Stabilize a Shaky Video
Pick a video and a strength — handheld camera shake is smoothed away in your browser, nothing is uploaded.
Smooth out camera shake
Pick a shaky handheld clip, choose how much shake to compensate and what to do with the frame edges, and get the same clip back with the wobble smoothed away. Everything runs with ffmpeg inside your browser tab — nothing is uploaded, and the tool is free.
The stabilizer (ffmpeg's motion-detection deshake filter) measures the
dominant frame-to-frame movement and shifts each frame to cancel it, so
handheld jitter is smoothed while intentional pans are kept. Because every
frame is rewritten, the picture is re-encoded to H.264 (-crf 20, visually
near-transparent). The audio is left untouched (stream-copied) whenever the
container can hold H.264/AAC — mp4, mov, m4v and mkv keep their container;
other inputs (e.g. webm) are converted to MP4 and the audio re-encoded to AAC.
Strength and edge handling
- Strength (1–100) sets the motion search radius — how big a shake the
stabilizer can detect and cancel. It steps through the four radii the
deshake filter accepts: 1–25 → 16 px, 26–50 → 32 px, 51–75 → 48 px,
76–100 → 64 px.
- Subtle (10–20) — minor jitter, tripod bumps, breathing wobble.
- Normal (25–40) — typical handheld phone footage. The default of 25 matches ffmpeg's own deshake default.
- Strong (50–100) — walking shots and action-cam shake; very high values can wobble on intentional camera moves, so raise it gradually.
- Edges — shifting a frame to cancel shake exposes a band at its edges;
this picks what fills it:
- Mirror (default) — reflects the picture into the band. No zoom, full resolution, usually invisible on busy footage.
- Crop & zoom — zooms in slightly (about 3–10 %, growing with strength) and center-crops so the moving edges fall outside the visible frame — what most stabilizers do by default. Costs a little field of view.
- Blank — black bands, useful to see how much correction is applied.
- Original — keeps the unstabilized source pixels at the edges.
Worked example
You have walk.mp4, a 1080p clip filmed while walking, and the horizon bounces
with every step. Load it, set Strength to 60 and Edges to Crop &
zoom. You get walk-stabilized.mp4 — the same footage with the bounce
smoothed and a slight (~7 %) zoom hiding the shifting edges. If the result
still jumps, raise the strength; if straight lines near the frame edge look
smeared on a mirror run, switch to Crop & zoom. The page URL
/tools/video-stabilize/?borders=crop&strength=60 deep-links to the same
pre-filled settings.
Notes and limits
- This is single-pass motion-compensation stabilization — great for mild to moderate handheld shake. Severe GoPro-style shake or rolling-shutter "jello" needs a two-pass or gyro-based stabilizer, which no in-browser tool provides.
- One setting applies to the whole clip; there is no per-scene control and no timeline selection — trim first with a cut tool if you only need a segment.
- Crop & zoom trades a little field of view for clean edges; on very small videos (under ~300 px) strong shake can still leave slight edge artifacts.
- The picture is re-encoded, so the output is not byte-for-byte identical to
the source.
-crf 20keeps the loss visually negligible. - Input and output are each capped at 25 MB (the file is processed in your browser's memory).
FAQ
Is my video uploaded to a server?
No — ffmpeg runs inside your browser tab, so the file never leaves your device. Nothing is uploaded and nothing is stored.
What strength should I use?
Start at the default 25 for ordinary handheld footage. Use 10–20 for minor jitter, 30–40 for a normal phone walk-and-talk, and 50 + only for genuinely rough footage (running, action cams). Too high a strength can start "correcting" intentional pans, which shows up as a slow wobble — if you see that, lower it.
Why do the edges of my stabilized video look odd?
To cancel shake the stabilizer shifts each frame, which exposes a thin band at the frame edges. Mirror (the default) fills it by reflecting the picture — usually invisible, but straight lines right at the edge can look smeared. Switch Edges to Crop & zoom to hide the band completely at the cost of a slight zoom, or Blank if you'd rather see black bands.
Does Crop & zoom change my video's resolution?
Only marginally — the picture is scaled up by roughly 3–10 % (more at higher strengths), then center-cropped back to within a couple of pixels of the original width and height (dimensions are kept even for H.264). You lose a little field of view at the edges, not output size.
Can it fix very shaky GoPro or running footage?
It will help, but this is a single-pass motion-compensation filter — it works best on mild to moderate shake. Severe action-cam shake and rolling-shutter "jello" need two-pass (analyze-then-transform) or gyro-data stabilization, which is desktop-software territory. For those clips, run Strength 60–100 with Crop & zoom and expect an improvement, not a gimbal.
Which formats can I use, and how big can the file be?
Anything ffmpeg can read — mp4, mov, m4v, mkv and webm are the common cases. mp4/mov/m4v/mkv keep their container; other inputs (e.g. webm) come out as MP4. The input and output are each capped at 25 MB.
