Videos
Associate a fingerprint with a specific video file.
Two videos with the same name or similar images may be technically different files. Kicklinks calculates a SHA-256 fingerprint of the video file received and associates it with the available proof information.
The complete file is uploaded for processing.
The fingerprint and proof information are retained; the original video file is not retained after processing.
Real-world situations
A video can be cut, re-edited, re-encoded or imitated using AI, then shared as your original version.
What can happen
- An excerpt cut in a way that changes its meaning.
- Another version published after delivery of the file.
- An altered edit, soundtrack or encoding.
- AI-generated or AI-altered content attributed to you.
How Kicklinks helps you
Create private evidence tied to the exact version of the video processed.
Compare the exact file
The name and images may look identical. The fingerprint may differ.
Demonstration — fictitious data

The observation: the name is identical, but the fingerprints differ.
These two videos are different files at the byte level. Exporting, recompressing or re-encoding may produce a different fingerprint, even when the images look similar.
Illustrative comparison, not a verifier result.
The fingerprints are fictitious and shortened. No file is uploaded and no engine call is made. This comparison does not detect editing, deepfakes or content manipulation.
From the received file to the proof
An exact fingerprint, without retaining the original.
- 01
The video file is uploaded.
The complete file is uploaded for the checks provided by the Kicklinks pipeline.
- 02
Its fingerprint is calculated.
A SHA-256 fingerprint is calculated from the exact file received.
- 03
Technical information may be extracted.
Depending on the file and processing pipeline, a thumbnail and duration may be produced.
- 04
The proof information is retained.
The fingerprint and associated information are retained according to the existing proof model. The original video file is not retained after processing.
Supported formats
Video files recognised by the existing flow.
The applicable maximum size is shown when you upload.
- MP4
- WebM
Some MOV or M4V files may be accepted when recognised as compatible MP4 containers.
The flow does not promise format conversion or transcoding.
Information associated with the file
The declared context remains separate from the fingerprint.
A title, platform or URL may be provided within the existing flow. This information is declared by the user. It is not an independent observation by Kicklinks of the video's actual publication.
Fingerprint
It corresponds to the exact video file processed.
Declared context
It describes the information provided about the file.
Date and status
They reflect the information actually available in the proof.
A strictly private result
The video proof stays in your private space.
The private record brings together the proof identifier, SHA-256 fingerprint calculated by Kicklinks, and available date, status and history. A private PDF may be generated on request.
The original is not retained after processing. A private thumbnail may be available, but it is neither a certified copy nor a return of the video.
The scope of the proof
An exact fingerprint for a specific video file.
The processed file
The SHA-256 fingerprint is associated with the exact bytes of the video file received.
An identifiable technical difference
Different fingerprints correspond to technically different files.
Proof information you can consult
The private record can display the fingerprint, date, status and declared context that are actually available.
Limits stated clearly
A fingerprint does not describe the truth of the images.
The fingerprint of the exact file is established. That fingerprint alone does not establish the content's authenticity, author, filming conditions or truthfulness.
- It does not automatically identify the author.
- It does not prove when or where the video was filmed.
- It does not prove that the video was never edited before the proof was created.
- It does not detect deepfakes.
- It does not compare the visual similarity of two videos.
- It does not guarantee the truthfulness of the images or statements.
- It does not provide a legal assessment of the content.
- It does not prove rights to use or distribute the video.
- It does not guarantee an external or qualified timestamp.
- It cannot identify a re-encoded video as the same video based solely on its visual content.
