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

