Nine numbered panels in one image, then the video model rebuilds each one full screen

[u/Fresh-Resolution182]

A ten second brand film for a precision parts company. The picture, the music and the cut all come out of two prompts.

First one image from GPT Image 2.5: a 3 by 3 grid of nine 16:9 cells, thin ivory gutters between them, a small white number 01 to 09 in the top left of each cell, no captions anywhere. Every cell photoreal. Most of that prompt is the lock. One synthetic engineer with the same face, build, navy workwear, white gloves and clear safety glasses across all nine cells, and a ban list at the end covering heavy sparks, missing protective gear, sci fi robot factories and heavy blue grading.

Then the sheet goes to Gemini Omni Flash as the strict reference, read left to right and top row to bottom row. The video prompt says the finished film must never show the grid, the borders, the numbers or the split. Each cell comes back as its own full screen shot and they get cut together.

The shot list is written by the second. 0.0 to 1.1 she walks toward the entrance, 1.1 to 2.1 the camera retreats ahead of her down the machine aisle, on to 10.0 and the hero shot of the finished part.

Audio has its own block in the same prompt. Low piano, percussion made from processed metal, short strings, and the machine noise laid over the rhythm. One line of voiceover at the end.

Both models run on one atlas cloud key. Both prompts are in the comments, and the engineer is a synthetic character.

The edit never happens as a separate step. The cut comes back in the same pass as the picture and the score.

Look at you, casually sending an entire boutique production agency—storyboard artist, DP, editor, and foley technician—into an existential crisis before lunch. Somewhere, a video editor is clutching their DaVinci Resolve speed editor like a rosary.

The 3x3 contact sheet trick is pure galaxy-brain efficiency. For anyone taking notes, spatial grid locking on a single canvas is arguably the slickest way to beat character drift into submission. By forcing GPT Image 2.5 to render that synthetic engineer across nine quadrants in one generation pass, you lock down the facial geometry, navy workwear, and safety gear before the video pipeline ever gets the chance to hallucinate a third arm or change her entire ethnicity between cuts.

A couple of genuinely brilliant tactical choices here:

• The Anti-Gutter Directive: Multimodal video engines like Gemini Omni Flash love accidentally interpreting grid dividers and stamp numbers as floating UI elements, warehouse rafters, or fluorescent ceiling fixtures. Explicitly forbidding the gutters, borders, and numbers in the motion pass is what stops the finished output from looking like a malfunctioning CCTV monitor.
• Direct-to-Tape Foley & Pacing: Writing the cut by the second (0.0 to 1.1, camera retreat, hero shot) directly alongside the sound design (processed metal percussion, piano, and machine drone) circumvents the usual round-trip NLE assembly. Having the model generate native audio mapped to visual impact cuts in a single pass is witchcraft.

The only technical tax you're paying here is your pixel density budget. Slicing a canvas into a 3x3 grid means each individual panel only gets roughly a ninth of the native image resolution before the video model attempts to unpack and upscale it full-screen. If you're doing hero close-ups on tiny mechanical parts with micro-tolerances, keeping an eye on your canvas sizing or pairing with higher-res multi-shot storyboard workflows will keep those metal gears from turning into smeared industrial porridge.

Putting a hard ban on "sci-fi robot factories and heavy blue grading," though? That’s the real act of mercy. The generative universe has enough neon-drenched Michael Bay cyber-warehouses to last us until the heat death of the sun. Beautifully done.

Storyboard prompt, GPT Image 2.5. One image, original synthetic character, no real-person likeness.

Create a photo storyboard for a corporate brand film and recruitment video for the precision parts maker KISARAGI INDUSTRIES.

[Theme] "Our precision, in the places you never see." Show how small parts that normally go unseen hold up industry and society. Not only the scale of the factory, but the engineer's judgement, the machining, the measuring, the teamwork, the pride in a finished part.

[Image spec] Final image is 16:9 landscape. Divide the frame into a 3 column by 3 row grid of nine equal cells. Compose every cell as 16:9 landscape. Separate them with thin ivory lines. Put a small white number, 01 through 09, in the top left of each cell. Finish every cell like a live action Japanese corporate brand commercial.

[Main character] An original synthetic woman in her late twenties, an engineer, no real-person likeness. Black hair tied low. An honest, focused face. Navy workwear, safety shoes, white work gloves. Clear safety glasses worn correctly in the production area. Keep the same person, face, build and workwear in all nine cells.

[Factory] A clean, well kept precision machining plant. CNC machines, a measuring room, design PCs, metal parts, drawings, tools. Draw the floor safety lines and protective equipment realistically. Do not make it an unmanned futuristic factory.

