Video Humanizer forShort Clips.

Short-video mode runs locally in the browser. Upload a clip, inspect the preflight checks, and export an MP4 without sending the file to a backend.

Pipeline pillars

What runs under the hood

Full Codec Re-Encode

The clip is fully re-encoded with H.264 (libx264), so the source model's encoder fingerprint, GOP layout and quantization profile are replaced by a standard playback-grade stream.

Motion-Safe Micro-Transforms

A subtle horizontal flip, micro-zoom, slight rotation and re-centered crop shift the framing just enough to break exact-match and frame-hash fingerprints — with no visible change to the clip.

Container & Metadata Rebuild

The output container is rebuilt with plausible recording-device tags instead of the AI tool's identifying metadata.

Motion-Safe Color Grading

Optional soft, fade, warm, cool and contrast passes apply gentle, intensity-controlled brightness, contrast and color-balance shifts that read like natural in-camera processing.

Chroma & Aspect Normalization

Output is normalized to 4:2:0 chroma (yuv420p) with a clean aspect ratio — matching how phones and consumer cameras store footage. Additional refinement passes are applied internally.

Browser-Only Processing

Runs entirely on your device with ffmpeg.wasm in a Web Worker. Your video never reaches a server.

How it runs

Three steps, all local

01

Drop video

Drag any AI-generated MP4, MOV or WebM clip. Sources up to 4K, clips up to 30 seconds.

02

Local processing

ffmpeg.wasm runs the transform graph and a full re-encode in a Web Worker. Typical: 1–2× clip duration on a modern laptop.

03

Authentic export

Download a re-encoded MP4 with a standard codec profile and rebuilt container metadata.

FAQ

Common questions

Which AI video models does this handle?

Sora, Runway Gen-3, Pika, Kling, Luma — anything that exports a standard MP4 / MOV / WebM. The pipeline is model-agnostic: it decodes the clip and re-encodes it with the transform graph applied.

Does it work on iPhone HEVC clips?

HEVC sometimes fails inside browser decoders. If a clip refuses to load, transcode to H.264 MP4 first — any free converter works.

What's the maximum clip length?

Up to 30 seconds. Sources up to 4K are accepted and downscaled to a 1080p-class export for a stable in-browser encode. Longer clips are on the roadmap as the encoder is optimized.

Is the audio touched?

Audio is preserved when present — it's re-encoded to AAC (128 kbps), while the geometry and color transforms only affect the video stream.
