All scenes advance manually. Animations are silent, wait for your cue, and hold their final frame. Narrate over the images.
The 50-minute plan includes 7 minutes 20 seconds of animation. The clock begins when you play the first animation, advance, or choose Start clock. Changing tabs pauses media and the clock. Use Resume clock when you return.
For two displays, open the synchronized audience window and move it to the projector. Press F in that window for full screen. Keep this notes window on your laptop.
