Body Shake Effect

Requirements

Number of Images

  • Mandatory
  • Only one image upload supported

Number of People

  • Supports single-person photos in realistic or anime style

Image Requirements

  • When the person is fully visible from above the thighs, the effect is better

Prompt

  • Mandatory
  • Format should remain unchanged as much as possible
  • If custom requirements exist, modify the prompt without altering the structure and majority of the content

Effect Boundaries

  • Close-up portraits may result in distorted facial proportions or reduced generation quality
  • When the subject's hands are raised or positioned behind the body, hand blurring or structural issues may occur
  • Multi-subject images may lead to misaligned characters, missing subjects, or mesh clipping
  • If only the lower legs (with shoes) are visible and the upper body is missing, the subject may not be able to perform turning movements
  • Back-facing inputs may fail to generate a front-facing rotation

Best Practices

  1. Use clear, front-facing photos
  2. Ensure subject is fully visible from above the thighs
  3. Avoid close-up portraits
  4. Keep hands visible and in natural positions
  5. Use single-person photos only

Body Shake API — Quick start

Grab a WaveSpeedAI API key, then call POST https://api.wavespeed.ai/api/v3/video-effects/body-shake with your input as JSON. The endpoint returns a prediction id. Start polling the result endpoint around every 2 seconds, increase the interval for long-running tasks, and stop on any terminal status. On completed, read output values from data.outputs. Examples for Body Shake below.

HTTP example
set -euo pipefail

REQUEST_BODY=$(cat <<'JSON'

Body Shake API — Frequently asked questions

What is the Body Shake API?

Body Shake is a Video Effects model for AI inference, exposed as a REST API on WaveSpeedAI. Turn photos into realistic body-shaking dance videos with natural motion and expressive emotion. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing. You can call it programmatically or try it from the playground above.

How do I call the Body Shake 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. Submission returns a prediction ID. Poll the result endpoint starting around every 2 seconds, increase the interval for long-running tasks, and stop on any terminal status. The playground generates production-oriented Python, JavaScript, and cURL examples with timeouts, transient-error handling, and safe GET retries. Full request/response shape is documented at https://wavespeed.ai/docs/docs-api/video-effects/video-effects-body-shake.

How much does Body Shake cost per run?

Body Shake starts at $0.20 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 Body Shake accept?

Key inputs: `image`. 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/video-effects/video-effects-body-shake.

How long does Body Shake take to generate?

Median end-to-end generation time on WaveSpeedAI is around 41 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 Body Shake outputs commercially?

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