This tutorial workspace demonstrates the various blend modes available in QLab.
The workspace uses two Video cues, cue L1 which plays a video of an ocean shore on layer 1, and cue L2 which plays a video of a city skyline on layer 2. A set of Network cues lets you change the blend mode used by cue L2. A Text cue, cue T, displays the blend mode currently in use. Another Network cue, set to run for 24 hours, uses an OSC query to get the blend mode currently in use, and set the text of cue T.
