MagnifySlider

Provides surgical, frame-by-frame scrubbing resolution on long-form video content.

MagnifySlider gives you precise control over where a paused video sits. Pause a video on YouTube, Vimeo, Udemy or Coursera and a second slider appears over the player. Drag it exactly as you would the normal one. A timer reads the position to a hundredth of a second, and you can switch between four levels of precision — from a broad span of the timeline down to a narrow window around the playhead. Press play and the slider gets out of the way. The comma and period keys step the video back and forward by one thirtieth of a second, and behave the same way on all four sites — including the ones with no shortcut of their own. WHERE IT WORKS YouTube, Vimeo, Udemy and Coursera, including Vimeo's embedded player wherever it appears. The extension does nothing on any other page. Live streams work within the rewind buffer the site keeps behind the playhead. You can scrub back through what has already been broadcast; you cannot scrub ahead of live. Works in Chrome, Edge and Brave. PRICING MagnifySlider is free to use for seven days. After that a one-time licence is required, purchased through Gumroad and activated from the extension's toolbar icon.
