Storyboards and mood boards with AI stills: a pre-production walkthrough
How to build a mood board and a shot-by-shot storyboard with AI stills: lock the look first, render each frame from the same base, then animate the key frame.
A shoot is cheapest to change before anyone turns up. That is what a mood board and a storyboard are for: one shows the feel, the other shows the shots, and together they let a crew, a client or a collaborator say yes or no while a change still costs nothing. Both used to need an illustrator or a stock library. Here is how we build them in the studio in an afternoon, in the order that saves the most re-renders.
Part one: the mood board
Describe the feeling, not the plot
A mood board answers one question: what does this piece look and feel like? So the prompts are about light, colour, texture and time of day, and almost never about what happens. Pick three or four words that describe the world and keep them in every prompt:
Empty seaside cafe at dawn, pale blue light through salt-stained windows, worn wooden tables, a cup of coffee steaming, muted palette of grey, cream and sea green, quiet, film still, 35mmRender six to ten of these on Still Lite, from €0.30 each, changing only the place: the cafe, the pier, a bedroom, a bus stop. Lay them side by side. If they read as one world, the words are right. If one sticks out, it usually means a light or palette word was missing from that prompt, and the lighting guide has the vocabulary to fix it.
Lock the look with a reference
Pick the one board image that feels most right and keep it. From here on it goes into every render as a reference image, so the palette and the grain carry across even when the scene changes. The reference images guide explains what a reference holds steady and what it does not; the short version is that it keeps the look, not the exact objects.
Part two: the storyboard
Write the shot list first
A storyboard frame is a mood board image with a camera and a subject added. Before rendering any, write the list: shot number, shot size (wide, medium, close), what is in frame, and what the camera does. Six to twelve shots cover most short pieces. The list is the brief; the renders only illustrate it.
One base prompt, one line per shot
Keep the mood board words as a fixed base and add one sentence per shot. The base makes every frame match; the sentence makes each one different:
Shot 3, medium shot: a woman in a grey wool coat sits alone at the window table, looking out at the sea, coffee untouched. Same cafe, same dawn light, same muted palette, film still, 35mm- Say the shot size. Wide, medium and close are words the model knows. A frame without one comes back medium.
- One subject per frame. A storyboard frame with three people doing three things is three frames.
- Pick the aspect ratio once. Set it in the composer for the first frame and never change it; a board in mixed shapes reads as a mess. The aspect ratio guide matches shapes to screens.
- Leave the panel numbers to your layout. Ask for the picture only and label the frames in the document where the board lives.
Expect the character to drift
The honest limitation of an AI storyboard is the character. The coat and the hair will match from frame to frame with a reference; the face often will not. For a board that is fine, because a board shows framing and staging, not casting. If a frame needs the same face, start it from the previous frame as its reference and describe the person the same way each time, and accept that some re-rolls will be needed.
Part three: the animatic
A still board becomes an animatic the moment one frame moves. Take the key frame, attach it as the start frame of a video render, and describe a single slow camera move. The photo to video guide covers the motion words; for a board, less is more:
Slow push-in towards the woman at the window, steam rising from the cup, the sea moving gently outside, no camera shakeA clip of 5 seconds on Motion Turbo, from €6.30, is enough to show a client how the opening will breathe. Clips run up to 30 seconds on the longer models, but a board rarely needs them; what it needs is the one shot that sells the mood, moving.
Assembling the board
Download the frames and lay them in a grid in whatever document tool you share with the team, in shot order, each with its line from the shot list underneath. The mood board goes on page one, the storyboard after it, the animatic as a link. Everything in the studio is yours to use for this; the ownership post covers what that means in practice.
What an AI board will not do
- It will not replace the shoot. Boards are for deciding; the real light and the real actor are still the work.
- It will not keep one face perfectly across twelve frames. Treat the character as a placeholder.
- It will not know the location. If you have scouted a place, use a photo of it as the reference and the board will look like it.
See which models take a reference and a start frame, then open the studio, write the shot list, and render the mood board before anything else.
Questions
How many frames does an AI storyboard need?
Six to twelve covers most short pieces. Write the shot list first and render one frame per line; a frame with several actions should be split into several frames.
Can AI keep the same character in every storyboard frame?
Clothes, palette and setting stay consistent with a reference image; the face often drifts. For a board that is acceptable, since it shows framing and staging rather than casting.
What is the difference between a mood board and a storyboard?
A mood board shows the look and feel with no plot: light, colour, texture. A storyboard shows the shots in order, each with a subject and a camera position. Build the mood board first and reuse its words in every storyboard frame.
