Video Keeper 作成者: HippoSF

Video Keeper finds the videos on the page you're viewing and saves them to your Downloads folder as ordinary MP4 files.

WHAT IT DOES
• Video files on a page (video players, links to MP4/WebM files) — one click to save.
• Streaming video (HLS): choose the quality, watch the progress, cancel any time. Streams are joined into a standard MP4 that plays in any video player. AES-128-encrypted streams are supported.
• YouTube on Mac: install the free, Apple-notarized Video Keeper Helper app (optional). It runs the open-source yt-dlp downloader and keeps itself up to date.

HOW TO USE
Open a page with a video, click the Video Keeper button and click Download. If nothing is listed, start playing the video and open the button again.

LIMITATIONS
Video Keeper can't save copy-protected (DRM) video such as Netflix, Disney+ or Prime Video, or live streams. YouTube downloads need the helper app, which is available for macOS only; everything else works on every platform.

PRIVACY
Video Keeper collects no data — no accounts, analytics or tracking.

PLEASE DOWNLOAD RESPONSIBLY
Only download videos you have the right to: your own, openly licensed ones, or where the website allows it.
