Our first renovation animation had the right ending and the wrong route. The oak floor rolled out like carpet. A white duvet-like shape emerged from a navy sofa. We had adapted a sequence from a bedroom without removing its bedroom actions.
The fix was to name the materials and objects in this living room, then give each its own movement. Here is the revised clip.
Open the Living Room Renovation prompt for the shorter reusable video direction and matching endpoint downloads. The full prompt from the local test is below.
Original Image Gen endpoints and an experimental local MiniMax H3 video, made outside Studio. The clip is about ten seconds. The 1080p presentation is an upscale of a 1024 × 576 generation. Unmute for music. This is an imagined renovation, not a completed project or construction record.
Start with a matched room, not two unrelated pictures
We chose a comfortable American suburban living room: a standard flat ceiling, two double-hung windows, a wide doorway, white built-in shelving, oak flooring, a navy sofa and a tan armchair. The goal was an attainable family room, rather than a palace interior.
The completed image was made first with Image Gen. We then edited that image into an unfinished state. This gives the video a common camera and room shell to work from.
The unfinished edit removed the furniture, cabinetry and installed lights. Painted surfaces became drywall with taped seams; finished flooring became an exposed wood subfloor.
For your own room, start with a photograph or render you have permission to use. Keep the completed view as the master. An endpoint-editing brief can look like this:
Edit this completed living-room image into its matching unfinished
before-renovation frame. Keep the exact camera, room corners,
ceiling height, doorway, window openings and outdoor view.
Remove the furniture, rug, decor, built-in cabinetry and installed
light fixtures. Replace painted surfaces with unfinished drywall
and taped joints. Replace the finished floor with the exposed
subfloor appropriate to this building. Keep the window units in
place. Same dimensions and composition. No workers or debris.
That is a reusable editing brief, not the full prompt used to generate our original endpoints. Adapt the unfinished materials to the actual building. An American wood-frame house does not need the concrete shell seen in a different reference.
Compare both endpoints before making the video. Check the window divisions, doorway edges, wall corners and floor perspective. Our edit also made the visible hallway unfinished, so its finishing becomes another change in the clip. These invented surfaces do not reveal a real property's construction history.
Give hard materials and soft furnishings different actions
“Renovate this room” describes the destination. It leaves the model to invent the journey. A useful brief identifies what appears, where it belongs and what kind of movement suits its material.
| Part of this room | First attempt | Revised instruction |
|---|---|---|
| Oak floor | A “spreading wave” curled the floor like a sheet | Individual rigid boards fit flat in adjacent rows |
| White built-in | Generic rising and unfolding | Solid base cabinets, upright panels and shelves assemble in their final positions |
| Area rug | Bundled into a general fabric stage | A separate rug appears on the completed floor before the seating |
| Navy sofa | Generic bedding language produced a duvet-like shape | A complete sofa keeps its frame and fitted cushions; nothing emerges from it |
| Decorative pillows | Included with bedding and curtains | Small pillows appear directly against the backrest |
The distinction is especially useful when moving between room types. A bathroom needs surfaces, sanitary fixtures and fittings. A kitchen needs cabinets, worktops and appliances. A living room needs its actual seating and storage. Leave absent objects out of the brief.
Our revised flooring reads as separate wooden boards. The sofa no longer produces the large white fabric shape seen in the first attempt. Those are observations from this example, not a measured success rate across rooms.
The exact prompt for the revised local video
This is the complete replacement prompt sent to our local H3 workflow. We did not append it to the old bedroom-derived instruction. The time ranges describe the intended order; the output does not follow every time boundary exactly.
One photorealistic, ten-second, locked-camera renovation assembly of this specific American living room, from the supplied unfinished first image to the supplied furnished last image. Keep the camera, lens, wall corners, left doorway, two right-wall windows and backyard view perfectly fixed. Use only objects visible in the last image. Complete one stage before the next; each completed object stays still.
0-2 seconds: The existing drywall becomes smooth warm off-white painted walls and ceiling. White baseboards and casings fit along the existing edges. The room remains empty. All changes stay directly on the existing surfaces.
2-4 seconds: Install the light oak HARDWOOD PLANK floor. Individual straight, rigid wooden boards appear in adjacent rows at subfloor level, starting near the rear wall and progressing toward the camera. Every board has the final image's grain direction, width and staggered joints. Each row clicks flat into place with a tiny horizontal translation. Boards remain flat, solid and attached to the floor throughout. The completed floor is a single stationary level plane: absolutely no raised leading edge, curling, rolling, bending, rippling or lifting. There is no rug yet.
