Thanks very much, I'll give it a shot. I don't understand why frame rate default is 25fps--a most peculiar rate if that's intended to help with film or video. Film, of course, runs at 24fps, sometimes 30 if intended to transfer to video. Video in the US normally runs at 29.77 drop or non-drop frame. Obviously, there are other frame rate standards in use for web, large format cinema, HD video, and foreign, both lower and higher fps, but 29.77 is the basic US broadcast standard. So, why 25fps for Logic? 25fps is primarily used for TV in the UK and other countries on a 50Hz power standard.
