Video generation is the expensive step. Deciding everything in cheap stills first means you only pay for video you'll keep.
The fastest way to spend a lot on AI video is to go straight from a prompt to a clip, look at it, decide it's wrong, and make another. Each try is a full video generation. Most of the money goes on clips that are thrown away.
Professional productions don't work that way, and an AI production doesn't have to either.
A still picture costs a few cents. A second of video costs several cents, and a scene is usually five to ten seconds. One clip can cost as much as a dozen stills. Lip sync costs more again.
So every decision you can make in a still, before any video exists, is a decision made at a fraction of the price.
A storyboard is the list of shots: what happens, who's in it, where, the framing, how it moves. Writing it first means you know what you're making before anything is generated. In Inkreel a text model drafts it from your world's bible and your song or script, for well under a dollar, and you edit it until it's right.
Make a single still for every shot, with the characters' reference sheets attached so faces stay the same. Then look at all of them together. This is where you catch the wrong framing, the missing prop, the coat in the wrong colour, the scene that doesn't work at all.
Fix those in the still: redo it with a note, mark up just the part that's wrong, or match it to the shot before. Each fix costs cents. When every still is right, approve them.
Now each still becomes a clip. Because the clip starts from a picture you already approved, the first try is usually close. You're not using video generation to discover what the shot should be; you already know.
If one clip still isn't right, redo that one shot. Nothing else is touched.
Even an approved still can give a clip with one thing wrong: the light, a stray figure, the camera moving too fast. Remaking the whole clip is a full video generation again, and the next try may get something else wrong. Clip-fix models take the clip you have and change only what you ask, in words or by marks drawn on a paused frame, for about the price of one short clip. Keep the take you like; fix the one thing.
Once a studio has one finished project, its establishing shots, inserts and sound beds exist. A new project in the same world should take them rather than pay for them again. Inkreel offers them scene by scene, free, and can tell the storyboard writer what already exists so it writes matching shots.
Approving the storyboard and the stills are the two moments where you stop and look. In Manual mode you also accept each clip. In Auto mode you confirm the whole cost once and let it run, still stills-first.
Decide in words, then in stills, and only then in video. The later a mistake is caught, the more it costs.
