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 little popup, on virtually any site. Speed it up, keep live streams on the live edge, and even out loud and quiet sounds. No accounts, no tracking, nothing leaves your browser. PLAYBACK SPEED • Editable presets and a fine slider — one click or drag, on almost any video. • Set your own preset values and raise the maximum speed as high as you need. • Remember a speed per YouTube channel, per site, or globally — applied automatically next time, by priority (channel → site → global). • An optional on-video badge shows the current speed and the real time left at that speed. Drag it anywhere on the player. KEYBOARD SHORTCUTS • Slower, faster, and reset keys, a hold-to-speed key, and a key per preset. • All remappable to the key chords you prefer — no mouse needed. LIVE STREAMS (YouTube Live, Twitch, and more) • Live-sync catches you back up to the live edge after a pause or a stall, then returns to normal speed. • See the true latency to the broadcaster, not just the buffer. • Rewind a live stream: scrub back and watch the recording at any speed, then jump to the live edge and it's a live stream again. AUDIO COMPRESSION • Evens out loud and quiet parts so you stop reaching for the volume — clear dialogue, no blasting explosions. • Start from a Voice, Night, or Movie preset, or fine-tune every knob yourself. • A live meter shows the effect; an auto mode can follow the speech rate. MORE • Super theater on YouTube — one toggle makes theater mode fill the whole window, and the header hides itself. • Live graphs for audio levels and the live-stream buffer. • Light and dark themes, 10 languages.
