Check a video for AI metadata and Content Credentials

OpenAI says every Sora video carries Content Credentials, and some cameras add them too. See what a video file says about where it came from, which app saved it and where it was filmed.

What it reads

Content Credentials (C2PA): the app named as the maker, whether the record says generative AI made it, the steps it lists, the files it was made from and who signed it. Then the file’s own tags: creation date, camera make and model, GPS location, the encoder, Apple and Android fields, and any XMP block. MP4, MOV, M4V and 3GP files; WebM and MKV aren’t read yet.

What a clean result means

Very little on its own. Content Credentials often disappear when a video is re-saved: in our tests a plain copy through FFmpeg, with no re-encoding, dropped them every time. So “none found” can mean a phone video, or an AI video that was edited or passed through another app. Invisible watermarks such as SynthID sit in the picture and sound, and no file check can see them.

Your videos stay with you

The video is read on your own device, a few kilobytes at a time: the picture and sound are skipped, so a 2 GB file opens as fast as a small one. Nothing is uploaded, nothing is stored, and you don’t need an account.

From our tests

What Sora and Veo videos carry, and what survives a re-upload
Seven sample videos opened box by box, fifteen FFmpeg copies checked, and a lossless remover proved frame by frame.
