Video Cleaner API Documentation
Playground
Try it on WaveSpeedAI!Video Cleaner removes people, vehicles and other moving subjects from a video and rebuilds the background behind them, producing a clean plate of the same shot with the camera motion intact. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing.
Features
Video Cleaner removes people, pedestrians, vehicles, and other moving subjects from a video, then rebuilds the background behind them. It preserves the source video’s camera movement, static scene structure, lighting, framing, and duration while creating a cleaner plate for editing, compositing, or restoration workflows.
Why Choose This?
-
Moving-subject removal
Remove people, crowds, cars, bikes, and other dynamic elements from video footage. -
Background reconstruction
Rebuild the background where moving subjects were removed, including architecture, ground details, foliage, and static scene elements. -
Clean plate generation
Create cleaner footage for compositing, advertising, restoration, or post-production workflows. -
Prompt-guided cleanup
Usepromptto name extra objects that should also be removed. -
Multiple output resolutions
Choose480p,720p, or1080pwhile preserving the original aspect ratio. -
Seed support
Set a seed when reproducible cleanup results are needed.
Parameters
| Parameter | Required | Description |
|---|---|---|
| video | Yes | Input video URL or uploaded video. Up to 120 seconds is processed. |
| prompt | No | Optional comma-separated list of extra objects to remove, such as bicycle, dog, handlebars. |
| target_resolution | No | Output resolution: 480p, 720p, or 1080p. Default: 720p. Aspect ratio is preserved. |
| seed | No | Random seed for reproducible results. |
How to Use
- Upload a video — Provide the footage you want to clean.
- Add a prompt optional — Name extra objects that should also disappear.
- Choose target resolution — Select
480p,720p, or1080p. - Set seed optional — Use a fixed seed when reproducibility is needed.
- Submit — Generate the cleaned video output.
Pricing
Pricing is based on input video duration and selected target_resolution.
Billed duration is rounded up to the next whole second, with a minimum billed duration of 3 seconds and a maximum billed duration of 120 seconds.
| Output Resolution | Per 5s | Per second |
|---|---|---|
| 480p | $0.10 | $0.02 |
| 720p | $0.20 | $0.04 |
| 1080p | $0.50 | $0.10 |
Example Costs
| Input Duration | Billed Duration | 480p | 720p | 1080p |
|---|---|---|---|---|
| 1s | 3s | $0.06 | $0.12 | $0.30 |
| 3s | 3s | $0.06 | $0.12 | $0.30 |
| 5s | 5s | $0.10 | $0.20 | $0.50 |
| 10s | 10s | $0.20 | $0.40 | $1.00 |
| 60s | 60s | $1.20 | $2.40 | $6.00 |
| 120s | 120s | $2.40 | $4.80 | $12.00 |
prompt and seed do not add separate charges.
Best Use Cases
- Clean plate creation — Remove moving subjects and generate a cleaner background plate.
- People and crowd removal — Remove pedestrians, crowds, or foreground people from footage.
- Vehicle removal — Remove cars, bikes, scooters, or other moving vehicles.
- Advertising workflows — Create clean plates for product compositing or campaign production.
- Post-production cleanup — Remove unwanted moving elements from short clips.
- Scene preparation — Prepare cleaner footage before relighting, colorization, restoration, or compositing.
Pro Tips
- Use footage where the background is visible around the moving subject.
- Large foreground subjects that cover most of the frame may leave too little background to reconstruct.
- Use
promptwhen a specific object remains after the first cleanup pass. - Name objects clearly, such as
bicycle,dog,car, orperson in the background. - Use clean source footage with stable motion when possible.
- Keep the same
seedwhen you want to reproduce a result. - For advertising plates, clean the clip first, then composite the product onto the result.
Limits and Performance
- Maximum processed video length per job:
120seconds. - Input beyond
120seconds is not processed or billed. - Processing time can vary by resolution and video content.
- Higher output resolutions generally take longer to process.
Notes
videois required.target_resolutiondefaults to720p.- Aspect ratio is preserved.
- Billed duration is rounded up and clamped to
3–120seconds. - Very short videos are billed as
3seconds. - This endpoint is designed to remove moving subjects and rebuild visible background regions. It is not intended for changing the scene content or extending the video.
Related Models
- Video Restorer — Restore damaged footage by reducing compression artifacts or improving soft-focus video.
- Video Colorizer — Add or restore color in video footage for restoration and creative enhancement workflows.
- Video Cleaner — Clean up video noise, artifacts, and visual imperfections for clearer output.
- Video Relighter — Adjust or improve video lighting while preserving the original scene and motion.
