TIME CODE OPTION FOR SYNCING VIDEO AND MUSIC

I have been pretty active with this app, but for the life of me, it would be so much easier if you had a timecode option that would allow you to match music and video perfectly and have in and out points. Another thing that’s on my mind is that the set points are not available in widescreen mode. So how can I match up my in point simultaneously if they’re not available in that mode…suggestions? what am I doing wrong
