Jump Cutter Extension

⏩ Skips (or fast-forwards) silent parts in videos in real time and completely automatically.

🌐 Supports YouTube, Coursera, Twitch, local files, and (almost) any other website.

Useful for watching 👨‍🏫 lectures,🔴 stream recordings (VODs), 🎙️ podcasts, webinars, 📞 call & audio recordings, and other unedited videos where the speakers spend a portion of time on things other than talking.
But even if the video is tightly packed, it can also save a bit of time, so it's generally fine to keep it always on.

🕵️🚫 Fully offline and local. Does not track you or send your data anywhere.

🔃 Easy to turn on and off, without having to reload the page (it's there to save time after all!).

⚙️ Has a lot of different settings, but generally you won't have to constantly tune them or touch them at all.

⌨️ Has a lot of handy shortcuts (hotkeys): control video playback and extension settings without using a mouse (or eyes).

🆓🍺 Completely free, both as in \"freedom\" and as in \"free beer\" (at least for now):
Licensed under GNU Affero General Public License v3.0 or any later version (AGPL-3.0-or-later) — the most based license out there.

David Katsina (ID: 000000e7c68f4db5) Voted 1 ★ - Updated 11/08/2023 заикания

Jason Walls (ID: 000000d524ba2b98) Voted 5 ★ - Updated 08/30/2023 This is absolutely phenomenal, perfect for watching unscripted YouTube webshows that have lots of pauses. My favorite use for it is for watching Critical Role - it makes watching that show 10x better and can cut out a good 10% or more of boring silence at times. If I could give the creator one suggestion, it would be to add a whitelist feature with wildcard support, so that one could make this extension only work on certain YouTube playlist urls, for example. A blacklist feature would be nice too. Those would just be luxuries, as the hotkey to toggle the extension does work fine already (as long as I remember to hit it when I switch between videos I want to speed up and those I don't.)

Timofey Danilevskiy (ID: 0000003b98c830aa) Voted 5 ★ - Updated 08/28/2023 Идея - мое почтение. Немного допилить алгоритм чтоб не было заиканий звука и будет вообще пушка! Удачи в разработке!

S Patil (ID: 00000017a4766917) Voted 5 ★ - Updated 05/31/2023 Very great extension. Saved lot of time. Need playlist support. In my case - I am mixing videos from different folder so I was thinking if any sort of playlist support will help. Cheers :)
