Turn a brief into a narrated video with the AI assistant

One message can start a whole short film. When you describe a story to the AI assistant, it writes a script, cuts it into shots, draws the opening frame of each shot, and stops with a storyboard for you to review. Rendering starts only after you approve.

Start the run

Set your frame first. Every shot renders in the project's shape, and the shape is frozen when you approve the plan. Open the Aspect ratio tab in the left panel and choose Widescreen (16:9) or Vertical (9:16) before you ask. A custom ratio uses the closer of the two.

Open the assistant with the Agent button and describe the production. Phrases like "tell a story about a lighthouse keeper who finds a message in a bottle" or "turn this into a narrated 20-second short" signal that you want the full pipeline. A plain request such as "make a video of a lighthouse" produces one clip.

A good brief covers the subject, the tone, the rough length and the look. Name the clothing and props that return in several shots, such as a red raincoat or a brass lantern, so shots rendered one at a time still match. Titles, subtitles and extra music come afterwards as separate requests, and exact on-screen wording belongs in a title, because video models garble lettering.

Review the storyboard

A card titled Generate video appears in the chat under your message. Its status moves from Planning to Storyboard ready, and an Activity list narrates each step as it happens. The Plan line shows the shot count and total length, and each Shot tile shows its opening frame with a one-line description.

Planning and redrawing a storyboard frame do not spend credits, so use this stage:

• Hover a tile and click Redraw this frame to replace one frame.
• Click a tile to see its frame large.
• Tell the assistant what to change: "shot 3 should be at night" or "make shot 2 wider".

Approve and render

When the frames look right, click Approve & render, which shows the shot count, or tell the assistant to go. Each shot render spends credits, which is why the run waits for you. The assistant cannot approve a plan in the same turn that created it.

Shots render in the background and land on the timeline as they finish. The card shows a progress bar and a placed count such as 3/6, and a soft music bed sits under the cut. When everything is in, the card reads Video ready.

A shot that cannot render as video holds a still frame and carries a still badge. The card says how many held a still and offers a Retry N shots button for those shots.

Revise by scope

Pick the smallest fix that solves the problem:

• One shot. Hover its tile and click Redo this shot, or ask for it by number with a note such as "more energetic". Only that shot renders again, and the new clip swaps in place.
• A section. Ask to re-cut a span: "split the last shot" or "shots 2 to 3 drag, tighten them". Only that span is replanned, with the same audio, the same look and every other clip kept. Only the new shots render.
• The whole look. Ask to restyle: "make it black-and-white film noir". Every shot renders again, so the assistant confirms first.

Starting a fresh scene to change one part re-bills the whole video, so use the smaller fixes first.

Animate audio you already have

If your project has a voiceover or a song, ask the assistant to animate it. Shots tile over that audio and no new script is written. The assistant listens first and writes a brief from what it hears. Long files mean many shots, so trim silence beforehand.

Write your brief

Set your aspect ratio in DepCut, press ⌘J, and describe a 20-second story. Review the storyboard before you approve.
