A frame splitting at a lit seam, with an empty pane and a plus where the viewer’s video goes.
The duet ask, shown as the layout it produces instead of named in a caption. The empty pane is the instruction — it is the shape of the thing the viewer is about to make, which no amount of copy explains as quickly. Keep the caption to what you want them to add, since the geometry has already said how.
The title is DUET and THIS on two lines, and the caption says what to add: make your version. Keep it short, since the geometry has already said how. The seam colour is the lit line the frame splits at.
Duet This is built at 640 × 360, a 16:9 landscape frame, the shape of a YouTube video, a stream layout and most editing timelines, and runs 3 seconds at 30 frames per second. It arrives in 0.4 seconds, holds for 1.7 and clears in 0.9, so cue it a beat before the moment it labels. Export it as an MP4 for a timeline or a feed, a GIF where video will not embed, or a MOV with an alpha channel to lay it over footage with nothing behind it. Renders go up to 4K, and the free plan exports at 720p with a watermark.
Because it is the shape of the thing the viewer is about to make, and no copy explains that as quickly. The plus in the pane is the invitation.
A stitch is sequential rather than side by side, so the split reads slightly off. Change the title to STITCH THIS and it still works as a prompt, if not a diagram.
