Video Tuner Pro

Tune any video: playback speed, live-stream sync and rewind, plus audio compression that evens out loud and quiet sounds.

Take control of any video on the web from one compact popup. Change playback speed with editable presets and precise controls, remember a speed per channel, site or globally, and use fully remappable keyboard shortcuts. Live-sync catches streams back up to the live edge after a pause or stall. You can rewind live streams, see true broadcast latency, smooth out loud and quiet audio with compression, and automatically ease the speed when speech becomes too dense. Viewer, Theater and native Picture-in-Picture modes help you focus on the video. The extension can remember Viewer behavior and expose Auto or fixed quality choices when the underlying player supports them. It also includes an optional on-video speed/time badge, Super Theater for YouTube, live audio and buffer graphs, light and dark themes, and 10 interface languages. PRIVACY No accounts, analytics, advertising or tracking. Settings can sync only through your own browser profile. SponsorBlock markers are disabled by default. If you explicitly enable them on YouTube, the current video ID and a fixed list of segment categories are sent to sponsor.ajay.app to retrieve public timestamps. Cookies, account data, saved settings, audio and video content are not sent. Turning the feature off stops these requests.
