VideoAce — Universal Video Controller, Speed, Boost, Screenshot

Control any HTML5 video. Speed 0.07x–16x, frame-step, A-B loop, screenshot, PiP, bookmarks, boss key. 100% local.

Take control of any HTML5 video on any website. VideoAce gives you a single, minimal floating HUD that appears on every video — YouTube, Coursera, Twitch, Vimeo, MOOCs, your local mp4 file, anywhere. Eleven professional features. Zero clutter on sites that don't need it. 100% local. ═══════════════════════════════════════════════════════════════ THE 11 FEATURES ⚡ SPEED — 0.07× to 16× in fine 0.1 steps. Eight preset speeds one tap away (0.25, 0.5, 0.75, 1, 1.25, 1.5, 2, 3, 4, 8). Click the speed badge to cycle. Press 0/1/2/3/4 for direct preset jumps. 📷 SCREENSHOT — capture the current frame as PNG. Saved straight to your Downloads. (DRM-protected players block this — VideoAce gracefully tells you instead of failing silently.) 🎞️ FRAME STEP — paused-video frame-by-frame in both directions. Useful for screenshots of specific moments, tutorials, or inspecting motion. 🔁 A-B LOOP — set point A, set point B, video loops between them automatically. Indispensable for music practice, language immersion, or re-watching tricky lecture moments. 🪟 PICTURE-IN-PICTURE — float the video on top of every other window. One key (P). 🥷 BOSS KEY — instantly hides every video behind a plain "Loading…" page. Pauses them so audio stops too. Press again to come back. ⏭️ SKIP 10 SECONDS — the universal ad-skip shortcut. Built in. ⭐ BOOKMARKS — flag interesting moments. Recall them with a keystroke. 🎛️ PER-SITE MEMORY — your preferred playback speed sticks per website. Watch lectures at 1.5× and short clips at normal, automatically. 🎨 FLOATING HUD — a small, draggable, scale-able heads-up display. Shadow-DOM isolated so the host site's CSS can't break it. Auto-hides on toggle (V). Only ONE HUD ever visible — the active video's — even on sites with multiple <video> elements. ⌨️ FULLY REBINDABLE — every keyboard shortcut can be customised in the options page. Including modifiers. ═══════════════════════════════════════════════════════════════ KEYBOARD SHORTCUTS S / D Slower / faster (0.1 step) R Reset to 1× G Custom speed prompt 0–4 Direct preset (0.5× / 1× / 2× / 3× / 4×) , / .

No analytics, no telemetry, no account, no server. Verify in chrome://extensions → Inspect — zero fetch() calls in our code. 🎯 Works EVERYWHERE there's a <video> tag. We detect SPA navigation, dynamic player swaps (YouTube quality change), and even videos inside same-origin iframes (Coursera, Khan Academy). ⚡ Zero performance penalty. The HUD is plain CSS in a shadow root. Idle CPU: 0%. 🎨 Modern UI. Cyan-purple gradient. Drag the HUD anywhere — its position is remembered per site. ═══════════════════════════════════════════════════════════════ QUICK START 1. Install 2. Open any video site (YouTube, Coursera, Twitch, anything with a <video> tag) 3. The HUD appears on the player. Press V to hide / show. 4. Speed up with D, slow down with S. Try 0/1/2/3/4 for instant preset speeds. ═══════════════════════════════════════════════════════════════ LANGUAGES English · Türkçe · Deutsch (auto-selected by browser locale) ═══════════════════════════════════════════════════════════════ PART OF AION EXTENSIONS VideoAce is part of the AION Extensions family — 22 premium browser tools, all privacy-first, ad-free, account-free: • PDFTouch — edit, sign, OCR, merge PDFs entirely in-browser • CaptureKit — screenshots + screen recorder + GIF export • LinguaLens — learn languages from Netflix / YouTube subtitles • AION Ad Blocker — EasyList + AdGuard, 300k+ rules • ClipFlow — P2P clipboard between desktop & phone • NoiseSquelch — AI mic noise suppression • …and 16 more at aionextensions.pages.dev
