When several people review a short-video draft, the draft and its transcript can contain incidental personal information: a name in a source note, an email in a screenshot, or a voice that was not intended for publication. A simple review system could share a short-lived link to a redacted export rather than the full editing project, and keep the original assets with the creator. What is a practical way to balance revocation, auditability and minimal retention when review links are shared outside a team? For example, is it better to issue individually scoped links or to rely on an authenticated workspace, and what metadata should be discarded once a review ends? A URL that expires does not revoke a copy someone already downloaded, so I would be interested in the limits as well as the controls. Disclosure: I am associated with Faceless Reels AI (https://facelessreels-ai.com/), a browser-based short-video project, and used AI assistance to draft this question. This is a general design question, not a claim that the project implements the controls above.
