Working with 60 fps Timecode
Some high definition video formats, such as 720p60, have a video frame rate of 60
(or 59.94) fps. Final Cut Pro can display 60 fps timecode for 60 fps media files, or you
can choose to view the timecode at 30 fps, using the special 60 @ 30 timecode
60 @ 30 is a timecode display option used specifically with 59.94 and 60 fps video footage.
Because 30 fps is a more universally accepted timecode rate than 60 fps, it can be useful
to view your timecode this way. Also, most DVCPRO HD VTRs display this timecode rate
when playing back 60 fps tapes. Each 60 @ 30 timecode number represents a pair of
video frames, with the second frame distinguished by an asterisk (*).
When you are using 60 @ 30 timecode, Final Cut Pro recognizes asterisks when you
type them into timecode fields. Typing + (plus) followed by * (asterisk) in 60 @ 30 mode
is the same as typing +1 in 60 fps timecode.
Note: Mapping 60 frames to 30 numbers per second is not a new concept. VITC
timecode represents each pair of fields (in other words, each frame) with a single
timecode number. Fields 1 and 2 are distinguished by an asterisk placed on field 2.
60 @ 30 timecode works similarly.
