Wassup in a Minute AI prompt (and when you don't need one)

Use it with three reference photos in an app that takes images:

Horizontal 16:9 handheld phone video on a misty green hillside, a lake and cloudy mountains behind. Three friends in a loose row, person A in the middle, B on the left, C on the right and nearest the camera. C pouts at the lens; all three groove with bent arms, then on the beat slap both hands onto the top of their heads and keep them there, A laughing, C wide-eyed. Hard cut: A chest-up in the centre, rolling finger guns at the camera and lip-syncing, B and C small behind with arms up, grinning. Hard cut: the three side by side bouncing on the spot. Hard cut: wide shot, the three spread out across the slope freestyling.

• The head slap landing off the beat, or not at all.
• Three faces blending or swapping places between shots.
• Clips cut off at 5 or 10 seconds, before the row and the freestyle.
• The hillside turning into a different place in each shot.

The generator already has the hillside, the camera and every move set up. You add the photos; there is nothing to write.
