what does it mean when the track header is red or green, and how do you switch it?
Green: Track is active (important for 3-point editing)
Grey: Track is inactive
Red: Track is locked
You toggle between active and inactive by clicking on the track indicator.
See this section in the Kdenlive documentation
I have already looked at the description in the manual, but it does not describe how to change the red back to green, as in not locked.
How do you do that?
Click on the lock icon
Ah, yes, that works now. I thought I’d already tried that umpteen times. At least after a restart, the lock now turns red or green.
No, I mean this
Not quite: The lock just locks or unlocks, the track header color changes to red or back to green or grey
Thank you, it was very easy.
It would make sense for the lock to turn red when it is closed.
