Image to Video00:00:05:00Toward the camera, busy street
Runway Gen-4.5 · 5s
“She keeps walking toward the camera through the busy street, her smile growing slightly. Pedestrians drift past on both sides. The camera pushes in very slowly. Warm low sun, natural motion, no camera shake.”
Image to Video00:00:05:00Shaping the figure
Runway Gen-4.5 · 5s
“Her hands work slowly on the clay figure, shaping it with small steady movements. Dust drifts through the window light. She tilts her head slightly as she studies the form. Calm, unhurried motion, locked-off camera.”
Image to Video00:00:05:00Laughing over coffee
Runway Gen-4.5 · 5s
“She laughs, then lowers the cup slightly and settles into a warm smile. Leaves shift in a light breeze behind her and the dappled sunlight moves across the table. Gentle, natural motion, locked-off camera.”
Image to Video00:00:05:00Along the horizon
Runway Gen-4.5 · 5s
“Wind moves her hair across her shoulder. She blinks and her gaze drifts slowly along the horizon. Waves roll in softly behind her and the light shifts. Very slow, quiet motion, locked-off camera.”

Text to Video00:00:04:00Dunes at dawn
Runway Gen-4.5 · 4s
“A wide shot of vast sand dunes at dawn, long shadows raking across the ridges while fine sand streams off the crests in a light wind. Warm gold and deep violet shadow, very slow push-in, no people, no camera shake.”
Text to Video00:00:04:00The platter from above
Runway Gen-4.5 · 4s
“A top-down overhead shot looking straight down at a turntable playing a record. The whole platter, the spinning black disc and the tonearm are in frame from directly above, the paper label turning steadily at the centre. Warm side light across a wooden surface, locked-off overhead camera, minimal motion, no people.”
Text to Video00:00:04:00Linen on the line
Runway Gen-4.5 · 4s
“A wide shot of white linen sheets hanging on a washing line in warm afternoon sun, lifting and settling gently in a light breeze while the light glows through the fabric. A quiet courtyard and a stone wall behind, soft shadows, locked-off camera, slow unhurried motion, no people.”
● Vertical
Built for the tall frame
Some shots only work standing up. Same model, same controls, no re-shoot.
Text to Video00:00:04:00Down the mossy face
Runway Gen-4.5 · 4s
“A vertical shot of a tall narrow waterfall falling down a dark mossy rock face, the water breaking into mist before it reaches the pool below. Cool green light through wet foliage on both sides, fine spray drifting across the frame, locked-off camera, steady continuous motion, no people.”
Text to Video00:00:04:00Rain on the glasshouse
Runway Gen-4.5 · 4s
“A vertical shot from inside an old glasshouse during rain. Water runs down the glass roof above and mist clings to the panes, while broad green leaves fill the lower frame. Soft grey daylight, deep greens, very slow drift, no people, no camera shake.”
Text to Video00:00:04:00Tail lights on wet asphalt
Runway Gen-4.5 · 4s
“A vertical shot of a vintage saloon car driving slowly away down a wet city street at dusk, seen from behind, its tail lights smearing on the rain-slicked asphalt while lit shopfronts slide past on both sides. Deep greens and warm amber, steady slow following camera, no people visible.”
● On the job
Four shots a brief actually asks for
Product beat, clean plate, establisher, insert. The four that fill a cut.
The turning light
Verbatim prompt
A slow turning light across a tan leather holdall standing on a lit studio plinth, the grain and stitching catching the highlight as it travels. Deep shadow behind, warm key from the left, locked-off camera, minimal motion.
Nothing in the way
Verbatim prompt
A locked-off shot of an empty rooftop at dusk, gravel and a low parapet in frame, the sky shifting slowly behind. Nothing moves but the light and a thin drift of cloud. No people, no camera shake, clean and uncluttered.
The city takes its light
Verbatim prompt
A very slow drift across a city skyline at blue hour, windows lighting up in sequence across the towers as the last daylight drains from the sky. Cool blues and warm window gold, no people, no camera shake.
Syrup, still running
Verbatim prompt
The maple syrup keeps running slowly down the sides of the stack and spreading on the plate, while the pat of butter melts and settles into the top pancake. Faint steam drifts upward. Everything else stays perfectly still. Locked-off camera, minimal unhurried motion.
The lobby at dusk
Verbatim prompt
A very slow drift through a quiet modern hotel lobby at dusk, warm pools of lamp light across stone and dark timber, tall windows holding the last blue outside. No people, no camera shake, calm continuous motion.
Light across the weave
Verbatim prompt
A macro shot of light raking slowly across a swatch of coarse natural linen, every thread and slub picking up the highlight as the light travels. Warm neutral tones, shallow depth of field, locked-off camera, minimal motion.

● Questions
Frequently asked questions
Runway Gen-4.5 is Runway's continuity-first video model, and on OpenClips it renders silent takes of 2 to 10 seconds. You define world references once, and characters, locations and styles hold across shots. Renders start at ⚡46 and the composer quotes the exact cost before anything runs.
No. Runway Gen-4.5 renders silent video. Add music or voice in your editor afterwards, or send the same brief to Veo 3.1 or Kling 3.0 in the same composer for a take with sound in one pass. Both share your wallet and your library.
The composer offers 2, 4, 6, 8 or 10 seconds per render. Ten seconds covers a hook, a product beat and a look to camera. For a longer sequence, render several shots against the same world reference and cut them together. The exact ⚡ shows before each one.
A world reference is Runway shorthand for a character, location or style you want to keep across shots. Define it once at the top of the composer, then call it from every shot in that world. Faces, wardrobe and light hold. The model does not re-cast each take.
Not on Gen-4.5. The model publishes no resolution tiers to OpenClips, so there is no dropdown to set and no cheaper rung to draft on. What you choose instead is the length and the frame: 2 to 10 seconds, in 16:9, 9:16, 21:9, 4:3, 3:4 or 1:1. Price follows length alone.
Gen-4.5 when the shot starts from a prompt and one still. Aleph 2 when it starts from footage you already shot: it restyles up to 30 seconds of your own clip and holds up to 5 references, at ⚡3 per second. Both sit one chip apart in the same composer.
It starts at ⚡46 for the shortest take and climbs with seconds, because length is the only axis this model prices on. A free account opens with ⚡50 to try the roster on cheap settings. Packs start at $10/1,000⚡. The composer prices your exact render before it runs.

One world, held across every shot
Gen-4.5 carries world references. Name your characters, locations and styles once, and they persist from take to take. For a campaign or a series, that is the whole game.
It is the model you hand a team that has to deliver the same world forty times. Predictable, controllable, editing-native. For per-frame prompt control Seedance 2.5 leads. For sound in the same pass, Veo 3.1 or Kling 3.0 own the room.
Where the take stops
Takes run 2 to 10 seconds, and the composer offers them as chips: 2s, 4s, 6s, 8s, 10s. Ten seconds is enough for a hook, a product beat and a look to camera. There is no resolution dropdown on Gen-4.5. Longer sequences are several takes against one world reference, cut together in your editor.
When Aleph 2 fits better
Gen-4.5 starts from a prompt and one still. Runway Aleph 2 starts from footage you already shot, restyles up to 30 seconds of it, and holds five references while it does. Same wallet, same library, one chip apart in the composer.
One composer, one wallet
Every take lands in the same library, whatever model made it. Browse the whole roster on the models hub, or start from the AI Video Generator and switch models without moving your prompt.
