A local video file is different from an expiring download link
A prepared download link is temporary; a completed local file is a separate copy on your device. When the service link expires, it does not remotely delete a file you already saved. A bookmarked token URL, however, is not a durable archive of the video.

Understand the three locations
The source platform owns the upstream media and controls its access. The service temporarily prepares an output for your selection. The browser then transfers that output to a local or chosen cloud-backed folder. These locations have different lifetimes and permissions.
In the current project configuration, analysis sessions and output links expire after ten minutes, and temporary output cleanup is periodic. This is operational storage, not a permanent video hosting library. The browser must finish saving before the service link ceases to be usable.
Verify that a copy really exists
Use your browser’s download history to find a completed entry, then reveal the saved file in its destination folder. Check that its size is greater than zero and its duration and audio match your selected output. Merely opening a preview or bookmarking its URL does not perform this check.
When the destination is a synced cloud folder, distinguish the local file from a cloud placeholder. Make sure it is actually available on the device before relying on offline playback. The service cannot guarantee a separate storage provider’s sync or retention behavior.
Troubleshoot an expired token
If you have not retained a completed file, return to the original authorized public media link and analyze it again. The upstream content may have changed or disappeared, so a fresh successful extraction is required. Reusing an old token does not extend its validity.
If the local file is damaged or incomplete, preserve the error information and obtain a new output when the source remains accessible. Do not treat an HTML error response saved with a video extension as a valid archive. Keep source attribution separately from the temporary service token if you need future context.
Worked example
A browser successfully saves clip-360p.mp4 into Downloads at 12:05. At 12:20 the service token no longer works, but the saved file still opens locally. In contrast, a bookmark containing only the service URL cannot recreate the file after expiry; it points to temporary storage rather than an owned archive.
