I am currently running Blue Iris 5.3.7.4. I have been searching for a way to playback a recorded clip frame by frame. It used to be possible to advance or reverse frame by frame with each click of the mouse button. I have figured out that I can advance frame by frame by clicking a little to the right or a little to the left of the pause button, but it takes several clicks to advance one frame. I have searched the help manual and this site, but haven't really found much. I feel like I'm missing something obvious. Is there a simple way to advance one frame at a time with one click on the mouse?
