Upload a shaky clip — we run a two-pass ffmpeg vid.stab workflow (optical-flow detect + rewarp) and return a gimbal-smooth MP4. Best results on handheld walking footage, drone clips, and bodycams. Heavy job (~2–3× realtime) so cost scales with duration.

MP4, MOV, WebM up to 200MB — shorter clips finish faster

Subtle ~1% crop, Medium ~2%, Maximum ~4%. More strength = more crop but smoother output.
Zoom-to-fill keeps output resolution identical to input.

Footage types this fixes

Handheld walking clips

Vlogs, travel B-roll, city walks — vid.stab smooths the rolling footfall bounce out of the frame.

Drone & gimbal footage

Cleans up prop vibration and wind-induced micro-shake. Medium strength is the sweet spot.

Bodycam & action-cam

GoPro, Insta360, Osmo Action — run through Maximum strength for the jitter-free cut.

How vid.stab works

Two passes. Pass one runs vidstabdetect — optical-flow analysis that tracks hundreds of visual features per frame and writes out a .trf motion file. Pass two runs vidstabtransform, which uses that motion file to build a smooth virtual camera path and rewarps each frame to match it. The result is what a physical gimbal would have given you on the original shoot.

vs. DaVinci Resolve / Premiere / iMovie

Resolve has a great stabilizer, but it is behind a 1.2GB install and a project timeline. Premiere costs $23/mo. iMovie's Smooth Clip is lightweight but naive. vid.stab — which is what ffmpeg uses under the hood here — is the same library OpenShot and Avidemux ship. For a one-off stabilization, a browser upload is 10× faster than opening a project.

When NOT to run this

  • Footage shot on a modern gimbal (DJI RS, Ronin) — it is already stabilized; a second pass over-corrects and introduces wobble.
  • Deliberate camera moves (whip pans, dolly shots) — vid.stab will fight them and remove the intended motion.
  • Extreme rolling-shutter jello (cheap phone at high shutter speed) — vid.stab cannot unbend CMOS artifacts. Re-shoot with a lower shutter angle if possible.

AI Video Stabilizer — FAQ

Upload a shaky handheld clip and we smooth it out using ffmpeg vid.stab — a two-pass optical-flow stabilizer that detects motion in pass 1 and rewarps frames in pass 2. The result looks gimbal-stable, even if you shot it walking on uneven ground.

Yes. Stabilization is the heaviest local ffmpeg flow on Free.ai (two passes + re-encode at ~0.4× realtime) so the rate is 80 tokens per second of source with a 500-token floor. A 30-second clip costs 2,400 tokens — inside the daily pool for signed-in users on a normal day.

vid.stab is the same motion-estimation library behind OpenShot, Avidemux, and many pro workflows. It tracks hundreds of features per frame and builds a smooth camera path, whereas naive deshake filters only consider pixel differences. The output is noticeably smoother — especially on walking footage.

Subtle, Medium, and Maximum. Subtle uses a small smoothing window (10 frames) and minimal crop — ideal for already-decent footage you want to polish. Medium (20-frame window, 2% zoom) is the default. Maximum (40-frame window, 4% zoom) is for drunk-cam-level shake where you accept a larger crop to get a stable picture.

Stabilization has to zoom in slightly to hide the edges that fall outside the stabilized frame. Subtle loses ~1%, Medium ~2%, Maximum ~4%. Pick the Zoom-to-Fill crop mode if you want the output at the same resolution as the input (the edges are implicitly filled by zoom).

MP4, MOV, WebM, MKV, AVI — any ffmpeg-decodable container. Output is always H.264 MP4 for maximum compatibility. Input cap is 200MB; shorter clips stabilize faster and cost less.

Roughly 2–3× realtime. A 30-second clip finishes in about 60–90 seconds. Longer clips may hit our 8-minute ffmpeg timeout — if you have a 5-minute shaky vlog, trim it into 60-second chunks first.

Yes — drone footage is exactly the use case vid.stab shines at. Medium strength removes gimbal jitter and prop vibration without chewing into the frame. Do not stabilize footage that already has active gimbal correction; you will double-correct and introduce wobble.

Yes. Audio is passed through unchanged (stream-copy) so there is no re-encode artifact or sync drift. Only the video stream is rewarped.

Resolve is a full NLE with a great stabilizer behind a 1GB install. For a one-off clean-up, a browser upload is 10× faster. If you are editing a multi-track project with color grading, use Resolve; if you just want one clip stabilized, use this.

No. Input files are deleted the moment stabilization finishes. The stabilized output is kept on our CDN for 24 hours (7 days for signed-in users with credits).

Yes. POST multipart to /v1/video/stabilize/ with `file`, `strength` (subtle / medium / max), `crop` (auto / no-crop / zoom). Pre-flight: GET /v1/video/stabilize-quote/?duration=SECS. Full snippets at /api/.
