Sometimes I'm working in the edition of my videos and then I notice the start and end area marks are moved. Curiously, end mark is located before the start area. I try to set a new position for the end area but it doesn't move. I cannot play from any position of the time ribbon because it always starts from the beginning.
The only option that I have is to copy all objects and paste them in a new movie. But the chapter markers are not copied and I have to add them again.
Is there any way to reset the position of the start/end marks to a default position or to the beginning of the first element and the end of the last one?
