Event firing, alarm frames present, but video missing movement

Not sure what is going on here, but I've got a camera set up with the following buffer config:
- 2022-08-04 09_30_53-MeadowCourt - Monitor - 23 Springdale - Garage - Brave.png (13.41 KiB) Viewed 3315 times
It is correctly generating an event on movement with the shown alarm frames etc:
- 2022-08-04 09_32_37-MeadowCourt - Event 668617 - Brave.png (18.66 KiB) Viewed 3315 times
I can see the vehicle in the alarm frame:
- 2022-08-04 09_34_10-MeadowCourt - Frame - 668617 - 1 - Brave.png (410.26 KiB) Viewed 3315 times
The video shows the alarm as red in the timeline, but there is no vehicle recorded at all.
Any thoughts on what might be going here?

Could not attach a screenshot of video showing no vehicle in the original post, so followed up here

Hello,
I'm having the exact same problem as you had.
Did you ever manage to solve it?
Seems like the video starts a few seconds after the alarm is triggered.

You both have a crazy high ImageBufferCount, likely because your systems didn't automatically adjust it during an upgrade to 1.36. That defaults to 3 now. You might realistically set it to 5 if video playback isn't smooth. Setting it so high means your system will be using a lot of ram unnecessarily.
Please look in your logs. I am suspecting that there are complaints about dropping packets from queue and not keeping up.

The logs shows the following details during the alarm:
(above alarm event code is: 1382)

If i change the
ImageBufferCount down to 3, how long will the recordings be before the alarm goes off?
I want the recording to store a few seconds before the alarm goes off, in this case 20
pre event image count with a fps of 10 gives me 2 seconds.
The documentation tells me that
pre event image count should not exceed half the
ring buffer size=Image Buffer Size?
