This is the fast reference for writing Luma Ray3 prompts in Dream Machine — the reasoning-driven 2026 video model (latest Ray3.14), also available in Adobe Firefly. Ray3 reads plain English literally, so there is no bracket or director syntax to memorize. Keep this open in a tab, copy the pieces you need, and assemble a shot with the formula below.

The Luma prompt formula

Write one clear, specific sentence in this order and Ray3 gives you a controllable clip. Everything stays in natural language — no tags, no brackets. Ray3 reads every word literally, so be concrete and keep to one main action.

Subject + Action + Scene + Camera movement + Style/Mood.

A barista pulls an espresso shot in a sunlit cafe, steam rising over polished brass, slow dolly in, warm morning window light, shallow depth of field, cinematic.

Match each element to a row in the tables below. Skip an element and Ray3 fills the gap for you — usually with something generic — so specify what matters to your shot. English is the most stable language for prompts.

Shot sizes

Shot size sets how much of the subject fills the frame. Pick one and name it early in the sentence.

Shot sizeFramesUse it for
extreme wideTiny subject in vast spaceLandscapes, scale, establishing
wideFull subject plus environmentContext and action
mediumWaist upDialogue, product-in-hand
medium close-upChest upEmotion with some setting
close-upFace fills the frameExpression, reaction
extreme close-up / macroEyes, mouth, one detailTension, texture, product macro

Camera moves

Describe the move in plain words inside the sentence. Ray3 renders natural-language motion — keep it to one main move so the reasoning stays clean.

PhraseEffect
dolly in / dolly outCamera drives toward or away from the subject
truck left / truck rightSlide the whole camera sideways
crane up / crane downSweep the camera high or low on an arm
pedestal up / pedestal downRaise or lower the camera straight vertically
orbit / arc around the subjectCircle the subject to reveal dimension

handheld push-inOrganic, slightly shaky move toward the subject
pull backRetreat to reveal wider context
whip panFast blurred turn between beats
overhead top-downBird's-eye view looking straight down
static / locked-offNo camera movement at all

Lighting & style

Lighting and grade set the mood. Add one or two cues near the end of the sentence for a cinematic feel.

Settings quick-reference

Choose these in the app or API, not in the prompt text. Draft Mode is the one to remember for iteration — render cheap, then upgrade the keeper.

SettingOptions & rules
Aspect ratio9:16, 3:4, 1:1, 4:3, 16:9, 21:9. Match to where the clip will play.
DurationText-to-video 5s or 10s; image-to-video 5s; Modify ~18s; Extend ~30s.
Resolution540p, 720p, native 1080p (Ray3.14); 4K via upscale.
Quality tierDraft for fast, cheap iteration; Hi-Fi for the final render.
AudioNone — Ray3 outputs silent video. Add sound in an editor.

Features & modes

Ray3 in Dream Machine covers the full pipeline from a single still to a finished, extended clip. Pick the mode that matches your starting point.

ModeWhat it does
Text-to-videoGenerates a clip from a written prompt (5s or 10s).
Image-to-videoAnimates a single still into a 5s clip.
KeyframesInterpolates motion between a start frame and an end frame.
ModifyVideo-to-video restyle that preserves the original motion (~18s).
ExtendContinues a clip from its last frame, out to ~30s.
LoopRenders a seamless repeating loop.
Character ReferenceHolds a consistent character across shots.
HDRNative 16-bit HDR output (ACES EXR, 10/12/16-bit).
Draft Mode~5x faster, ~5x fewer credits; then "Upgrade to Hi-Fi".

Things to avoid

These are the common mistakes that break a Ray3 shot, with the fix for each.

AvoidFix
Contradictions in one promptRay3 reads literally — drop conflicting cues like "static shot, fast orbit"

Example prompts

Six complete prompts built with the formula. Copy, swap the subject, and set the output options in the app.

1. Cinematic b-roll

Morning fog drifts through a pine forest, thin sunbeams cutting between the trunks, dew on the ferns, slow dolly in, wide shot, golden hour, cinematic.

A slow dolly into a wide establishes the space. (16:9, 1080p, 10s, Hi-Fi)

2. Product hero

A matte black wireless earbud case rests on wet slate, water beading on the lid, light sweeping slowly across the surface, extreme close-up, orbit around the case, hard backlight, shallow depth of field.

Best rendered as image-to-video from a product still to lock the shape. (1:1, 1080p, image-to-video 5s)

3. Action tracking shot

A trail runner sprints down a rocky coastal path, dust kicking up behind, ocean crashing below, wide shot, handheld push-in tracking shot, bright overcast light, filmic grain.

A handheld tracking push keeps the runner centered with kinetic energy. (16:9, 720p, 10s, Draft first)

4. Vertical social clip

A young chef plates a dessert in a modern kitchen, powdered sugar drifting down, medium shot, pedestal up reveal, warm soft window light, shallow depth of field, appetizing.

A rising pedestal reveal reads well in a 9:16 feed. (9:16, 1080p, 5s)

5. Keyframe interpolation

A closed wooden door slowly opens to reveal a sunlit garden beyond, dust motes in the light, medium shot, static, soft window light, cinematic.

Set a closed-door start frame and an open-door end frame; Ray3 interpolates the swing. (4:3, 1080p, Keyframes)

6. Moody portrait

A woman sits by a rain-streaked window and slowly turns her head, rain running down the glass behind her, close-up, static locked-off, blue hour, hard backlight rim, filmic grain.

The clip is silent — add room tone and voiceover in an editor. (3:4, 1080p, HDR)

Once these feel natural, level up with our realistic-video guide and the cinematic b-roll set.

Frequently Asked Questions

Does Luma Ray3 use bracket or director syntax for camera moves?

No. Ray3 reads plain natural language and takes every word literally. Write camera moves as phrases like slow dolly in or orbit around the subject inside the sentence — no brackets or tags are needed.

What is Draft Mode in Luma Dream Machine?

Draft Mode renders about 5x faster and uses roughly 5x fewer credits, so you can iterate cheaply. When a take looks right, use Upgrade to Hi-Fi to re-render it at full quality.

How long can Luma Ray3 clips be?

Text-to-video runs 5 or 10 seconds and image-to-video runs 5 seconds. Modify holds about 18 seconds, and Extend pushes a clip to roughly 30 seconds by continuing from the last frame.

What resolutions and aspect ratios does Ray3 support?

Ray3.14 renders 540p, 720p, and native 1080p, with 4K available through upscale. Aspect ratios include 9:16, 3:4, 1:1, 4:3, 16:9, and 21:9.

Does Luma Ray3 generate audio?

No. Ray3 outputs silent video with no native audio. Add music, sound effects, or voiceover in an editor after the clip is generated.

What do Keyframes do in Dream Machine?

Keyframes let you set a start frame and an end frame, and Ray3 interpolates the motion between them. It is the cleanest way to control where a shot begins and ends.

How does Modify differ from image-to-video?

Modify is video-to-video: you feed in an existing clip and it restyles the frames while preserving the original motion, holding about 18 seconds. Image-to-video animates a single still into a new 5-second clip.
