Patreon is a membership platform first and a video host second, which shapes how saving video works there. There is no download button by design, and member video playback is validated against your login session and membership tier every time it plays. That validation is exactly where screen recorders (black screen from protected playback), browser extensions (cannot reproduce the logged-in session), and command-line tools like yt-dlp (fail on login and membership checks) tend to break. The content plays fine in your browser; turning that playback into a saved file is the hard part.
VidMost handles it from inside the authenticated session. The built-in Chromium browser signs into your Patreon account, you open a creator page or member post you have access to, and a few seconds into playback the smart sniffer either detects a standard stream — surfacing a download prompt with the quality options Patreon serves your session — or, when no directly sniffable stream is available, browser recording mode records the browser-rendered playback. Quality is whatever Patreon decides to serve your session, commonly 480p to 720p; VidMost saves that picture faithfully but does not manufacture a higher resolution than the platform provides. For the common case of a whole course or lesson library, the batch queue lets you add each video and process the set sequentially.
Saving is scoped to membership access, and use is scoped to Patreon’s terms and the creator’s authorization. VidMost is the right tool for keeping personal offline copies of content you support; it is the wrong tool for redistributing a creator’s paid work.