4-5.5 seconds: Assemble the white built-in at the rear-left wall. Solid rectangular base-cabinet sections occupy their final positions, then the upright side panels and horizontal shelves fit into their final slots. Panels remain straight and rigid. Stop the cabinet motion when assembled.
5.5-8.5 seconds: First reveal the cream rectangular area rug ALREADY FLAT on top of the finished oak floor, confined to its final footprint. Keep its entire surface and all four edges flush to the floor; it stays there. Then place the complete navy sofa at the rear-right wall, the tan armchair at the front-left and the solid walnut coffee table between them. Each furniture item appears at full finished shape directly in its own final position and makes one small controlled downward settling motion. The sofa keeps its normal upright back, rigid frame, arms and fitted navy seat cushions at all times; cushions retain their size. Its small decorative pillows appear directly against the backrest and remain attached in their final positions. No object, fabric or material emerges from the sofa. The rug remains BELOW the furniture throughout, never in front of or above the sofa. No bedding, sheets, duvets, blankets, inflated fabric, flying cloth or curtains. Do not stretch, inflate, melt or transform furniture into another object.
8.5-9 seconds: Small books, plants, pottery and the wall artwork appear directly at their final shelf/table/wall positions. The floor lamp, ceiling fixture and recessed lights reach the warm brightness of the last image.
9-10 seconds: Hold the exact completed last-image composition, every object stationary. Maintain stable geometry, straight lines and natural daylight for the entire shot. No people, tools, debris, liquid, cuts, camera movement, text or logos. This is an object-by-object living-room assembly; no whole-room crossfade.
Replace the room inventory before reusing this. Oak boards, a navy sofa and white shelving belong to our endpoint. Your clip should name the objects and materials in yours. Keep the order readable, and give the finished room time to settle.
Using Renovation sequence in the video tools
In Studio's video tools, choose Before & after, add aligned starting and ending photos, then select Renovation sequence. The preset supplies an order of operations. The Room-specific direction field is where you tailor the materials and furniture actions to your own images.
Customize that direction before generating. The living-room example is a starting point, not an automatic analysis of your room. Change the floor material, built-ins, furniture and textiles to match the ending photo. A bedroom prompt can introduce unwanted fabric into a living room.
The tool's revised base instruction separates rigid flooring from rugs and removes the generic bedding action. Use living-room example fills the direction box only when you click it; it does not generate a video. Review and adapt the text, then check the model, length, size and credit quote before selecting Generate. See plans and eligibility.
The full local prompt above is longer than Studio's direction box. Studio adds its own base instructions, so use the shorter in-tool example there. The local clip is not evidence that the hosted Studio model will produce an identical result. Video access depends on the current account and service availability; this article does not enable it.
What we actually tested
We made two local videos with the same endpoint images, seed and sampling settings. The second run changed the text prompt. Both used ComfyUI and installed MiniMax H3 weights, rather than the hosted Studio generation service.
| Setting | Both attempts |
|---|---|
| Local model | MiniMax H3 FL2VA, pruned INT8 |
| Acceleration | H3 FL2V turbo eight-step LoRA |
| Conditioning | First and last image |
| Generated dimensions | 1024 × 576 |
| Playback | 243 frames at 24 fps, 10.125 seconds |
| Seed | 2026102601 |
| Sampler / schedule | res_multistep / simple |
| Presentation copy | 1920 × 1080 upscale with light sharpening and music |
The original images are 1672 × 941 and were resized for the local video input. The music is an excerpt of Alex Morgan's “Corporate Business Background,” previously selected for our films. These local settings are a reproducibility record, not a Studio service speed estimate.
The remaining artifact is part of the result
Watch the middle of the revised clip. The rug briefly floats and bends before landing, despite the instruction to keep it flat. Some furniture fades or changes scale as it appears, instead of arriving as a fully formed object. The floor boards also resolve into the final floor texture rather than showing a literal installation.
The room shell and openings stay broadly consistent in the inspected frames, but that does not establish exact geometry or construction accuracy. The supplied ending image helps the model land on an attractive final view. Judge the path there as carefully as the landing.
This effect suits a clearly labeled concept film or a design presentation. It should not be used as evidence of completed work, an installation method or a construction schedule. If an edit is used in property marketing, label proposed changes and review it against the real property.
The sequence was inspired by 四喜AI's renovation video on Rednote. Prompt inspiration only. We did not recover the creator's original prompt. All endpoint images, prompts and video shown here are our own; none of the creator's footage or music is reused.
For the exterior version of this problem, see our building growth animation workflow. The same lesson applies: describe the intermediate states that fit the subject, then inspect what the model actually does.
