Write your prompt — describe the subject, setting, action, camera movement, lighting, and mood you want.
Choose size — select the aspect ratio that fits your target platform or layout.
Choose resolution — use 540p for the lowest cost, 720p for a middle option, or 1080p for the highest quality.

Add references (optional) — include references if you want extra control over visual direction.
Submit — run the model and download the generated video.

Example Prompt

A cinematic post-apocalyptic video of a tired father carrying his little daughter through an abandoned city street at sunrise. Broken cars, overgrown plants, and ruined buildings surround them. The daughter wakes up and points at a small butterfly landing on a cracked traffic light. The father stops, smiles faintly for the first time, and gently lowers her to watch it. The camera follows them from behind, then slowly circles to reveal their faces. Warm sunrise light, dust in the air, realistic survival drama.

Pricing

Pricing depends on duration and resolution.

Duration	540p	720p	1080p
5s	$0.50	$1.00	$2.00
10s	$1.00	$2.00	$4.00

Billing Rules

Base price is $0.50 for a 5s video at 540p
10s costs 2× the 5s rate
720p costs 2× the 540p rate
1080p costs 4× the 540p rate
Pricing depends only on duration and resolution

Best Use Cases

Cinematic scene generation — Create short dramatic or emotional video moments from prompts.
Trailer concepts — Prototype story beats and visual sequences quickly.
Social media content — Generate short-form video ideas for vertical or widescreen publishing.
Advertising concepts — Build mood-driven commercial shots before full production.
Creative previsualization — Test scene direction, pacing, and camera ideas.

Pro Tips

Be specific in your prompt about subject motion, camera movement, lighting, and emotional tone.
Use 5s for fast concept validation, then switch to 10s when you need more scene development.
Start with 540p or 720p for testing and move to 1080p for higher-end final outputs.
Add references only when you need stronger visual steering.
Keep prompts focused on what should happen in the clip rather than listing unrelated visual details.

Notes

prompt is required.
duration currently supports 5s and 10s.
Pricing depends only on the selected duration and resolution.
Reference input is optional.

How do I call the Ray 3.2 Text To Video API?

POST your input parameters to the model's REST endpoint (shown in the API tab of this playground) with your WaveSpeedAI API key in the Authorization header.

How much does Ray 3.2 Text To Video cost per run?

Ray 3.2 Text To Video starts at $0.50 per run. That figure is the base price — the final charge scales with the parameters you set in the form (output size, length, count, references, or whatever knobs this model exposes), so a higher-quality or larger output costs more than a minimal one. The exact cost for your current input is shown live next to the Generate button before you submit, and the actual per-call charge is recorded on the prediction afterwards.

What inputs does Ray 3.2 Text To Video accept?

Key inputs: `prompt`, `resolution`, `duration`, `size`, `reference`. The full JSON schema (types, defaults, allowed values) is rendered above the Generate button and mirrored in the API reference at https://wavespeed.ai/docs/docs-api/luma/luma-ray-3.2-text-to-video.
