Hello, new user here. Please can anyone explain why the blue time bar, on the playback function, showes vertical black lines. When playing back, a black line is skipped, the time jumps as well. I would have thought the blue time bar would be solid unless punctuated by an event such as vehicle or person detected. I understand red lines are events but black ones, I don't know.
Thanks for any help.
