Luma AI for architecture: Ray3.2 keyframes, Modify Video, Reframe and pricing for rendering videos
Luma AI for architecture: what Ray3.2's 16 keyframes, Modify Video and Reframe do with renderings, where buildings drift, credit costs and a workflow.
In this article
Luma AI is often recommended for architecture because its video model handles light and camera movement well, but much of the advice online still refers to Dream Machine, a name Luma has retired. The current model is Ray3.2, and it brings three tools that matter to a design studio: up to 16 keyframes in one clip, Modify Video for restyling footage you already have, and Reframe for changing a clip's aspect ratio. This guide covers what each does with renderings as of October 2026, where buildings still drift, what Luma's plans and credits cost, and a workflow for one project.
Key takeaways
- Luma's current video model is Ray3.2, released in June 2026, used in the Luma App; Luma calls Dream Machine an older, deprecated name.
- Ray3.2 makes 5- or 10-second clips from an image or text at up to 1080p, in ratios including 9:16, and lets you set up to 16 keyframes inside a single clip.
- Modify Video reshapes existing footage up to 20 seconds at 1080p, which suits a walkthrough exported from your renderer more than a single still.
- On Luma's pricing page a 5-second 1080p clip costs 400 credits, so the Plus plan's 10,000 monthly credits cover about 25 such clips before retries.
- Keyframes pin the views you supply, but the frames between them are still invented, so review window counts, verticals and frame edges in every clip.
Is Luma AI good for architecture?
Luma AI is a good fit for architecture when you want to steer a camera move across several views of one design. Ray3.2 turns a rendering into a 5- or 10-second clip at up to 1080p, supports 9:16, and lets you pin up to 16 keyframes inside one clip, so the move can pass through views you approved. Like every clip tool, it leaves the prompts, the review of each clip, the edit and the music to you.
It is also one of the few tools with a strong answer for footage you already have. If your renderer produced a correct but flat walkthrough, Modify Video and Reframe can change its look or its aspect ratio without touching the camera path.
Luma's current tools, as of October 2026
Luma's information page says the company is called Luma, the brand Luma AI, and the product the Luma App; it describes Dream Machine as "an older deprecated model replaced by Ray" and lists Ray3.2, released in June 2026, as the current video model. The Ray page describes four modes.
| Mode | What it does | Length | Use in architecture |
|---|---|---|---|
| Image-to-video | Animates a still from a prompt | 5 or 10 s | A rendering or photo becomes one shot |
| Text-to-video | Generates a clip from a prompt only | 5 or 10 s | Mood studies, not your design |
| Modify Video | "Reshapes footage you already have" | Up to 20 s at 1080p | Restyle a renderer walkthrough or a site clip |
| Reframe | "Handles every aspect ratio" | Up to 12 s | Turn a 16:9 clip into a 9:16 one |
Luma lists output at 360p (as a draft), 540p, 720p and 1080p, in 9:16, 3:4, 1:1, 4:3, 16:9 and 21:9, and offers native 16-bit color with 16-bit EXR frames for color grading and compositing, all as of October 2026. EXR export matters if your visualization team grades or composites in post; for a social post, 1080p SDR is enough.
Keyframes: pinning a camera move to your renderings
The Ray page says "Multi-Keyframe lets you set up to 16 keyframes inside a single clip." For a building, keyframes are the closest thing to a camera path a clip tool offers. Instead of letting the model extrapolate from one image, you give it the views it must pass through.
Used well, it looks like this: a street-level view of the entrance as the first keyframe, a view a few steps closer as the second, and the open door as the third, all rendered from the same model with the same light. The model fills in the frames between views that already agree with each other, and has far less room to invent a different canopy or a different door.
Used badly, it looks like six unrelated hero images strung together. If one keyframe is an exterior and the next a kitchen, the model has to invent how the camera got inside, and it will create a doorway or a corridor that is not in your design. Two practical rules:
- Keyframes from one model, one lighting setup. Mixed render engines or times of day turn into a flicker between keyframes.
- Small steps between views. The closer two keyframes are in camera position, the less the model invents between them.
AI video prompts for architecture ranks camera moves by how well they keep verticals straight, which still applies between keyframes.
Camera moves and motion transfer
The Ray page also promises that you can "transfer cinematic camera moves across scenes, worlds, and styles," and the information page lists motion transfer among the app's capabilities. For a studio, the useful version is borrowing a move you like, such as a slow rising crane shot from a real drone clip, and applying it to a rendering. Treat it as something to test on your own images: the move transfers, but the model still has to invent whatever the borrowed path reveals beyond your rendering's frame. A rising move over a roof will show a roof the rendering never drew.
