Video Generation

AI video generation just learned a new word: "direction."

Until now, AI video tools let you set a start frame and an end frame at best — everything in between still had to be patched together by hand in an editor. Luma AI's new Ray3.2 model breaks that ceiling by letting you place up to 16 keyframes in a single clip.

BEFORE: START + END ONLY start end middle fixed by hand in an editor RAY3.2: UP TO 16 POINTS camera and framing set directly at each point

The Bottleneck

Stuck with clips that
"kind of" looked right

For the past few years, AI video generation moved from text prompts to, at best, a start and end image. Runway went a long time without a native end-frame input at all, and Kling 3.0 only recently added start/end two-point control. Getting the exact cut you wanted still meant pulling generated footage into an editor and reassembling it by hand.

Luma AI's Ray3.2, released June 9, 2026, changes that premise. A single clip can now hold up to 16 keyframes, each one setting camera angle and composition directly, with the model interpolating the motion in between. It's the shift from a tool that "kind of" shoots what you meant to one you can actually direct.

How It Works

Place the points,
let the model fill the gaps

The mechanics are simple. Drop up to 16 anchors on the timeline, each describing what the shot should look like at that moment, and Ray3.2 interpolates the motion between them into one continuous clip.

01

Place the anchors

At any point on the timeline, set up to 16 keyframes specifying composition, camera position, and subject pose.

02

The model interpolates

Ray3.2 smoothly generates the motion between adjacent keyframes. Denser keyframes get you closer to the exact camera move you had in mind.

03

Export as HDR/EXR

Output supports native HDR generation and can be exported as 16-bit EXR, feeding AI-generated footage directly into professional color-grading tools like DaVinci Resolve.

From writing a prompt
to directing a timeline.


04
In Practice

Who it helps, and how

Video producers & designers

You can match a storyboard's shot list without post-hoc fixes. The trade-off: the more keyframes you use, the closer you get to what you intended, but designing the point layout itself takes practice.

Marketers

Ad and social clips can hit the exact composition you wanted at the exact moment. That said, it's overkill to design 16 points for a five-second vertical clip — the payoff scales with the length of the piece.

Engineers

Ray3.2 is available as an API for the first time, so it can be embedded directly into your own product. Work that previously had to go through Luma's app can now be automated as a feature of your own SaaS.


05
Frontier & Risks

Not without caveats

With Ray3.2, the achievable precision of AI video control jumped from a two-point start/end pair to as many as 16 points — that much is confirmed. But this is one move in a race where Sora, Kling, and Veo are all pushing toward the same goal: getting past prompt-only control into frame-level direction. The number 16 shouldn't be read in isolation from that competition.

Practical limits remain, too. Designing 16 keyframes is meaningfully more work than typing a single prompt. Generation is also billed on a credit basis that scales with resolution and duration, so longer, higher-resolution projects could cost more than expected. This isn't "the editor becomes unnecessary" — it's closer to "part of editing moves earlier, into timeline design."
