    I notice that your MIDI timecode is 30fps - so you should set your Cuelist time to 30fps - not25fps

    If you want the cue to run at 00:02:30:10, then you must set the cue time to the same 00:02:30:10

    You should put a blank cue at the end of the list at 24:00:00:00 (or greater than your largest timecode)
    This will ensure that the cuelist never hits the end and stops. - it is possible that this is what is happening to you...
    Since your timecode may be changing depending upon the song, this will help to ensure that the list does not get stopped and remains in 'play' mode.
    Ensure that the 'stop after last cue' option is NOT enabled...

    It may also be worth adding a 'reset black' cue at 00:00:00:00 - so if you reset the timecode during rehearsals, this will reset the layers before the correct cue is triggered.

    During rehearsal, if you reset your timecode back to 00:00:00:00 you may need to click the 'back arrow' (to the left of the stop button)

    See attached screenshot showing a MIDI cuelist as described.
    No matter what the incoming timecode - it always jumps to the correct cue

    Let me know if this helps

    Using playmode 'Sync to SMPTE L'
    If you want your video clip to sync to 00:35:04:08 then you must set the inframe value to:

    @25fps: 52608 (frames)
    or
    @30fps: 63128 (frames)

    this will play the first frame of the movie at the timecode you specified


    Please note - currently inframe and outframe values are 16bit.
    This means that timecode sync can only achieved up to 65536 frames:
    00:43:41:11 @25fps
    00:36:24:16 @30fps

    HOWEVER:
    If you need to sync beyond these values, then you must use another (better/newer) sync method and catalyst version m364
    NOTE - this only works for SMPTE timecode - not MIDI timecode...

    1) Open Library/Files HUD
    Each clip has a TC entry under the Lib and File lines.
    2) Set the timecode of the clip as required (your example = 00:35:04:08)
    3) Set the playmode to 27 'Sync to SMPTE L - autoload timecode offset'
    4) Set the inframe and outframe zero (0)
    (unless you need to adjust the sync either forwards or backwards slightly...)

    you will see the clip playback when the SMPTE timecode reaches the programmed time.

    The attached picture shows the SMPTE timecode at 00:47:19:20 (@25fps)
    The file (lib0 file15) TC has been set to 00:47:10:00
    Layer 1 is playing the file using playmode 27 'Sync to SMPTE L - autoload timecode offset'
    The movie started playing at 00:47:10:00 and the current frame is 246 (ie 9s20f @25fps)


    NOTE
    This method is especially useful for completely timecode shows where video content creators use the Bands' audio tracks to create their compositions. Designers can export their content directly from FCP or AE with the timeline timecode, which should match the Bands' audio playback timecode.

    This makes the whole process of syncing content to timecode much easier and avoids the previous 43min and 36min limits.


    Hope this helps
