How Stockfilm preserves, describes, restores, and licenses archival footage.

Physical-source policy

Production footage on Stockfilm originates on physical film. The archive is built from home movie reels, primarily Standard 8mm and Super 8, with some 16mm, acquired from private collections, estate sales, dealers, and family donations. The catalog currently traces published clips to 1,600+ cataloged physical source reels.

• Reels, containers, handwritten labels, and acquisition records contribute to the metadata a clip carries. Label text is transcribed and kept with the reel record.
• Not every clip has the same level of documentation. Some reels arrived labeled and dated; others arrived with nothing but the film itself.
• Digitization does not by itself establish an exact date, location, or the identity of anyone on film. Those conclusions require evidence, and the catalog labels how strong that evidence is (see cataloging confidence below).

The preservation pipeline itself, from reel rescue through 4K scanning, is described on Archive Methodology.

Provenance

In Stockfilm's context, provenance means the documented chain from a physical source object to the published clip. The catalog distinguishes between:

• Source reel. The physical film reel a clip was scanned from, with its own record: format, reel size, and any label or notes that arrived with it.
• Original label or description. A transcription of what the filmmaker or their family wrote on the reel, box, or accompanying notes. This is primary evidence and is preserved verbatim, including misspellings.
• Stockfilm catalog description. Written by the archive during review. It can include observations and inferences (a year estimated from cars and clothing, a place suggested by signage), and those inferences are labeled as such rather than presented as documented fact.
• Technical scan record. The digitization record for each master file.
• Clip-level derivative. The published clip: a segment of a scanned reel, carrying its reel context with it.

Cataloging confidence

Date and location metadata carries one of four confidence levels. Estimated metadata is never presented as documented fact, and fields without enough evidence are left unidentified rather than guessed.

Confirmed (Supported by direct contemporaneous evidence.)

Supported by an original label, container, acquisition record, or other direct contemporaneous evidence tied to this specific footage.

Corroborated (Supported by multiple independent clues.)

Supported by multiple independent clues, such as a note on the source-reel record combined with the catalog analysis of the footage itself.

Estimated (Based on visual or technical evidence.)

Based on visual or technical evidence such as film stock, automobiles, clothing, signage, architecture, packaging, or production characteristics. An estimate, not a documented fact.

Unidentified (Insufficient evidence for a responsible conclusion.)

Insufficient evidence exists for a responsible conclusion. The field is left open rather than guessed.

Evidence types the catalog uses

• Original reel labels, container notes, and acquisition records
• Collection-level documentation that arrived with a group of reels
• Identifiable landmarks and dateable events visible in the footage
• Film-stock evidence: specific emulsions were manufactured in known date ranges
• Visual evidence: automobiles, clothing, signage, packaging, architecture, and processing marks

Confidence labels appear on clip pages next to the date and location fields. The Confirmed level requires direct contemporaneous evidence tied to the specific footage and is only assigned by human review, never inferred automatically.

Restoration

Restoration is conservative by design: correct degradation, recover what the film originally captured, and never fabricate what was not there.

• What may be corrected: color shifts from emulsion aging, exposure inconsistency, frame-to-frame flicker, gate weave and registration errors, and scratches, dust, and minor tears, addressed frame by frame.
• What is not altered: scene content, composition, and the original character of the film. Heavy damage is treated conservatively and documented rather than painted over.
• Stabilization corrects camera-gate registration without cropping away edge content.
• Frame rate and aspect ratio follow the original recording format (typically 16 to 18 fps for 8mm, 18 to 24 fps for Super 8).
• No generated content: no frames are AI-generated, extended, or interpolated, and no synthetic upscaling is used. Every frame originated on physical film.

Technology and AI

Stockfilm uses modern retrieval technology and licenses training data, and keeps both strictly separate from the footage itself. The distinctions:

• Search and retrieval. Search, visual similarity matching, and the clip analyzer use machine learning to help find footage. This technology ranks and retrieves clips; it does not generate or alter the imagery it returns.
• Metadata assistance. Some catalog fields are drafted with the help of automated analysis (for example, text read from reel labels, or content flags suggested by visual review tools). The catalog records how each assertion was made, and automated conclusions are treated as estimates unless corroborated.
• Restoration. Digital restoration corrects damage. It does not generate frames, interpolate motion, or synthetically upscale (see Restoration above).
• Production licenses. Every clip in the production-licensing catalog originates on physical film. No AI-generated footage is mixed into production search results. Standard production licenses do not include AI-training rights: the licensing system records an AI-training prohibition on every production asset.
• Dataset and model-training licenses. Stockfilm separately offers dataset licensing for machine learning under a distinct written agreement. See AI Training Data. A production license is not a dataset license, and a dataset license is not a production license.
• Synthetic outputs. Stockfilm does not sell AI-generated or synthetic historical imagery.

Rights and content flags

A Stockfilm direct license grants the rights identified in the applicable license agreement: a royalty-free, worldwide, perpetual license to the restored master for commercial and editorial production use. Marketplace clips are licensed under the marketplace's own terms.

Catalog content flags identify visible people, minors, logos or trademarks, artwork, and audible music where review has recorded them. Their limits:

• Content flags are screening aids and are not legal opinions. Their presence or absence does not determine whether a proposed use requires additional review.
• Flags combine automated detection with catalog review; automated detection can miss elements or misread them.
• Clips without a recorded review show their flag status as not recorded, never as cleared.
• Depending on footage, context, territory, and proposed use, a production may need to evaluate privacy, publicity, trademark, artwork, location, music, or sensitive-use considerations that sit outside the licensed copyright.

The Licensing Guide covers the license itself; For Archival Producers shows how these boundaries fit a production workflow.

Collection limitations

Home movies are valuable primary records, but they are not neutral or comprehensive. They reflect who had access to cameras, where filmmakers traveled, what they chose to record, and what material survived. Geographic, social, and demographic representation therefore varies across the archive, and coverage depth varies by place, period, subject, and surviving source material.

Clips by decade (searchable catalog, live)

Ten most-represented countries (live)

160,768 clips carry a country. Concentration is real: the United States dominates, and depth outside it varies widely. A country's presence in the archive does not imply deep coverage of it.

Of the 217,000+ digitized and restored masters, 162,000+ clips are published in the searchable catalog and 115,000+ are available for direct licensing from Stockfilm; the remainder are licensed through marketplaces or still in cataloging.

Privacy and customer data

The practices below describe what the systems on this site do today; the Privacy Policy is the governing document.

• Search activity is logged (query text, result counts, clicked results) to run autocomplete, improve retrieval, and monitor abuse.
• Production briefs and footage requests are delivered to the archive team as email and are used to answer the request.
• Research boards are stored server-side, are private to the browser that created them, and are only readable by others through an explicit share link, which the owner can revoke.
• Payments are processed by Stripe; Stockfilm does not store card numbers.
• Dataset licensing is a separate agreement; production customers are not part of any dataset by default.

Retention periods and processor details live in the Privacy Policy. Where this page and the Privacy Policy differ, the Privacy Policy controls.

Corrections and metadata updates

Researchers, filmmakers, collection donors, families, and viewers sometimes know more about a clip than the catalog does: a street they grew up on, a relative on film, a date that must be wrong. Corrections and additional information are welcome.

• Submissions include the clip or reel ID, the proposed correction, and the supporting evidence.
• Submissions are reviewed by the archive against the reel record and the footage; they are not applied automatically.
• Accepted corrections update the catalog record and its confidence level.