Modify Video and Reframe on footage you already have
This is where Luma can be most useful to architects. A walkthrough exported from Enscape, Lumion, Twinmotion or D5 follows your actual geometry, so the camera path is right even when the look is flat. Modify Video changes the look while keeping the footage; Luma's words are "The lighting holds. The performance survives. Up to 20 seconds, all at 1080p." Reframe changes the aspect ratio, which is a quick route from a horizontal presentation walkthrough to a vertical Reel. If you have not exported one yet, vertical export from Enscape, Lumion, Twinmotion or D5 covers the settings.
Luma names the footage Modify Video handles poorly: "heavy camera shake, whip-fast or chaotic action, blurry/dark/low-res footage." Smooth, well-lit renderer output is close to the ideal input. Phone footage of a finished project is fine if it is stabilized. Whatever you modify, compare the result with the original at the same frame, because a restyle can quietly change a material or a window pattern.
Where buildings drift in Luma
| What drifts | Where you see it | How to reduce it |
|---|---|---|
| Window and bay counts | Long facades during lateral moves | Slower moves; keyframes at both ends |
| Vertical lines | Wide-angle exteriors | Two-point perspective source images |
| Invented context | Orbits and rising moves | Keep the path within what the image shows |
| Furniture and objects | Living rooms, lobbies, kitchens | Shorter clips; prompt for an unchanged room |
| Reflections | Glass, mirrors, polished stone | Avoid moves that sweep across reflective surfaces |
| Lettering | Signage, house numbers | Remove it from the source image |
None of this is particular to Luma. An image-to-video model reads pixels and infers depth; it never saw your plans. Review every clip at full screen against the source image, and present unbuilt work as concept work.
What Luma costs, as of October 2026
Luma's pricing page lists three individual plans with commercial use, plus Team and Enterprise plans on request. The pricing page lists no free plan.
| Plan | Monthly | Billed yearly | Credits per month |
|---|---|---|---|
| Plus | USD 30 | USD 25 a month (USD 300 a year) | 10,000 |
| Pro | USD 90 | USD 75 a month (USD 900 a year) | 40,000 |
| Ultra | USD 300 | USD 250 a month (USD 3,000 a year) | 150,000 |
Video costs depend on resolution and length. For Ray3.2, the same page lists:
| Resolution | 5-second clip | 10-second clip |
|---|---|---|
| 360p (draft) | 20 credits | 60 credits |
| 720p | 100 credits | 300 credits |
| 1080p | 400 credits | 1,200 credits |
The Ray page adds that HDR costs twice the SDR credits, and HDR with EXR frames three times. A practical project budget: test camera moves at 360p (six clips, 120 credits), then generate the six keepers at 1080p (2,400 credits), then allow for re-rolling half of them (another 1,200). That is about 3,700 credits, comfortably inside Plus, before editing, music and captions.
Luma clips or a six-image film
Luma is the better choice when you want specific camera moves, need a format other than vertical, or want to restyle a renderer walkthrough without re-rendering. It is more work than it looks when the goal is a single 30-second vertical film of one project: six or more clips to direct, review and assemble, and a licensed soundtrack to add.
For that job, Arch2Video takes exactly six images from one project and returns a 1080 × 1920 MP4 of about 30 seconds: six connected five-second scenes with an original soundtrack, for USD 15 per video as a one-time payment. There is no prompt or keyframe control, the AI director picks the scene order, and every film includes a small cast of fictional adults in at least one scene. The Runway for architecture guide and the comparison of AI video generators for architects cover the other clip tools.
Frequently asked questions
Is Dream Machine the same thing as Luma AI?
Dream Machine was Luma's earlier product and model name. As of October 2026, Luma's own information page calls Dream Machine "an older deprecated model replaced by Ray," names the current app the Luma App, and lists Ray3.2 as the current video model. Tutorials that mention Dream Machine settings may not match what you see today.
Can Luma make a vertical 9:16 video from a horizontal rendering?
Yes, in two ways. You can generate directly in 9:16 from the rendering, in which case the model recomposes the frame and invents what lies above and below the original, or you can generate in the original ratio and use Reframe, which Luma says "handles every aspect ratio," on clips up to 12 seconds. Either way, check the newly visible areas: they are generated, not taken from your design.
Which resolution should I use in Luma for an Instagram Reel?
Test at 360p or 720p, then render the final clips at 1080p. As of October 2026 a 5-second clip costs 20 credits at 360p, 100 at 720p and 400 at 1080p on Luma's pricing page, so drafting low is the cheapest way to find a camera move that holds the building. 1080p is the highest resolution Luma lists and the one to use for a final vertical post; rendering export settings for Instagram covers the rest of the file.
Can I use Luma videos in client marketing?
Luma's pricing page lists commercial use on the Plus, Pro and Ultra plans as of October 2026. That covers the output, not the inputs, so only animate renderings and photos you have the right to use, check your client agreement before uploading unreleased designs, and label AI-generated concept work as such in the caption.
