You have a small idea: a paper napkin on an outdoor café table catches a breeze and settles beside a cup. It sounds simple enough to fit in one sentence. For a 15-second video, though, you still need to decide what happens first, what changes, and where the moment ends.
A short prompt could be:
Check that workflow's duration options before generating. If it offers exactly 15 seconds, select that length. If it does not, use a supported duration and finish the timing in an editor—trim a longer render or join shorter, visually consistent segments. The latter will no longer be one continuous shot.
Choose a vertical frame only if that option is available and the video is meant for a vertical feed. If the workflow offers sound, keep it subtle; otherwise, add ambience during editing.
Watch the beginning, middle, and end before sharing. Does the napkin lift and settle, or jump across the table? Does the cup keep its shape? Does the light suddenly change? If something fails, change one instruction at a time. The finished video should be 15 seconds because you checked and edited it to that length, not because the prompt said "15 seconds."
Plan the movement before writing the prompt
Keep this as one scene, not three unrelated ideas:- 0–4 seconds: The napkin and a plain ceramic cup sit on a quiet table.
- 4–10 seconds: A light breeze lifts one corner of the napkin and moves it a short distance.
- 10–15 seconds: The napkin settles beside the cup. The camera holds for a moment.
Give the image and prompt separate jobs
If you have a photo of a table that you have the right to use, it can establish the cup, light, and camera angle. If not, describe the starting scene in text. Keep logos, faces, and readable signs out of the frame unless you have permission to use them.A short prompt could be:
The cup anchors the scene; the napkin does the moving. Adding a circling camera, a change in weather, and a passer-by would make the result harder to assess.One continuous shot of an outdoor café table in soft afternoon light. A white paper napkin lies beside a plain ceramic cup. A gentle breeze lifts one corner, slides the napkin a few centimeters, then lets it settle beside the cup. Keep the cup, table, lighting, and camera angle consistent. No cuts or new objects.
Set up the output, then check it
In Vidu Q3, use the input available in your chosen workflow: a suitable starting image or a text prompt.Check that workflow's duration options before generating. If it offers exactly 15 seconds, select that length. If it does not, use a supported duration and finish the timing in an editor—trim a longer render or join shorter, visually consistent segments.
