When I'm in this crop mode, I can hit play, or just do the advance frame by frame of course, but since I already did that when I made the markers, it seems like just having to duplicate the effort I already went through. I must not be understanding something that makes markers useful, unless there is a way to select and isolate what is between the markers. If there is a way, I haven't discovered it and could use some advice.
Thanks in advance.
