Image to video
First frame, last frame: how an AI commercial starts as stills
For the brand manager or agency producer approving an AI commercial, who is shown stills before any motion and wants to know what to look for in them.
The short answer
In image-to-video, the model starts a shot from a still you give it, the first frame, and if you give it a second still, the last frame, it generates the motion between the two. It is the most direct control a studio has over where a shot begins and ends, and it lets a brand approve the cast, the product and the composition on a still before any motion is made. Ruminate X, an AI film studio in Calgary, makes AI commercials for consumer, pharma and pharmacy brands with every frame generated by AI: every shot is boarded with its framing, movement and duration, and you see the shot list before a single frame is generated.
The modes
Four ways to start an AI video shot
| Mode | What you give the model | What you control | Good for |
|---|---|---|---|
| Text to video | A prompt | The idea; the model invents the frame | Exploring ideas, backgrounds, crowds |
| Reference images | A prompt plus pictures of the person or product | Who and what appears; the model frames it | Keeping a face or a product across new scenes |
| First frame | A prompt plus the opening still | The composition, cast, product and light of the first frame | Most commercial shots |
| First and last frame | A prompt plus the opening and closing stills | Where the shot starts and where it lands | Reveals, transitions, landing on a pack shot |
A commercial usually mixes all four. A studio might generate a mood shot of weather from text alone, then build every shot with a face or the product from an approved first frame, so the parts of the ad that carry the brand start from a picture someone signed off.
Most current video models take a first frame, and several also take a last frame. Clips run from a few seconds to about 15, so a 30-second commercial is many shots, each started, checked and cut on its own.
The reason
Why AI commercials start from approved stills
Money. Most takes get thrown away: the director of the Kalshi ad that aired during the 2025 NBA Finals reported 300 to 400 generations to get 15 usable clips (Mashable, June 2025). At the prices model makers published in September 2026, a rejected still costs cents, and a rejected shot costs dollars.
Approval. A frame is quick to approve: the product, the label, the cast, the wardrobe and the light are all visible and still. A legal or MLR reviewer can check a claim on a frame without scrubbing through a clip.
Control. A first frame fixes the composition, the cast, the product and the light before the model adds motion. Anything the first frame leaves open, from the background to the wardrobe, is left to the model.
The checklist
What makes a clean first frame
- Made at the delivery ratio. Make a separate first frame for each ratio you deliver; a 16:9 frame cropped to 9:16 usually cuts the product or a face.
- At or above the output resolution. A 1080p shot needs a first frame of at least 1920 by 1080 pixels.
- Room to move. Leave space on the side the subject moves toward. A push-in needs detail at the center of the frame; a pull-out needs a world around the edges.
- The product right in frame one. The model carries what it sees, so check the label, the logo and the shape against the real product before the still is approved. See product and label accuracy in AI commercials.
- No type in the frame. Supers, prices, claims and logos go on in the edit, from the brand's real files. A headline painted into a first frame is redrawn by the model in every frame after it, where it can warp. Overs' guide to getting text right in AI images makes the same case for stills: render clean, set the words in a second pass.
- Light that matches the next shot. If the sun is at frame left in shot 4, it is at frame left in the first frame of shot 5.
- The moment before the action. One action per shot. The first frame shows the runner about to tie the lace, not halfway through it.
- A last frame close to the first. For interpolation, the end frame should share the place, the light and the lens with the start frame, so the model moves between them instead of cutting.
The prompt
What to write with the frame
The still fixes what the shot looks like. The motion prompt says what happens: the camera move, the action, the timing, what stays still and what the shot sounds like. A vague prompt such as “make it move” leaves all of that to the model.
An example motion prompt, written for this page for a made-up shoe ad:
Slow push-in from a medium shot to a close-up over six seconds. The runner ties the lace on the left shoe, then looks up toward frame right. Leaves move in a light wind. The shoe and its logo stay sharp and do not change. Forest ambience, footsteps on gravel, no music.
Every line of it can be checked against the result, and the line about the shoe names what must not change.
The stills
Where Overs comes in
The first frames of an AI commercial are stills, and often the campaign stills themselves, which is where Overs comes in. It is the sister product from the same founder: an AI tool that makes product and campaign photos that match a brand, without a photo shoot, built on the process 100creatives used to make hundreds of photos a week for hundreds of brands.
Two of its features go straight at the parts of a first frame that break most often, the person and the product. For a product that is worn or held, Overs makes a character sheet first, one model from several angles wearing the exact product, and every later photo with a person uses that same model. Each photo gets only the reference pictures it needs, in order, and if a needed reference does not exist, Overs skips it instead of guessing with the wrong one. You see the shot plan and an estimated cost before anything renders, and you approve, change or reject every photo. For each photo, it can write a motion prompt for Seedance or Veo, so each still comes with a written starting point for the motion. Overs makes no video itself; the motion happens in the video model.
Stills are the cheap end of the job. In 4 campaigns 100creatives made in 2026, a usable photo took about 8 renders, which comes to $0.27 to $1.69 in AI fees per usable photo at published model prices. The free plan makes 40 photos a month, with the AI billed to your own OpenRouter key at a few cents a photo and no markup from Overs. Try Overs free at www.overs.studio and approve your first frames before a single second of video is paid for.

Questions buyers ask
What is first frame last frame in AI video?
It is an image-to-video mode where you give the model two stills: the frame the shot starts on and the frame it ends on. The model generates the motion between them. With only a first frame, the model starts from your still and decides where the shot goes. Model makers call the two-frame version interpolation, or start and end frames.
Why do AI commercials start from stills?
Because a still is quick to remake and quick to approve, and a shot of video is neither: it costs more to generate, and every take has to be watched end to end. At the prices model makers published in September 2026, a still costs cents and an 8-second shot can cost a few dollars, and most takes get thrown away. Approving the cast, the product and the composition on a still before motion keeps rejected takes cheap.
How long can a first and last frame clip be?
Short. Most video models make clips from a few seconds up to about 15, and start and end frames work best over a few seconds. Longer shots are built by extending a clip or by cutting several shots together in the edit, each with its own first frame.
Can I use my campaign photos as first frames?
Often, if the photo is at the aspect ratio and resolution of the video, has no text or logo set into it, and leaves room in the frame for the planned camera move. A 4:5 feed photo cropped to 16:9 usually loses the top of the product or the head of the person, so make a separate first frame for each video ratio. You also need the rights to the photo, and people in it must be cleared for the new use.
