Playback Pro - Video Speed, Audio Boost & Loop

Accelerate HTML video & audio (0.07x–16x), boost sound up to 600%, step frames, A-B loop, with sleek glass HUD and custom shortcuts.

Speed up, slow down, boost volume, step frames, and loop HTML5 video with shortcuts. HTML5 video provides native playback controls, but most implemented players either hide or limit this functionality. Playback Pro fixes that, plus adds 600% sound amplification, frame navigation, and repeat looping... It helps you optimize your video viewing by allowing you to make quick playback speed adjustments, amplify quiet audio, step frame-by- frame, and loop scenes. Once installed, simply navigate to any page with HTML5 video, and you'll see an elegant floating control pill over the video player. - Works on any site with HTML5 media: YouTube, Netflix, Coursera, local files, etc. - Fine-grained speed controls: 0.07x to 16x in configurable increments with pitch preservation. - 600% Web Audio sound booster: cleanly amplify quiet dialogue and muffled audio tracks. - Precision frame navigation: step forward or backward frame-by-frame (~0.04s precision). - A-B repeat looping: set start and end points for seamless study and practice. - Sleek floating HUD: draggable, click to reset, and auto-hides when idle. - Fully customizable shortcuts: interactive keycap recorder to rebind any key. Hover over the on-screen pill to reveal the controls, or use your keyboard: - S - decrease playback speed (-0.05x) - D - increase playback speed (+0.05x) - R - reset playback speed (1.0x) - G - toggle preferred speed (2.0x) - Z - rewind video by 10 seconds - X - advance video by 10 seconds - V - show / hide controller HUD - [ - step 1 frame backward (~0.04s) - ] - step 1 frame forward (~0.04s) - Shift + A - set loop start (Point A) - Shift + B - set loop end (Point B) - Shift + C - clear active loop - B - boost volume gain (+25%) - N - decrease volume gain (-25%) CUSTOMIZE EVERYTHING: If you prefer other shortcuts, want to adjust step increments, or want to configure per-site speed rules (e.g. automatically disable on Google Meet, Microsoft Teams, and Zoom), head into the Settings Dashboard and customize it to your heart's content. You can also export or restore your settings anytime with portable JSON backup files.
