Timecode?

[Mr_P]

Hi Matt

If you are controlling catalyst via the GrandMA, then I assume that your MA cuelist will be triggered by timecode...

However, you can also sync a clip to timecode:
Catalyst reads SMPTE timecode via the sound line input.
You need to enable 'line in' via system preferences
Then turn on sound in the 'inputs' window on the HUD (next tab along from video inputs)
You should then see timecode being read in the timecode device in the catalyst control window/list (also can be seen in at the bottom of the stats view on the HUD)

To link a clip to timecode you must select the playmode: 'Sync to SMPTE L' (right does not work.... Richard needs to fix this....)
The inframe value then becomes the sync point.
ie if you need to synchronise a clip to start at 10sec, you would set the inframe value to 250frames (assuming 25fps timecode) or 300frames (if 30fps timecode)

The problem occurs when you get to about 43mins... because you run out of 16bit values with which to sync. 65536(16bit)=about 43mins at 25fps

So if using the MA to control catalyst - the MA cue would start at say timecode 0:0:10:0 (10sec) on your desk. The playmode for that cue would be 'Sync to SMPTE L' and the inframe value of your cue would be 250frames (assuming 25fps).
The inframe also allows you to adjust the sync point of the clip if required - just by changing the frame value...

For Catalyst cuelists - this works in a similar way - but the timecode controls the cuelist.

Simon,

We just had a production were we ran into a bit of trouble with smpte. Qlab controlled by a yamaha DM2000 triggered cat. Sync worked perfectly but there was always an audio dip at the start of the trigger. Any idees what this could have been?

In the end we made a multi-channel audio file and did it all from within cat.

Thanks,

Peter
