Download video from X/Twitter posts using yt-dlp. Use when the user wants to "download this X video", "save this tweet video", "grab video from Twitter", or provides an x.com/twitter.com status URL with a video. Handles HLS streams and uses --print after_move:filepath for reliable path detection.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Download X/Twitter Video Download video from X/Twitter posts via yt-dlp. ## Prerequisites - `yt-dlp`: `brew install yt-dlp` ## Usage ```bash python3 scripts/download_x_video.py "https://x.com/user/status/123/video/1" [/output/dir] ``` Prints the downloaded file path to stdout. ## How It Works - Uses yt-dlp with `--print after_move:filepath` for reliable path detection - Handles Twitter's HLS streaming format (fragmented MP4) - Output template: `x_video_<tweet_id>.<ext>` in the specified directory ## Troubleshooting ### yt-dlp auth errors If Twitter requires login, yt-dlp may need cookies: ```bash yt-dlp --cookies-from-browser chrome "https://x.com/..." ```

How to install
mdr add swyxio/skills/download-x-video@sha256:346dbcea5430b39eThe line at the top of this page pins the label git:20260514.e386fac, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
