Hello Dave
the video options are greyed out when video recording is active as you can't change parameters while recording.
To verify, see the video save folder or the message window.
The state of the 'Restart with new video file' checkbox is saved, but when it's redisplayed it's not initialized correctly.
A corrected version is available in
Issue #375.
In order to get manageable chunks of video you have two options:
- Restart a video file after x minutes in Video Save / Limits
- Start new video after motion detection in Video Save / Control
You can't choose both - it's either or.
When recording on motion detection, you can choose how many seconds to record pre motion and post motion in Video Save / Options.
If recording
after detection overlaps with
pre motion recording of the next motion detected,
'Start a new video after motion detection' won't split the video file,
so if you have motion very often 'Restart a video file after x minutes' may be the better option.
If you have further questions don't hesitate to ask them here.
Maybe I should create a tutorial to explain the different video recording options....
