I have found the key to view a video file frame by frame (very useful for choosing a particular frame as a picture) , but the general info of the program also mentions the possibility of going frame by frame BACKWARDS... this can be very useful too, in case you just missed an interesting frame and wish to go back to it ...
Unfortunately I haven't been been able to find a way to do this, I have been able only to jump backwards by 50 or 60 frames or so... Is there really a way to go backwards ONE frame by ONE frame, and what is the associated key ?
Thanks in advance !
