MarkN Video Speed od MarkN

A lightweight extension that puts video and podcast playback speed
behind a single keypress — no more digging through player menus.

Slow down, speed up, or return to normal with a single key.
Works on YouTube, Netflix, podcasts, online courses, and other sites
that use HTML5 media.

━━━ Only 3 shortcuts to remember ━━━

• Slow down (default: S)
• Speed up (default: D)
• Toggle 1.0x ⇄ your target speed (default: G)

That is all you need to learn. No menus to navigate.
Each action can be rebound to any A–Z or 0–9 key.

━━━ A speed indicator that stays out of the way ━━━

So it does not disrupt your viewing, the speed indicator
(such as "1.50x") appears at the center of the screen for just a
moment when you change the speed, and fades out in about 0.3 seconds.

You can confirm the current speed at a glance, without opening the
player's settings menu. It also works in fullscreen.

━━━ Speed persists across sessions ━━━

Once set, your speed is retained across tab switches, video changes,
and browser restarts.

Settings are stored via chrome.storage.local only. They are not
synced to a Google account, and they do not leave your device.

━━━ Re-applies speed when sites reset it ━━━

YouTube and a few other sites silently reset playbackRate to 1.0x
after an ad, a seek, or a quality change.

This extension watches for those moments and reapplies your chosen
speed automatically.

━━━ Embedded players, audio, local files ━━━

• YouTube / Vimeo / SoundCloud embeds in blog posts
• <audio> elements — podcasts, audiobooks, web radio
• Video files opened locally in the browser

The same shortcuts and HUD apply everywhere.
