Video Stabilizer
Remove jitter and shakiness from handheld or camera footage. Motion analysis detects inter-frame movement and applies trajectory smoothing to produce fluid, stable video. Works entirely in your browser — nothing is uploaded.

Motion analysis and trajectory smoothing remove shake from handheld footage
How it works
Upload your video
Drop an MP4, WebM, or MOV clip. The motion analysis runs at 1/4 resolution for speed.
Analyze & smooth
Inter-frame translation is detected using block matching. A moving-average smoother (adjustable strength) corrects the trajectory.
Download stabilized clip
Frames are re-rendered with corrections applied and slight cropping to hide shifted borders. Export as WebM.
Common use cases
Action camera footage
Stabilizing shaky GoPro or phone footage from sports and outdoor activities.
Handheld documentary
Smoothing handheld interview footage for a more professional look.
Travel videos
Fixing camera shake from walking, running, or vehicle movement.
Drone footage
Correcting remaining shake in drone clips after in-camera stabilization.
Event coverage
Stabilizing hand-held wedding, concert, or sports event recordings.
Social media clips
Quick stabilization pass before posting to TikTok or Instagram Reels.
Frequently asked questions
How does browser-based stabilization work?
Optical flow analysis detects movement between each pair of frames. A moving-average trajectory smoother then corrects the camera path — all without sending any data to a server.
What formats are supported?
MP4, WebM, and MOV are accepted as input. The stabilized output is exported as WebM (VP9).
Does it change the aspect ratio or crop?
Stabilization may add a slight crop to allow for motion correction — shifted frame borders are hidden so the output stays clean.
How long does processing take?
Depends on clip length and resolution. A typical 30-second clip takes roughly 1–3 minutes on a modern device.
Will the output frame count match the input?
Yes. Stabilization preserves the exact frame count — no extra or missing frames are introduced.
Why it's different
Browser-based video stabilization — motion analysis and trajectory smoothing run entirely on your device. No upload, no server, completely private.
100% Private
Everything runs on your device using in-browser AI. Nothing is transmitted to any server — not the file, not metadata, not filenames.
True Alpha Channel
We export straight (non-premultiplied) alpha so transparent PNGs open with a real checkerboard in Photoshop and Figma — no black halos.
Free Forever
No paywall, no watermark, no premium tier. The full-quality AI is free, supported by non-intrusive ads.
Works Offline
Once loaded, the app and AI models cache locally. Process files without an internet connection. Installable as a desktop or mobile app.
