Video Watermark Remover API Documentation

Video Watermark Remover API Documentation

Playground

Remove Kling and Seedance watermarks, logos, captions and text from videos while preserving quality; supports many formats and 10-minute files. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing.

Features

Remove Sora 2 watermarks, logos, captions, lower-thirds, and other unwanted on-screen text—while preserving the original look of your footage. Upload your video and get a clean result with minimal artifacts. If you need upscaling instead, try our AI Video Upscaler. No local setup required!

Why it looks great

• Temporal-aware inpainting: avoids flicker, keeps motion stable across frames.
• Clean plate reconstruction: rebuilds occluded details (textures, grain, lighting) beneath watermarks and captions.
• Smart text/logo targeting: robust to semi-transparent overlays, moving corner bugs, ticker bars, and burned-in subs.
• Edge & texture fidelity: preserves edges and fine detail without smearing or over-smoothing.
• Adaptive masking: optional user hints accelerate and improve results on complex, fast-moving overlays.

Limits and Performance

• Max clip length per job: up to 10 minutes
• Processing speed: approximately 5–20 seconds of wall time to process 1 second of video (varies by overlay complexity, resolution, and queue load)

Pricing

> Billing duration: Input media duration is rounded up to whole seconds. The minimum billed duration is 3 seconds; shorter inputs are billed as 3 seconds. Existing per-5-second rate tables remain unchanged.

Per-second billing with a 3-second minimum. The table below lists prices per 5 seconds for easy comparison.

Billing Rules

• Minimum charge: 3 seconds
• Per-second rate = (price per 5 seconds) ÷ 5
• Billed duration = video length in seconds (rounded up), with a 3-second minimum
• Total cost = billed duration × per-second rate

How to Use

2. Upload video: Upload the video you want to deal with.
3. Submit the job: Click the Run button.
4. Preview & download: review the cleaned clip and download it.

Notes

• Longer videos will require longer processing times.
• Please ensure your video upload format and URL are correct.
• The price displayed on the “Run” button is only an estimated reference; the final, accurate price will be based on the actual deduction.
