What is Jump Cutter?

'Jump Cutter' is a sophisticated Firefox add-on that enhances your video-watching experience. By either fast-forwarding or skipping the silent portions of videos, viewers effectively get to consume content ~1.5x faster. This is particularly effective for long, unedited videos like lectures, webinars, podcasts, or video on demand (VOD) content, where pauses can fill a significant segment of the video's duration. The add-on also offers adjustable video speed controls and handy keyboard shortcuts.

Plays silent parts of videos on the page at a faster speed, or skips them entirely. Useful for watching lectures, stream recordings (VODs), webinars, podcasts, and other unedited videos, where the speakers spend a portion of time on things other than talking. Can also just control video speed, without skipping silence. Has hotkeys (keyboard shortcuts).
