Turning architecture competition boards into motion
A practice's best work is usually unbuilt and flat. A keyframe-sequence method for moving competition boards, plus the NDA and credit rules on publishing.
Most practices have the same imbalance in their portfolio. The built work is photographed properly and moves — somebody shot a walkthrough, a drone did a pass over the roof. The unbuilt work, frequently the more interesting and always the more ambitious, exists as a set of A1 boards: a site plan, two sections, four diagrams, one hero perspective, and a photograph of a chipboard model taken under fluorescent light. A board reads in a jury room and dies in a feed, and commissioning archviz motion for a competition entry that did not win is a spend nobody signs off.
Still-to-motion keyframing is the middle path. You already own the frames; what you lack is the movement between them. A model conditioned on a start image and an end image will generate the interpolation, and if you sequence those pairs carefully you get a portfolio-length cut out of material already in the project folder.
Two things to be clear about first. This is not a substitute for archviz — it will not produce a physically accurate, materially correct walkthrough for a client deliverable, and you should not present it as one. And what you may publish is decided by the competition brief and the client agreement, not by what looks good.
Inventory the frames you already own
Lay out every image asset for the project and sort it by whether it can serve as a keyframe. A keyframe is an image with a legible camera position — something a viewer reads as a view, not a drawing.
| Asset | Keyframe? | Best use |
|---|---|---|
| Hero perspective render | Yes | Start or end of the main move |
| Secondary perspectives, interiors | Yes | Middle keyframes in a chain |
| Physical model photography | Yes, often the best | Massing and context sequences |
| Axonometric or exploded diagram | Animate, do not interpolate | Programme and system reveals |
| Plans, sections, elevations | No | Overlay layers and title beats |
| Site photograph | Yes | Opening context, before the design appears |
The count that matters is how many true perspectives you have. Two is workable, four is comfortable, one means your first job is producing a second — and the right way is an instructed edit off the existing render rather than a fresh text-to-image generation, because the edit inherits the geometry and the generation invents its own. Qwen Image Edit 2511 works this way. Whichever model you use, check its behaviour on straight lines and vanishing points first; which image models hold architectural perspective is the shortcut past a lot of testing.
The keyframe sequence method
The unit of work is a segment: two images and the move between them. Build the film out of segments rather than one continuous shot, because a long single generation drifts and a chain of short ones does not.
- Order the frames as a narrative, not a tour. Context, approach, arrival, the move that makes the scheme work, then a diagram explaining it. Five to seven segments carries that story.
- Pair adjacent frames into segments. Segment one runs from the site photograph to the wide perspective; segment two from the wide perspective to the courtyard view, and so on. Every frame in the middle of the chain anchors two segments, which is what keeps the whole thing continuous.
- Generate each segment with first-last-frame conditioning. You supply both ends; the model produces the camera move between them. Veo first-last-frame is built for this, and the failure modes are covered in first-last-frame transitions and loops.
- Chain by handing off frames. Take the actual last frame of the rendered segment — not the source image you fed in — as the first frame of the next. The rendered frame carries whatever the model did to lighting and material, and starting from the source produces a visible snap. Keyframe chaining for longer scenes covers the handling.
- Animate the diagrams separately. An exploded axonometric wants a build-on reveal, not a camera move. Treat those as stills with timed layers in the editor — the linework stays crisp and the labels stay typed rather than rendered.
- Assemble at the pace the work deserves. Architecture reads slowly: four to six seconds per segment, hard cuts, no whip transitions. Six segments is roughly half a minute of motion, and the animated diagrams, title cards and credits take the finished cut to about a minute. The default frame rate is 25 fps, the right cadence for this material.
Prompting a move that respects the geometry
The failure mode is the model editorialising: it adds a storey, curves a straight parapet, invents glazing mullions, populates the plaza with people casting shadows in three directions. On a competition scheme every one of those misrepresents the design.
Write the prompt as pure camera language and forbid change explicitly:
Slow forward dolly at constant height from the first frame to the last. The building geometry, materials, glazing pattern and roofline remain completely unchanged throughout. Overcast daylight, consistent from start to finish. No people, no vehicles, no vegetation growth. No camera roll.
