AI video: build a short sequence from three clear shots

Plan the edit before generating the footage

A video can contain attractive images and still fail to communicate a simple action. Before opening a generator, decide what the viewer should understand at the end. For our original practice project, the message is: a paper boat leaves a desk and begins a journey. The exercise uses three short shots rather than a complete story requested in one prompt.

Runway's image-to-video guide ↗ recommends concentrating text prompts on motion. Adobe's Firefly documentation ↗ describes first and last frame guidance and notes that adding frames disables some controls. Available settings depend on the selected tool and workflow; check them before planning an experiment.

Make a tiny storyboard

Write three cards: the boat rests beside a window, it slides toward the edge of the desk, and it floats across a shallow tray of water. Give each card one purpose and an intended duration. Four seconds per shot is a suggested design for this exercise, not a universal generation limit. If a tool outputs a longer clip, trim it during editing.

Keep a small continuity note: a blue boat, warm afternoon light, and a window on the left. Prepare an approved starting image for each shot, using your own assets or materials you have permission to use. Inspect the still images first. A successful motion test cannot repair a character or object you already dislike in the starting frame.

Separate movement from visual design

For the second shot, our example direction is: the camera stays still while the boat slowly slides toward the desk edge; the curtain moves lightly. This instruction is an original exercise example, not a tested recipe. Start with one main action. If the result changes the boat's shape, simplify the action before adding another camera move.

Generate a small number of alternatives. Compare them with the storyboard, rather than choosing the most spectacular clip. Record the prompt, reference image, selected settings and reason for rejecting a take. Change one important variable at a time so the next result teaches you something.

Assemble meaning in the editor

Place the three accepted takes in sequence. Trim each to the useful movement and compare neighboring shots for shape, lighting and direction. Add a simple cut before experimenting with transitions. Use sound you created or licensed, then decide whether the story needs a caption. Watch once without sound to check whether the action remains understandable.

A practical acceptance test

Export one short draft. Ask another person to describe what happened without seeing the storyboard. If they cannot identify the departure and journey, revise the shot order or the middle action. Save the project and the rejected takes. The aim is a repeatable editing decision, not a promise that a particular model will produce a flawless film or earn money.
