Sora Prompt Generator
Video prompts fail for a different reason than text prompts: they describe a picture instead of a moving shot. Describe what you want and PromptVibe writes the Sora prompt with the motion, camera and lighting spelled out — free, no account needed.
A Sora prompt generator turns a plain description into a shot specification: subject, what moves, how the camera moves, the lighting, the setting and the shot length. Video models render motion, so a prompt that only describes a still scene produces a clip that looks static and drifts.
How Sora prompts differ
- Motion is the subject, not a detail: A still-image prompt describes what a frame contains. A video prompt has to say what changes across the clip — the person turns, the leaves move, the light shifts. If nothing is specified as moving, the model has to invent motion, and invented motion is where clips go wrong.
- Camera language does real work: Terms like slow dolly in, static wide shot, handheld tracking shot, low-angle, and rack focus are unambiguous instructions about how the frame behaves. Naming one is the difference between a shot you planned and a shot you got.
- Duration changes what fits: A short clip holds one beat. Asking for a three-part narrative in a few seconds forces the model to compress and the result reads as a jump cut. State the shot length and give it one thing to do.
- Style has to be described, not named: Naming a film or director is vague and inconsistent. Describing the look — shallow depth of field, 35mm grain, overcast diffused light, muted palette — is concrete and repeatable.
Techniques that work
- Lead with the shot, not the story. Open with the subject and framing ("A close-up of a potter's hands shaping wet clay"), then layer motion, camera, lighting and setting. Front-loading the visual anchor gives everything after it something to attach to.
- Separate subject motion from camera motion. These are two different things and models conflate them. Say both: "the potter's hands keep turning the clay (subject); the camera slowly pushes in (camera)."
- Describe light by quality and direction. "Warm side light from a window on the left, soft shadows" gives the model something to render. "Nice lighting" does not.
- Say what should not happen. Explicit exclusions — no text overlays, no cuts, no camera shake — remove the most common unwanted behaviours before they appear.
Example Sora prompts
Product shot — Descriptive video prompt
A close-up of a matte black coffee grinder on a concrete counter, fresh beans falling into the hopper. Subject motion: beans tumble and settle; a thin wisp of steam drifts from a cup just out of frame. Camera: slow dolly in, ending at a tight three-quarter view. No shake. Lighting: soft window light from the left, deep but not crushed shadows. Style: shallow depth of field, 50mm look, muted warm palette, subtle 35mm grain. Duration: one continuous 5-second shot, no cuts. Avoid: text overlays, logos, people.
Establishing shot — Descriptive video prompt
A wide establishing shot of a small fishing harbour at dawn, boats at anchor, mist on the water. Subject motion: boats rock gently; mist drifts right to left; one gull crosses the frame. Camera: static wide shot on a locked-off tripod. Lighting: low golden sunrise from behind the boats, long reflections on the water. Style: natural colour, high dynamic range, no stylisation. Duration: one continuous 8-second shot. Avoid: cuts, zooms, text, modern signage.
Character moment — Descriptive video prompt
A medium shot of an older woman reading a letter at a kitchen table, her expression shifting from puzzled to quietly pleased. Subject motion: she lowers the letter slightly and looks up past the camera; a small smile forms. Camera: handheld, very slight float, no whip pans. Lighting: overcast daylight through a window behind her, face fill from a bright wall. Style: documentary realism, natural skin tones, no colour grade. Duration: 6 seconds, single take. Avoid: dialogue, subtitles, dramatic music cues, cuts.
Test it before you trust it
A prompt that reads well is not the same as a prompt that works. The Compare AI Lab runs the same prompt through up to three models side by side so you can see which one actually handles your task, and the A/B tester scores two versions of a prompt against criteria you choose. Free members get a comparison every day.
Limitations
- PromptVibe is an independent tool and has no affiliation with OpenAI or Sora.
- A well-structured prompt improves consistency; it cannot guarantee a specific clip.
- Video model behaviour, available durations, and access change over time — check the vendor's current documentation.
Frequently asked questions
What makes a good Sora prompt?
A good video prompt names five things: the subject and framing, what moves in the scene, how the camera moves, the lighting quality and direction, and the shot length. Adding an explicit "avoid" line for text overlays and cuts removes the most common unwanted behaviours.
Why does my video look static?
Almost always because the prompt describes a picture rather than a shot. If nothing is stated as moving, the model has to invent motion. Name one clear subject movement and one camera movement and the clip gains direction.
Should I name a film or director for style?
Describing the look is more reliable than naming a reference. "Shallow depth of field, 35mm grain, overcast diffused light, muted palette" is something a model can render consistently; a director's name is interpreted differently every time.
Is this an official OpenAI or Sora tool?
No. PromptVibe is independent and has no affiliation with OpenAI. It generates structured prompts you can use with Sora and other video models.
