About this app

Stabilize shaky video and compress video to a fraction of its size, keeping the picture crisp. Aisu is a video stabilizer that turns handheld footage steady, and a video compressor that reduces video size so long clips finally send on WhatsApp, TikTok, Instagram, Discord, Messenger or email — no more "file too large". New: Auto quality picks the right level for every video.



🎬 Why Aisu Video Compressor?

Phone videos come out shaky and too big to share or store. Aisu steadies them, shrinks them while keeping detail sharp, and covers faces you'd rather not show — on your device, offline and private. No watermark; premium is a one-time purchase, not a subscription.



🎥 Stabilize shaky video

• 📈 Motion analysis first — Aisu tracks the motion on a temporary copy, charts shakiness, scene cuts and peak shake, and proposes a plan estimating "X% less shake".

• 🎯 Tracks the camera, not the scene — flowing water, a crowd or a child crawling through the frame don't fool it: still shots stay still, real scene changes stay cuts.

• ⚙️ Gentle, Balanced or Strong — you choose how much frame to trade for steadiness. Dynamic zoom lets the crop move and absorb more shake.

• 🔧 Per-segment control — Steady, Mild, Very shaky and Extreme stretches; skip any segment or give it its own crop.

• 📐 Rolling-shutter correction straightens the "jello" wobble phone sensors add; Aisu tells you upfront when a clip is already steady or its wobble can't be fully removed.

• 🏷️ Keep the original quality, or stabilize and compress in one pass; results carry a Stabilized badge.



🙈 Blur faces before you share

• 🔍 Finds every face automatically, on your phone — nothing is uploaded.

• 👥 Cover everyone, pick people one by one, or blur the background and keep the faces.

• 🎨 Blur, Mosaic, Solid or Emoji, oval or rectangle, with adjustable strength and size.

• ✅ Coverage check shows where a face was lost for a moment, so you can scrub through before sharing. Your original stays untouched.

• 📤 Share a video to Aisu from any app and pick Blur faces.



✨ Compress video, reduce size

• 🪄 Auto quality — Share, Balance or Archive, tuned to each video — 4K, 1080p or smaller — with honest size estimates.

• ⚖️ Compare before you start — short samples of your video with measured sizes, side by side or before/after.

• 🎯 One-tap Fit to Size — WhatsApp 16 MB, Discord 10 MB, Instagram DM 25 MB, Email 25 MB, TikTok 72 MB, Messenger 100 MB or a custom size; a whole-video analysis pass lands on target, not over.

• 📤 Share into Aisu as Compress, Stabilize or Blur faces; when it finishes, the share sheet opens.

• 🗑️ Free Up Space — see every version of a video, keep the one you want and trash the rest, recoverable for 30 days. Or let Aisu offer to trash the original after each compression.

• 📦 Batch compressor — queue as many videos as your device handles, run several at once, pause, resume or reorder anytime; the durable queue survives restarts.

• 🎛️ Fine control — resolution, bitrate, fps cap and sharpness that restores detail lost to downscaling, per video or as a preset.

• 🧩 H.264 (AVC) and H.265 (HEVC) presets — HEVC roughly halves file size at the same quality.

• 🕓 History and a space-saved dashboard track what you've reclaimed.

• 📁 MP4, MOV and other common formats; save to the app folder, a folder you pick, or the original's folder.

• 🌍 In 13 languages.

• 🔒 100% private and offline — nothing is ever uploaded.



👤 Perfect for

Creators, vloggers, parents, students — steadying a shot filmed without a gimbal, posting to TikTok or Instagram, emailing a long clip, sharing a video of the kids without showing every face, or clearing space.
