Generate cinematic videos with synchronized audio from a text prompt.
Seedance 2.5 Text to Video 480p generates cinematic clips from a written prompt at 480p — the budget-friendly, fast-iteration tier of Seedance 2.5 text-to-video. Turn one prompt into a 4–30-second clip with optional synchronized native audio. This page accepts text only; move to the 720p page when you need sharper finals.
| Advantage | What it means for you |
|---|---|
| Cheaper, faster drafts | 480p output at $0.17/s lets you explore prompts, batch variants, and review ideas before committing to a higher-resolution final. |
| Native audio in one pass | Generate synchronized speech, sound effects, and music with the video, or turn audio off for silent clips. |
| Up to 30-second clips | Direct a longer single shot with a clear beginning, development, and ending. |
| Prompt-driven control | Follow negative and timestamp-style instructions more reliably for timed actions, framing, and multi-language scenes. |

| Parameter | Required | Type | Default | Range / Options | How to choose |
|---|---|---|---|---|---|
prompt* | Yes (*) | String | Example prompt | Chinese ~≤500 characters or English ~≤1000 words recommended | Give a structured brief: subject, one main action, camera, setting and lighting, visual style, and any audio. |
aspect_ratio | No | String | 16:9 | 16:9, 9:16, 1:1, 4:3, 3:4, 21:9, adaptive | Match the destination frame; adaptive lets the model pick the closest ratio. |
duration | No | Integer | 5 | 4–30 seconds, in 1-second steps | Short clips for a single action; longer only when the prompt defines a clear beginning, development, and ending. |
generate_audio | No | Boolean | true | true / false | Leave on for synchronized speech, effects, and music; turn off for silent video. |
\* Required field. This page has no image, video, or audio reference inputs.
Seedance 2.5 Text to Video 480p is billed per second of generated video at a fixed 480p:
| Duration | Price at $0.17/s |
|---|---|
| 5s | $0.85 |
| 10s | $1.70 |
| 15s | $2.55 |
| 30s | $5.10 |
For batches of multiple outputs, calculate the total as duration × $0.17 × output count.
Use this reusable prompt structure:
[subject + defining details] + [one action over time] + [camera framing and movement] + [setting + lighting] + [visual treatment] + [dialogue / effects / ambience / music] + [ending frame or constraint]

> Pacific Coast Highway at golden hour, a vintage red convertible driving along a cliffside road above the ocean, warm low sun rim-lighting the car and wet asphalt, soft coastal mist rolling inland, sun glitter on the waves below, medium tracking shot gliding parallel to the car then a gentle push-in, cinematic anamorphic look, shallow depth of field, smooth continuous motion, no text, no watermark.

Seedance 2.5 Text to Video 480p turns a written prompt into a 480p clip with optional native audio. It fits draft passes, social variants, and high-volume prompt trials where speed and cost matter more than final sharpness.
Both take a text prompt only; the 480p page outputs at 480p ($0.17/s) for cheaper, faster iteration, while the 720p page ($0.35/s) is better for polished deliverables. Many teams draft here, then rerun the winning prompt at 720p.
Video is output at a fixed 480p. Aspect ratio can be 16:9 (default), 9:16, 1:1, 4:3, 3:4, 21:9, or adaptive (the model picks the closest ratio). Duration is a whole number of seconds from 4 to 30, with a default of 5.
No. This page is text-only: scene, motion, lighting, and camera direction all come from the prompt. Its API accepts only prompt, aspect_ratio, duration, and generate_audio. If you need reference-driven control, use the Seedance 2.5 image-to-video, reference-to-video, or first-and-last-frame pages.
Yes. generate_audio is on by default, so the model can output synchronized speech, effects, and music. Turn it off when you only need silent video.
Yes. Prototype in the RunComfy model UI, then call the same template through the API with matching fields (prompt, aspect_ratio, duration, generate_audio). Generations consume credits on both paths.
It is billed at $0.17 per second of generated video. A 5-second clip costs about $0.85; longer durations scale linearly with the length you select.
Stay on 480p for drafts, batch variants, and early creative reviews. Move to the 720p Seedance 2.5 text-to-video page when you need sharper finals for ads, client delivery, or platforms that favor higher resolution.
