I dragged mp4 video file to the bottom and used the Split At Playhead I marked start and end part and clicked the copy button but then when I’m trying to click the + button in the play list window the button is disabled. can’t click it.
what am i doing wrong?
in this screenshot i marked with yellow circle the part i marked start/end then clicked the copy button marked with green circle at the end I’m trying to click + button of the play list marked with red circle. but I can’t click it it’s like the button is disabled.
