Normalize / Sync Between VDMX, QLab and DMXIS

#1

Thanks to the great tutorials I’ve figured out how to normalize Page and Page 1, the two (different) videos I’m projecting to different screens. QLab triggers the pre-programmed (one note) MIDI triggers. But QLab triggers two children simultaneously - the one for VDMX and one for DMXIS, which a full pre-programmed MIDI light show to accompany the videos. Obviously they need to sync, so I’m slowing down the DMXIS triggers via QLab’s pre-wait setting. The trouble is that the latency between the DMXIS and VDMX triggers varies a lot.

My awkward solution is to normalize the two videos in VDMX, then use Quicktime to record the screen while playing everything. Then I use Final Cut to measure the variance between VDMX and DMXIS. Next I add the prewait number in QLab (guessing). So it takes forever to syncronize everything each time I restart my computer. Is there a better way?

My only suggestions is to make sure you are preloading media files in VDMX, this can speed up triggering.

Thank you David! I will do that. I’m also going to look into converting my video formats.

Thank you for all you do. Your tutorials are excellent.
