Does the model actually render at a high frame rate?

Draft can render at 48 fps; Standard and Cinematic render at 24 fps and create the slow-motion look by stretching the action across the clip. For most uses the stretched look is what people mean by slow motion.

Can I slow down an existing video?

Not here. The site generates new clips from prompts or photos. Use photo animation with a still from your footage if you want a slow-motion version of a specific frame.

What subjects work best?

Liquids, powders, fabric, hair, sand and sparks. They have visible fine structure that reads as slow motion. Large rigid objects moving slowly tend to look like a slow camera move instead.

How many credits is a slow-motion hero shot?

A five-second Cinematic clip is sixty credits at 720p or one hundred and fifty at 1080p. A two-second Draft test at 48 fps and 720p is two credits.

Who owns slow-motion clips I render?

You do; the service assigns you any output produced at your direction, as described at /terms-of-service. Treatment of generated video under copyright differs by country, so consult a lawyer for your situation.

Slow motion from a prompt

Slow motion is a description, not a setting. Tell the model the action is unfolding slowly and the right tier will render the suspended droplets and drifting fabric that sell the effect.

Describing speed

The models respond to phrases like "ultra slow motion", "high-speed camera look" and "time stretched" by rendering the action across the full clip length instead of in a fraction of it. Pair the speed phrase with an action that is fast in real life, such as a splash, an impact, a flick of hair or a burst of powder, and the contrast is what reads as slow motion.

Be explicit about what should be suspended. "Grains of sand hanging in the air", "droplets frozen mid-splash" and "fabric billowing slowly" give the model specific things to stretch. Without them you may get a slow camera move over a normal-speed subject, which is not the same effect.

Why Cinematic is the slow-motion tier

Slow motion exposes detail. Droplets, individual hairs, fabric weave and particles are exactly the fine structures that cheaper models blur, and in slow motion they are on screen long enough for the blur to be noticed. The Cinematic tier keeps those structures intact frame to frame, which is why the slow-motion samples on this site were rendered there.

That said, run Draft first. A two-second Draft at 48 frames per second will tell you whether the action and camera are right. Draft is also the only tier with a 48 fps option, and its extra frames give a smoother slow-motion feel for simple subjects such as a bouncing ball or a swinging pendulum.

Draft 48 fps: smooth, cheap, good for simple shapes and tests
Standard 24 fps: fine for cloth and hair at modest detail
Cinematic 24 fps: droplets, particles, skin and sand

Lighting for suspended detail

Backlight and hard side light make particles and droplets visible; soft frontal light hides them. Ask for "backlit", "rim light", "hard side light" or "golden hour from behind" and the suspended material catches the light. A dark or plain background helps for the same reason, which is why so much real slow-motion advertising is shot against black.

Length and pacing

A slow-motion clip should hold one moment. Four to six seconds is usually enough for a splash or an impact; longer clips drift as the model runs out of action to stretch. If you want a longer piece, render the build-up at normal speed as one clip and the slow moment as another, then cut between them.

For a direct comparison of how each tier treats the same slow-motion prompt, queue Draft against Cinematic in compare mode. Watch the first second of each: the point where droplets begin to lose their edges is the point where the cheaper tier runs out of detail.

Freeze the moment

Describe a fast action, add "ultra slow motion", preview it on Draft at 48 fps, then render the keeper on Cinematic.
