Stabilize Video

Reduce camera shake with correction, edge treatment, crop-impact feedback, and output-quality controls.

Single-pass deshake corrects whole-frame camera motion locally. It works best on hand jitter and walking footage; rolling-shutter wobble and motion blur remain in the source.

About Stabilize Video

Stabilize Video keeps the complete file workflow inside this browser tab. Your selected file, its name, contents, settings, and generated output are not sent to AntiUpload or a cloud conversion service. Ads and aggregate traffic analytics stay outside the processing boundary and receive no file object or working buffer.

AntiUpload's Video Stabilizer reduces camera shake in handheld footage — the kind of jitter that's normal in phone recordings, body-cam clips, or drone footage in wind. The tool runs FFmpeg's built-in `deshake` filter, which estimates per-frame motion between consecutive frames and applies an inverse transform to compensate. Three strength presets — subtle (8-pixel search range), moderate (16 px, the default, matches typical walking-pace handheld), and strong (32 px, for running / vehicle / point-of-view action) — let you match the correction intensity to how shaky the source is.

This is a single-pass whole-frame stabilizer, not a two-pass global motion tracker. It works best on hand jitter and walking footage. Rolling-shutter wobble, subject motion blur, and very large camera jumps cannot be reconstructed by moving the frame, so the page makes that boundary explicit instead of promising an AI-style repair.

Choose Minimum correction, Balanced, or Most stable based on the footage. Keep full frame reflects adjacent pixels into exposed edges; Clean edges removes a strength-dependent strip and scales the inner frame back to the original output dimensions. High, Balanced, and Smaller file quality presets control the H.264 size-detail tradeoff. The video is always re-encoded locally because every corrected frame must be redrawn.

How it works

  1. Drop your shaky videoAccepts MP4, MOV, WebM, MKV, AVI, M4V, FLV. The tool decodes the entire video, analyses motion frame-by-frame, applies the inverse transform, and re-encodes. Output is always MP4.
  2. Choose correction and edgesMinimum correction preserves more edge detail, Balanced suits typical handheld walking footage, and Most stable searches farther for larger motion. Keep full frame mirrors exposed edges; Clean edges crops and scales them away.
  3. Click Stabilize videoPick High, Balanced, or Smaller file output quality, then start. Processing time depends on clip length, resolution, correction level, browser, and device.
  4. Download the stabilized resultOutput preserves the source's resolution and aspect ratio. The edges may show subtle mirroring artifacts in the most-compensated frames — usually invisible at playback distance.

When to use Stabilize Video

Smoothing handheld phone footage before sharing
Phone gimbals are great but not everyone has one. Stabilize after the fact — moderate strength fixes typical walking-while-filming jitter without the artifacts of strong stabilization.
Fixing drone footage shot in wind
Even gimbal-mounted drones get jittery in 15+ knot wind. Strong strength compensates for the bigger motion swings. The mirror-edge fill keeps the framing tight.
Cleaning up GoPro / body-cam / action-cam clips
Action cameras are unstabilized by design — they record raw. Strong-strength stabilization restores watchability for the most chaotic shots without the cropping that hardware EIS (electronic image stabilization) imposes.
Stabilizing user-generated content for client videos
Agencies and creators receiving phone footage from clients can run it through the stabilizer before editing to give the final piece a more professional feel.
Stabilizing slow-motion clips that exposed micro-jitter
Slowing footage down with our Video Speed tool exposes shake that was invisible at normal playback. Stabilize after slowing for smooth slow-mo without the buy-a-gimbal step.

Frequently asked questions

Is it safe and private to stabilize video here?
Yes. Your video is processed entirely in your browser and is never uploaded to any server, so the file never leaves your device. You can confirm this by watching the Network tab or by going offline after the page loads. Input files are read from browser memory and the output is created locally for your download. AntiUpload does not send file bytes, names, sizes, page counts, contents, passwords, or generated outputs through analytics or advertising requests.
How to stabilize a shaky phone video for free online?
Drop your video into AntiUpload Video Stabilizer, choose a correction level, edge treatment, and output quality, then click Stabilize video. Processing stays in your browser and the output has no watermark.
How is this different from DaVinci Resolve's stabilizer?
Desktop editors can use multi-pass motion tracking and global motion models. AntiUpload uses FFmpeg deshake: a single-pass, whole-frame correction designed for lighter hand jitter and walking footage. It is a smaller local workflow, not a replacement for cinematic stabilization.
Will stabilization crop my video?
You choose. Keep full frame preserves the complete source and mirrors pixels into exposed edges. Clean edges removes a strength-dependent strip, then scales the inner image back to the original output dimensions. The configure summary shows the inner frame size before processing.
Why does my video look slightly weird at the edges?
That's the mirror-edge fill kicking in. When deshake pushes the frame heavily in one direction, the gap at the opposite edge is filled by mirroring the nearest content. On heavily-shaken source you may see this as a subtle ripple along the edges. Lower the strength to reduce visibility, or accept it as the trade-off vs cropping.
How long does stabilizing a 5-minute clip take?
Processing time depends on clip length, resolution, correction level, browser, and device. Stabilization decodes, analyzes, redraws, and re-encodes every frame, so long or high-resolution clips require more work.
Can I stabilize a 4K video?
Yes, subject to your browser and device memory. Higher-resolution video requires more frame memory and processing. If a long 4K clip exceeds your device capacity, trim it or create a smaller working copy first.
Does stabilization help with rolling-shutter wobble (jello effect)?
Slightly. Deshake corrects whole-frame motion, but rolling shutter is per-row distortion — different parts of the same frame are warped differently. There's no good in-browser fix for rolling shutter yet; the best mitigation is filming with a global-shutter camera or stabilising mechanically (gimbal) on the source side.
Does this work on Windows, Mac, iPhone, and Android?
Yes. It runs in any modern browser, so it works the same on Windows, Mac, Linux, iPhone, and Android with nothing to install. Stabilizing is processor-intensive, so larger clips will finish faster on a desktop than on a phone.
What's the maximum video file size I can stabilize?
There is no upload quota because nothing is uploaded, but the local workflow is limited by your browser and device memory. The preflight check uses device-aware limits; if a large file cannot run safely, trim it shorter or use a device with more available memory.
How do I remove camera shake from footage and keep the sound?
Drop the clip in, choose correction, edges, and quality, then click Stabilize video. The tool redraws the picture and re-encodes the audio to AAC in sync. The output is an MP4 rather than a lossless copy because stabilization must alter every video frame.
What video formats can I stabilize, and what do I get back?
You can stabilize MP4, MOV, WebM, MKV, AVI, M4V, and FLV files. Whatever you put in, the stabilized result comes back as an MP4, which plays everywhere. You stabilize one file at a time.
Why does the stabilized file look a little softer or larger than the original?
Because stabilizing isn't a stream copy — every frame has to be redrawn to cancel the shake, so the video is re-encoded. We use high-quality settings, but any re-encode is slightly lossy and the file size can shift depending on how much motion there was. If you want to keep size down afterward, run the result through our Video Compressor.
