    why, when the time is in SMPTE 00:35:04:08 inFarame shows in 1289? but when I thought there must be 52,608?

    properties file:
    Playback Mode: 25-sync to SMPTE L
    In Frame 7500
    Out Frame 0
    duration of tracks 6260

    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
