How does browser-based video stabilization work?

This tool uses FFmpeg WebAssembly with the vidstab library. It performs two-pass processing: Pass 1 analyzes camera motion and detects shake patterns, Pass 2 applies compensating transforms to produce smooth, stable footage. All processing happens locally in your browser — no files are uploaded.

What is the difference between light, medium, and strong smoothing?

Smoothing controls how aggressively camera motion is corrected. Light (10) preserves intentional camera movement while removing micro-shakes. Medium (20) balances stability and natural motion — best for most handheld footage. Strong (40) maximizes stability but may crop more of the frame and look overly smooth for action shots.

Why does stabilization take longer than other video tools?

Video stabilization requires two full passes through the video. Pass 1 analyzes every frame to detect motion vectors (how the camera moved). Pass 2 re-renders each frame with compensating transforms. This is computationally intensive — expect 2-5x the video duration for processing, depending on resolution and device performance.

Will stabilization crop my video?

Slight cropping can occur because the stabilizer shifts frames to compensate for shake. The stronger the smoothing and the shakier the footage, the more cropping may occur. The tool applies an unsharp filter to maintain edge quality. For best results, shoot with slightly wider framing than you need.

Cómo usar — Video Stabilizer

Upload your shaky video

Drag and drop any video file (MP4, WebM, MOV). The video loads locally — nothing is uploaded to any server.

Choose smoothing strength

Light for subtle correction (keeps natural camera movement), Medium for balanced results (best for most footage), or Strong for maximum stability.

Two-pass processing

Click "Stabilize Video". Pass 1 analyzes camera motion frame-by-frame. Pass 2 applies compensating transforms. This takes longer than simple edits — expect 2-5x video duration.

Preview and download

Preview the stabilized result, compare with the original, and download your smooth video. No watermark, no quality loss beyond stabilization cropping.

Preguntas Frecuentes

How does browser-based stabilization work?

It uses FFmpeg WebAssembly with vidstab. Pass 1 detects camera shake patterns, Pass 2 applies compensating transforms. All processing is local — no server upload.

Is this really free with no watermark?

Yes. Processing runs in your browser using WebAssembly, so there are no server costs. No watermark, no signup, no file limits beyond browser memory.

What smoothing strength should I use?

Medium (20) works best for most handheld footage. Use Light (10) for action/sports where you want to preserve some camera movement. Use Strong (40) for very shaky clips or tripod-like results.

Why is stabilization slower than trimming?

Stabilization requires two full passes — motion analysis + transform application. It's computationally intensive. Expect 2-5x the video duration for processing.

Will it crop my video?

Slight cropping may occur as frames are shifted to compensate for shake. Stronger smoothing + shakier footage = more cropping. Shoot slightly wider than needed for best results.
