About Firgie & its limits

Firgie is a pilot first-to-register video registry. It compares the picture and the soundtrack of a video against videos already registered with Firgie and reports the earliest matching entry. Copies that are mirrored, zoomed, cropped to vertical, or framed with black or blurred bars are usually caught.

What a result means

• First registered means the earliest matching entry in Firgie's registry — not authorship, copyright ownership, or a legal finding.
• Time is server-recorded, not independently certified.
• Firgie only knows about videos registered with Firgie. A result here says nothing about videos elsewhere.
• A match does not establish infringement.
• Confidence is shown as a category (high or possible), never as a percentage or probability.
• A signed receipt reflects what Firgie signed at the time. A record's current status (active, disputed, revoked or withheld) is on its page, and that status takes precedence.

Known matching limits

• Heavily cropped reposts, and reposts where the platform's buttons or captions were removed or added, may be missed or only reach “possible”.
• Talking-head or mostly still videos filmed in the same place can look alike. Firgie needs the sound to tell them apart; without it they reach at most “possible”.
• Reaction videos that show the registered video in a small window are recognised mainly by its sound, so they reach “possible”, not “high”.
• Videos that share only a trending song or sound reach at most “possible”.
• Very short clips, videos of mostly black or still frames, and rotated copies or copies re-filmed from a screen may be missed.
• Checking a long or 4K video can take a few minutes.

A low or missing match is not proof that a video wasn't derived from another.
