 30fps.

PS: If I boot my GoPro, I got the message "OVERLAYS ACTIVE" and then "Features activated: BRNO=10 , BRNT=3600 , BURN"
Perhaps that´s the problem??

[dnewman-gpsw]

BRNT=3600 is the issue. There is a bug, so that 3600/(900) = 4 seconds (+1). So set BRNT=0, for unlimited. If you really want only an hour, set BRNT=3240000.

[zeeedi]

Perfekt. Can you explain me how to set BRNT=0? I don't know how I activated the above mentioned Features.

I think I found it:

I can try it tomorrow. But I don't know yet, how it was activated.
Correct?

!MBRNT=0 <- as a QR code