For a massing or model-photography segment, an orbit reads better than a dolly:
Slow orbit to the right around the physical model, constant elevation, ending at the second frame's viewpoint. Studio lighting stays fixed. The model itself does not change. Shallow background, no added context.
Two habits keep this reliable. Name the move using standard camera control vocabulary — dolly, orbit, crane, push, pan — rather than describing an emotional quality, because that vocabulary is what these models respond to. And review every segment for geometry drift before chaining, since a drifted frame propagates into everything after it.
What a practice is allowed to publish
This decides whether the film ever leaves the office, and it is worth resolving before production rather than after.
The competition brief governs the competition entry. Open competitions routinely impose anonymity during judging and publication embargoes extending past the announcement, and some briefs assign exhibition or publication rights to the organiser. Read the clause and diary the date the embargo lifts — an unsuccessful entry often becomes publishable on a known date, which makes it a scheduled asset rather than a dead file.
The client agreement governs commissioned unbuilt work. Confidentiality provisions on schemes that did not proceed are common and frequently broader than people remember. Where a project was abandoned, the client may have specific reasons for not wanting it visible. Ask in writing, and take a no as final.
Credit accurately, every time. Professional conduct standards in most jurisdictions require truthful attribution of work: name the practice that held the commission, name your own role honestly, and do not present work performed at a previous employer as your own. On a title card that means "Design architect: [firm]. [Your name], project architect, while at [firm]." Less snappy, and the only version that survives scrutiny.
Credit the collaborators. Structural, services, landscape, and — if a visualisation studio produced the render you are animating — that studio. You are publishing a derivative of their image, and whether you need their permission depends on the contract it was produced under. Ask before you animate it, not after.
Label the status. "Competition entry, unbuilt" or "Concept design, not constructed" on screen, held long enough to read. An unbuilt scheme presented in motion is very easy to mistake for something that exists, and the general practice for generated material — synthetic media disclosure — applies on top.
Watch the title rules. In the US, use of "architect" and "architecture" in marketing is regulated by state licensing boards. If the film goes out under a brand that is not the licensed entity, or lists titles that do not match people's licensure, that is a compliance question rather than a marketing one.
Assembly, and what to do with the result
Cut it in the editor rather than in a generation. The segments are footage; the title cards, project data, credits and status label are typed layers over them, so a credit correction costs an overlay edit and not a re-render. The editor is timeline-based and re-renderable, the 480p preview pass is free with a short per-user cooldown so you can check pacing before committing, and the final export is charged once regardless of segment count. Nothing exports with a watermark on any plan, which matters for an awards submission.
Three places the finished piece earns its keep: the practice's project page, where an unbuilt scheme finally has something that holds attention; awards and publication submissions that accept moving image; and pitch decks, where sixty seconds of an unbuilt project communicates ambition faster than a board ever has. Video for architects covers the adjacent formats.
FAQ
Does this replace commissioning archviz?
No, and pitching it that way will damage your credibility with clients who know the difference. Archviz produces geometry-accurate, materially specified imagery that can be interrogated. This produces motion between images you already had. Use it for competition work, unsuccessful schemes, portfolio depth and social; commission properly for anything a client will decide on.
What if the model changes the building between keyframes?
Reject the segment and shorten the interval. Most drift comes from asking the model to travel too far between two views — a wide site shot to a tight interior is several moves' worth of change, and the model fills the gap by inventing. Insert an intermediate keyframe and generate two shorter segments.
Can we animate a render produced by an external visualisation studio?
Check the contract first. The render is their work, delivered under specific terms, and producing a derivative may or may not be within them. Where the terms are unclear, ask — most studios would rather be credited than surprised. Where you cannot get an answer, animate a frame you produced in-house.
How long should the finished piece be?
Sixty to ninety seconds for a portfolio or awards cut. Fifteen to twenty for social, built from the two strongest segments plus a title. Do not make one file serve both — the pacing that lets a jury read a section loses a feed viewer in three seconds.
