Logic Pro X shows me this:

enter image description here

1 second, 15 fr and 56 sub?

How do I convert that into seconds?

    Frames and subframes, google SMPTE timecode. – user48353 Mar 20 '19 at 22:05
  • @replete that's way to complex for me; there are a "random" number (commonly 24, 25, 29.97 or 30) "fr" in each second, and "sub" is about frame-dropping? I just want to know how I can convert that ^^ into literal seconds :c – theonlygusti Mar 20 '19 at 22:12

    It is possible to show milliseconds or samples instead of “bits” (aka subframes) in the time display. That way you don’t have to convert at all. See: support.apple.com/kb/PH13440?locale=en_US&viewlocale=en_US – Todd Wilcox Mar 21 '19 at 3:20

This is an SMPTE timecode. fr is frame number. sub is subframe giving higher granularity. To convert this information to seconds you need to know your framerate. Logic Pro uses a value of 80 subframes per frame, so to convert frame and subframe to seconds use (frame + subframe/80) / framerate. For example, if your framerate is 24, then you have (15 + 56/80) / 24 = 0.654 seconds.
