How we mark our AI videos

1. What is made with AI

• Santa and his workshop: the scenes were made once with video-generation models, and every video uses them.
• Santa’s voice: speech synthesized from the message you write, with ElevenLabs models.
• His lip movements: generated to match that speech, with sync. models.
• The move into the closing scene: a few frames in between, generated by an interpolation model.

Your photo, if you add one, is not changed by AI: ordinary video editing places it into a ready-made scene as it is. The background music is mixed in the same way.

2. Where we say it

• On the order form, where you confirm, before you pay, that you understand Santa is made with AI.
• On the video’s own page, in a line under the player, which everyone the link reaches can see.
• At the bottom of every page of this site.

3. The marking inside the file

Every video carries Content Credentials, the open C2PA standard for where media comes from: a record inside the MP4 file, digitally signed by Clip from Santa and time-stamped, saying that the video was created with generative AI. It contains no personal data: not the child’s name, not your message, not your order.

The file’s comment field says the same in plain words, so any player that shows a file’s details shows it.

Sharing can remove both: many messaging apps and social networks re-compress videos and drop what is stored in the file. That is why the video’s page says it too.

4. How to check a video

Checking is free and needs no account with us. Download the video from its page first (“Download the video”), so you check the file as we made it.

• In a browser: open contentcredentials.org/verify and drop the video in. It shows the Content Credentials, who signed them and that AI was used. The site is run by the Content Authenticity Initiative, not by us.
• On a computer: the free, open-source c2patool prints the whole record and checks the signature.
• In a media player: the file’s details (for example, in VLC) show the comment.

We sign with our own certificate, which is not yet issued by a certificate authority on the C2PA trust list, so a checker may call the signer “unknown” or “untrusted”. The signature is still valid, and it names Clip from Santa. If a video’s Content Credentials name someone else as the signer, or say the file was changed after it was signed, it didn’t come from us in that form.

Journalists, fact-checkers, researchers and authorities can also ask us whether a video comes from us: write to contact@clipfromsanta.com.

5. Please keep the marking

Our Terms of Service don’t allow removing or altering the marking on purpose. An app or platform that drops it on its own when you share the video doesn’t break that rule.
