I'm all to familiar with the continuously film rolling to where I might turn the film on in AvA and then go to the MPA or a special event then end up in the MA and after 4 to 6 hours playing, I realize that I never stopped the film......
It can be a real pita sometimes with some very huge file size and very long films to scan through, especially if their is something you are trying to find to review.....
As for flying/filming scenarios, I use the method of example: Anzio frame 1 film 1, Anzio frame 1 film 2, etc....with each film being the start of a 2nd, 3rd, 4th mission/flight
However, having severe memory loss / dementia is a pita all in itself, heh......
