ExamplesView all

One continuous unbroken shot, no cuts: A young female warrior stands in the center of an ancient Roman-style white marble courtyard, wearing dark leather armor and holding two short blades in a defensive stance. Several massive black wolf-like beasts slowly surround her from every direction, then suddenly leap toward her at the same time. She spins, ducks, blocks with crossed blades, and counterattacks in a fluid continuous motion, forcing the beasts back. The camera begins at a low angle near the ground, slowly pushes toward the warrior, then orbits halfway around her while passing through flying dust, sparks, and ash, ending in a close-up of her determined face. The beasts’ black fur whips violently with their movement, their fangs and claws clearly visible. Smoke rises in the courtyard, sunlight streams between the white marble columns, and dust floats in the light beams. Epic fantasy action film, realistic cinematic look, highly detailed, strong contrast, motion blur, intense battle choreography, widescreen composition, 8 seconds.

Seedance 2.0 Fast Spicy — Image-to-Video

Seedance 2.0 Fast Spicy generates unlimited high-quality cinematic clips from images at faster speed and lower cost than the standard Seedance 2.0 Spicy. It transforms static images into dynamic video with bold motion, rich tonal contrast, and stable temporal coherence — perfect for high-volume, iteration-heavy creative workflows.

Why It Works Well

  • Speed-optimized generation: Faster processing for quick turnaround.
  • 17% lower base cost than Seedance 2.0 Spicy.
  • Unlimited-style generation: Optimized for high-quality, smooth animations at scale.
  • Expressive motion: Bold, vivid motion with stable aesthetics and natural transitions.
  • Flexible resolution: 480p, 720p (default), 1080p, or 4k to match your needs.
  • Duration control: 4–15 second clips with fine-grained control.
  • Native audio: Optional synchronized audio for complete audiovisual output.

How to Use

  1. Upload your image (ensure clarity and proper framing).
  2. (Optional) Enter a prompt describing desired motion, mood, or camera movement.
  3. Select resolution and duration.
  4. (Optional) Set aspect_ratio to match your target platform.
  5. (Optional) Set a seed for consistent results.
  6. Click Run to generate your video.

Writing Effective Prompts

The input image sets the first frame — your prompt directs what happens from there. The clearer the motion and camera direction, the better the result.

1. Start from the frame

Describe the action that begins from your image: what the subject does, where it goes, how the camera moves. Don't re-describe what's already visible in the image — build on it.

The woman in the photo turns from the window and walks toward the camera; slow push-in, warm interior light.

2. Shot-by-shot timeline

For longer clips, break the motion into timed segments (1-second granularity), continuous, no gaps.

0-2s: She turns from the window, a faint smile forming. Camera holds. 2-5s: She walks toward the lens and stops mid-frame; slow push-in, shallow focus. 5-8s: She glances off-screen as light shifts from warm to cool. Handheld drift.

3. Consistency notes

Lock the look for the whole clip: camera style, lighting, palette, atmosphere, audio.

Camera language

Write these directly; the model understands them:

  • Shot size — extreme wide, wide, medium, medium close-up, close-up
  • Movement — push in, pull out, pan, track, follow, orbit, tilt up, handheld shake
  • Angle — low angle, overhead, eye-level, first-person
  • Techniques — one-shot / long take, dolly zoom, bullet time, speed ramp

For a niche term, add a plain-language gloss: "rack focus: the sharp foreground softens as the background comes into focus."

Referencing uploaded assets

When you attach images, videos, or audio, bind each one explicitly in the prompt by its upload order — @image1, @video1, @audio1 — and say what it's for. Don't rely on labels drawn inside the image itself.

  • "The knight in @image1 walks through the castle in @image2."
  • "Refer to @video1 for the camera movement only; keep its shot order."
  • "@image1 and @image2 are Character 1, voiced by @audio1."

When a reference is already accurate, just point to it — no need to re-describe it in detail.

Negative control

Positive descriptions work best, but you can suppress subtitles and audio:

  • "No subtitles."
  • "No BGM — ambient and action sounds only."
  • "No audio."

Weak vs. strong

prompt
weakmake it move
strongThe parked car in the image pulls out and drives down the wet street. 0-3s: headlights flick on, the car eases forward, reflections rippling on the asphalt. 3-6s: it accelerates past the camera, which pans to follow. Low angle, neon reflections, light rain, cinematic night mood. Engine and rain sounds, no music.

  • Audio generation: Enabling or disabling audio does not change the price.
  • Duration range: 4–15 seconds (continuous)

Notes

  • Works best with clear, well-lit images.
  • Match aspect ratios to your input image to avoid awkward crops.
  • Use Fast Spicy for iteration; switch to Seedance 2.0 Spicy when you need maximum quality.

How much does Seedance 2.0 Fast Image To Video Spicy cost per run?

Seedance 2.0 Fast Image To Video Spicy 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 Seedance 2.0 Fast Image To Video Spicy accept?

Key inputs: `prompt`, `image`, `aspect_ratio`, `resolution`, `duration`, `seed`. 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/bytedance/bytedance-seedance-2.0-fast-image-to-video-spicy.

How long does Seedance 2.0 Fast Image To Video Spicy take to generate?

Median end-to-end generation time on WaveSpeedAI is around 144 seconds per request, based on recent successful runs. Queue time varies with global demand; live status is visible in the prediction record.

Can I use Seedance 2.0 Fast Image To Video Spicy outputs commercially?

Commercial usage rights depend on the model's license, set by its provider (ByteDance). The license summary appears on the model card above; see WaveSpeedAI's Terms of Service for platform-level conditions.
