How does browser-based video stabilization work?

This tool uses FFmpeg WebAssembly’s deshake filter. For each frame, it searches the previous frame for the best translation match (within a configurable rx/ry radius — larger radius = stronger stabilization) and shifts the frame to compensate for camera motion. All processing happens locally in your browser — no files are uploaded.

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

Smoothing controls how far deshake searches between frames. Light (rx/ry=16) removes micro-shakes while preserving intentional movement. Medium (32) balances stability and natural motion — best for most handheld footage. Strong (64) 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?

Every frame runs a motion search against its predecessor within the configured radius — higher radius means more work per frame. Expect roughly 1-2× the video duration for processing with Medium smoothing, more with Strong, depending on resolution and device.

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 — we use edge=mirror to reflect pixels at the borders and avoid black padding. For best results, shoot with slightly wider framing than you need.

Comment utiliser — Stabilize Shaky Video Online Free — No Watermark

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.

Process the footage

Click "Stabilize Video". FFmpeg runs the deshake filter frame-by-frame, shifting each frame to compensate for camera shake. Expect roughly 1-2× video duration depending on resolution and smoothing strength.

Preview and download

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

Questions Fréquentes

How does browser-based stabilization work?

It uses FFmpeg WebAssembly’s deshake filter. For each frame, deshake searches the previous frame for the best translation match within a configurable radius, then shifts the frame to compensate. 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 (rx/ry=32) works best for most handheld footage. Use Light (16) for action/sports where you want to preserve some camera movement. Use Strong (64) for very shaky clips.

Why is stabilization slower than trimming?

Deshake does a motion search on every frame — more expensive than just copying frames. Expect roughly 1-2× the video duration for Medium, more for Strong.

Will it crop my video?

Slight edges can be affected as frames shift to compensate for shake. We set edge=mirror so borders are reflected rather than padded black. Shoot slightly wider than needed for best results.
