betterXplayer от Jasper

betterXplayer is an OPEN SOURCE tool that makes long videos on X easier to watch without changing how the site feels.

Our github: https://github.com/jasperdevs/better-x-player

Hold on a video to temporarily play it at 2x speed, then release to go back to your normal playback speed. If you leave a long video unfinished, betterXplayer keeps track of it locally and shows it in a compact popup so you can jump back in later.

Features:

Hold-to-2x playback on X videos
Resume unfinished long videos from a simple popup
Ignores short clips under 60 seconds
Keeps the experience lightweight and close to X’s native UI
Stores progress locally in your browser
betterXplayer is designed to stay out of the way. There are no dashboards, accounts, ads, analytics, or extra clutter. It focuses on two things only: faster playback while holding, and getting back to unfinished videos quickly.

How it works:

Press and hold on a video to switch to 2x
Release to restore the previous speed
Videos you do not finish are saved to a compact list
Reopen the post later and continue where you left off

Privacy:
betterXplayer stores video progress locally using browser extension storage. It does not sell your data, send your watch history to external servers, or require an account.
