Super Video Speed Hayamaru

Video/audio speed by slider or keys. Hold to boost, A-B repeat, frame step, per-site off, YouTube playlist exclusion. No network.

Set a playback speed once, and keep it — with per-playlist exceptions. Control video and audio playback speed with a slider, presets, an on-video panel, or the keyboard. ■ Three promises - Completely free: every feature, no paid plan, no purchases - No login, no sign-up: install it and start using it - Made in Japan: developed in Japan by a Japanese company ■ What makes this different: per-playlist exclusion "I watch everything at 1.8x, but I want music playlists at normal speed." Doing that video by video is tedious. Open the playlist, click the toolbar icon, tick one checkbox. From then on, every video in that playlist plays at the speed you chose (1.00x by default), automatically. You register it once. Excluded playlists are listed in the popup, and you can give each one your own name. Rename or remove them with a single click. ■ How the speed is decided (top wins) 1. This video only 2. Excluded playlist 3. This playlist 4. This site 5. Global default Different speeds are remembered per site, per playlist and per video. ■ Changing the speed - Slider from 0.25x to 16x, on a logarithmic scale - Presets for the rates you use most - Fine +/- buttons, with a configurable step (0.25 by default) - A "favourite rate" you can toggle against 1.0x with one key - The toolbar badge always shows the current rate ■ Playback controls - Skip back and forward (10 seconds by default, configurable) - Frame stepping, with a configurable frame rate (30fps by default) - A-B repeat: first press sets A, second sets B, third clears - Picture-in-picture - Save the current frame as an image ■ On-video panel Hover over the video to show a small panel: play, rate, skip, frame step and repeat, right where you are looking. Opacity is adjustable, and you can hide it entirely. ■ Press and hold to speed up Hold the mouse button down on the video and it speeds up; release and it goes back. The rate and the hold threshold are configurable. It does not trigger on the progress bar or on buttons. ■ Keyboard — every key can be reassigned D faster Z back 10s Q A-B repeat S slower X forward 10s E picture-in-picture R reset to 1.0x , frame back Y save current frame G favourite rate . frame forward V show/hide the panel Keys are ignored while you are typing in a text field and while an IME composition is active, so you will never change the speed by accident. To rebind, just press the key you want; duplicates are flagged. ■ Audio-only pages too Radio, podcasts and language material that use <audio> work the same way. You can also choose whether pitch is preserved. ■ Picture and sound adjustments - Brightness, contrast, saturation - Grayscale, colour inversion - Vertical and horizontal flip - Volume boost up to 5x, for quiet sources These are remembered per site. ■ Per-site control - "Do not use on this site" for pages whose shortcuts would clash - Excluded sites are listed and can be restored at any time ■ On-screen display The rate appears on screen when it changes, including in fullscreen. Corner, text size and duration are configurable, and it can be turned off. ■ Other - 0.25x to 16x (browsers mute audio above 4x) - Works in embedded iframes - Export your settings to a file and move them to another computer - Follows your light / dark theme - Interface in English or Japanese, switchable at any time - Reset everything to defaults at any time ■ Built to be trustworthy - Made in Japan - Contains no networking code at all - Nothing is collected, sent or shared — not the pages you visit, not the videos you play - Settings are stored only on your own computer, and never synced - No ads, no purchases, no account - No third-party libraries - Requests only storage (to save your settings) and activeTab (to read the URL when you click the icon) - The code is MIT licensed, and Chrome extensions ship as readable files, so every claim above can be checked in the package itself ■ Known limits, stated plainly - Above 4x, browsers mute the audio (the video still plays) - The volume boost does not work on every site - Protected video (streaming services) cannot be saved as a frame image - Per-playlist exclusion needs a site that puts the playlist in the URL - Browser-internal pages and the Chrome Web Store are out of reach - Picture-in-picture must be started by a user action, by browser rule
