MTC interpretation
The MIDI standard supports four of the seven commonly used timecode formats: the 30 fps and
29.97 fps (frames per second) formats are not differentiated in the MIDI specification.
Logic Pro X needs to determine the intended format of incoming MTC (MIDI Time Code) and
interprets it as follows:
•
23.976 fps is interpreted as 24 fps.
•
24 fps is interpreted as 24 fps.
•
25 fps is interpreted as 25 fps.
•
29.97 fps is interpreted as 29.97 fps.
•
29.97 fps drop frame is interpreted as 29.97 drop fps.
•
30 fps drop frame is interpreted as 29.97 drop fps.
•
30 fps is interpreted as 29.97 fps.
Note: MIDI Time Code (MTC) is the MIDI equivalent of the audio-based SMPTE (Society of Motion
Picture and Television Engineers) timecode format.
Manually set a frame rate
