Using Timecode Sync Playmodes
Timecode Sync does not control any properties of a layer except the playback position and rate. All other functions
must be programmed separately. If a movie is set to one of the three Timecode Sync playmodes, it will sit, paused on
the in-frame until the appropriate time is reached. Thereafter, the movie will play based on the selected Timecode
Sync playmode's characteristics until it reaches the out-frame, upon which it stops on that frame. It will not loop or
fade out.
There are three Timecode Sync playmodes, each of which has its own benefits:
+ 130 - 134 TC Sync -> strict lock to timecode; movie waits for appropriate timecode to initiate playback, and if
timecode stops or goes away, the movie playback stops.
+ 135 - TC Sync then Freewheel -> movie waits for appropriate timecode to initiate playback, but then ignores
timecode for the remainder of that movie’s playback
+ 136 - TC Jam Sync -> movie waits for appropriate timecode to initiate playback, if timecode stops or goes away,
the movie freewheels. However
, if timecode returns, then the movie will resync to the incoming timecode.
If the in-point of the movie is modified, playback will start from that point when the correct time is reached. The
Timecode Offset channel on each layer allows modification of a file's start time by approximately 4 seconds without
having to rename the file and rescan the content. The offset value options are:
+ 0 > 126 - Positive offset (movie plays later) -> 1 point = 1 frame
+ 127 - Default, no offset
+ 128 > 255 - Negative offset (movie plays sooner) -> 1 point = 1 frame
 For a complete channel map, refer to "Play Mode" on page 158.
Inputting SMPTE Timecode (LTC)
SMPTE timecode input can be achieved either directly through the audio line-in port on the Mac computer or via the
SMPTE Input connector on the Auxiliary Input panel. Both balanced and unbalanced SMPTE signals are accepted, as
are both 30fps non-drop-frame and 30fps drop-frame formats.