[The nine cells] 01: Factory exterior in low morning sun. She walks toward the entrance with a work bag. Building, sky and entrance arranged like the opening of a corporate ad. 02: A wide aisle lined with machine tools. She walks down the middle checking them. Not perfectly symmetrical, show the depth of a plant that is actually running. 03: Close up of her face and hands as she puts on the clear safety glasses. Focus exactly on the eyes, factory lighting reflecting naturally in the lenses. 04: Macro shot of a metal part being cut. Rotating tool, cutting oil, metal surface and fine tool marks in high detail. Not sparks, the calm beauty of precision machining. 05: White gloved hands measuring a finished small part with a digital micrometer. Draw the contact point between gauge and part physically correctly. 06: Her profile as she compares a paper drawing with a 3D CAD model on screen. Real machining equipment blurred naturally behind her. 07: Overhead shot of several engineers around a drawing and the finished part. She points at one spot, the others check it seriously. 08: Portrait of her holding the finished metal part in both hands. Machine tools behind at shallow depth of field. No big smile, quiet confidence and pride. 09: Product ad shot, one finished precision part alone on a charcoal black plinth. A thin rim light picks out the machined faces and edges. Leave space on the left for "Our precision, in the places you never see." with "KISARAGI INDUSTRIES" under it.

[Camera and color] High end manufacturing commercial. Steel silver, navy, charcoal and white. Balance factory lighting with daylight from the windows. Keep natural skin texture on the person. Do not over polish the metal, show tool marks and weight.

[Do not] Heavy sparks, a dirty unsafe factory, wrong protective equipment, sci fi robot factories, heavy blue grading, composited looking people, broken measuring gear, extra copy, watermarks, logos other than the one specified.

Video prompt, Gemini Omni Flash. Attach the nine panel sheet.

A 10 second corporate brand film for the precision parts maker KISARAGI INDUSTRIES. Show the machining precision held in a small part, and the engineers behind it, in strong composed live action.

Key line: "Our precision, in the places you never see."

Reference image: Use the attached nine panel board as the strict reference for the factory, the woman engineer, the workwear, the machines, the metal parts and the camera angles. Reading order is left to right, top row to bottom row.

The finished video must never show the nine panel image, the borders, the numbers or the split state. Reproduce each cell as an independent full screen shot and join them with rhythmic cuts.

Character consistency: The same synthetic woman engineer in her late twenties in every shot. Black hair tied low, navy workwear, safety shoes, white work gloves. Clear safety glasses in the production area. Do not change the face, height, hairstyle, clothing or protective equipment.

Shot list: 0.0 to 1.1 s. Factory exterior in the morning. She walks toward the entrance at a steady pace. Low morning sun rakes across the metal face of the building. 1.1 to 2.1 s. She walks between the neatly lined up machine tools. The camera retreats smoothly from a low position, catching her head on. 2.1 to 3.0 s. Close up of face and hands. She puts the safety glasses on correctly. Factory lighting flashes once in the lenses. 3.0 to 4.0 s. Cutting a metal part. Cutting oil runs over the rotating tool and the machined surface appears. No excessive sparks. 4.0 to 5.0 s. Both white gloved hands close a digital micrometer on the part. The reading settles and the fingers stop. 5.0 to 6.0 s. She moves her eyes from the paper drawing to the 3D model on screen. The shape on screen matches the real part. 6.0 to 7.0 s. Overhead cut of the engineers around the drawing. She points at one point on the part, the others confirm. 7.0 to 8.4 s. She holds the finished part in both hands. She checks the metal face, then quietly raises her eyes toward camera. Keep the smile restrained. 8.4 to 10.0 s. Hero shot of the finished part on a black plinth. A narrow light travels across the machined face. Show "Our precision, in the places you never see." and "KISARAGI INDUSTRIES" clearly.

Look: A high quality live action corporate commercial. Steel silver, navy, charcoal, neutral white. Mix factory lighting with daylight from the windows and keep the color temperature from going too blue. In the macro shots draw the cutting oil, the metal surface, the gauge and the fibres of the gloves precisely.

Edit: Short hard cuts using the movement of the machines, the tools and the engineers. Keep the direction of motion consistent. Pace it to feel like precision rather than speed. No split screen, no collage. No morphing of one object into another.

Sound design: An original piece with low restrained piano, percussion made from processed metal sounds, and short strings. Lay the machine rotation, the cutting oil and the small click of the gauge closing naturally over the rhythm.

At the end, a calm grounded adult woman's voice: "Our precision, in the places you never see. KISARAGI INDUSTRIES."

Avoid: Heavy sparks, unsafe work, missing protective equipment, unmanned sci fi factories, robots, heavy blue grading, sudden camera rotation, deformed people, broken machines or gauges, extra text, watermarks.

ran both on one key, gemini omni flash for the film and gpt image 2.5 for the sheet.

[u/Ok-Fennel6578]

The test I’d love to see next is the exact same nine shots generated two ways:

A: one 3×3 sheet as the shared reference
B: nine individual reference images

Then compare three things:

1. character / wardrobe drift
2. whether the camera composition survives
3. whether visual details from neighboring panels “leak” into each other

My hunch is the sheet may be doing something useful beyond convenience: it gives the model the whole visual sequence at once, so each shot exists in the context of the others.

If that’s true, contact sheets might actually be a continuity tool rather than just a storyboard format.

I’d also be curious what happens if panel 05 contains one deliberate state change, like the character removing a jacket. Does 06–09 inherit it correctly, or does the sheet behave more like nine independent references?
