Wan 3.0’s 30-Second Video Workflow: Planning Scenes, Motion, and Sound

Thirty seconds sounds like plenty of room for an AI video. That can be the trap. You start with one simple idea, then add a second location, a close-up, a camera orbit, a line of dialogue, and a dramatic ending. The prompt gets longer, but the clip no longer has a clear path from its first frame to its last. A useful way to plan 30 seconds is to treat it as one small scene with a beginning, a change, and an ending. You can decide what each part needs to show before opening a video generator. Start with one visible change Imagine a clip of a desk lamp beside an open sketchbook. The room is dim. A hand switches on the lamp, light spreads across the page, and the camera moves closer to the drawing. That is enough for one scene. The viewer can tell what changed without a caption: the page was hard to see, and now it is illuminated. If the brief also asks the hand to pick up the book, carry it into another room, and show a finished drawing, you may be planning several shots rather than one. Write the intended change in a sentence before writing the prompt: A dark desk becomes a warm, readable workspace when the lamp turns on.

If you cannot say what changes, a longer duration will not give the clip a story. Give each part of the clip a job The timings below are a planning guide, not a promise that a generator will obey exact second marks. Approximate time What the viewer needs to see 0–6 seconds Establish the lamp, sketchbook, and dim room. 6–22 seconds The hand turns on the lamp; light spreads across the page. 22–30 seconds The movement settles, leaving a clear final image.

Notice how little happens. The middle has one main action. The ending has time to register instead of arriving just as the video stops. This is also a useful check for your brief: if every row requires a new place, character, or camera setup, split the idea into separate clips. Choose one dominant motion For this example, the important movement is the hand reaching for the switch and the light changing. A slow camera push can support it. A fast orbit around the desk would compete with it. When planning movement, separate three things:

• Subject action: What moves or changes in the scene?

• Camera movement: How does the viewer’s position change?

• What stays fixed: Which objects, shapes, and parts of the setting should remain recognizable? The third point is easy to forget. If the lamp changes shape halfway through, the clip may look busy even though the requested action is simple. Ask for a steady layout and give the camera one modest job. Here is a compact prompt for the desk scene: A single continuous shot in a quiet studio at dusk. A matte-black desk lamp stands beside an open sketchbook. Begin with the lamp off and the desk in dim natural light. A hand enters from the left and switches the lamp on. Warm light spreads across the page as the camera slowly moves closer. End on a steady view of the lit sketchbook. Keep the lamp shape and room layout consistent. Sound: one switch click and soft room tone; no dialogue or music.

This is an illustrative prompt, not a report of a generated result. Its purpose is to show how the beginning, action, ending, and sound can fit together without competing instructions. Plan the sound as carefully as the picture Sound can clarify a short scene. In the lamp example, a switch click marks the exact moment something changes. Quiet room tone fills the rest without drawing attention away from the page. You do not need dialogue, music, and effects simply because the tool offers audio. If someone speaks, decide what they must say and whether there is enough time for the line to sound natural. If the scene already makes sense without speech, leaving it out may be the cleaner choice. Set up the generation, then inspect the middle Wan 3.0 currently presents options for text-to-video, image-to-video, and reference-to-video, with duration and audio settings; its site describes videos of up to 30 seconds.

For the fictional lamp scene, text-to-video is a reasonable starting point. If a particular lamp design or opening composition matters, an image reference may be more useful. Adding more references is only worthwhile when each has a clear role. Before generating, choose the aspect ratio for where the clip will be viewed and check the selected duration and credit cost. Afterward, do not judge it only by an attractive first and last frame. Watch the middle: does the hand reach the switch naturally, does the lamp remain the same object, and does the sound arrive with the action? If the middle becomes crowded or inconsistent, simplify the next attempt. Remove a camera move or a secondary action. If the idea truly needs several locations or major changes, make separate shots and edit them together. A 30-second option gives a scene more time to develop; it does not mean every 30-second idea belongs in one generation.
