Sora video provenance
Sora video watermark & C2PA checker
Inspect an exported Sora MP4 or MOV file up to 20 MB for C2PA Content Credentials, QuickTime metadata, encoder tags, and structured OpenAI provenance. Frame-level marks remain a separate visual review step.
- MP4 and MOV provenance scan
- C2PA validity and trust
- Exact container coverage
Provider verification
Sora Watermark Checker is coming soon
We are connecting and validating the provider-specific verification required for dependable results. This page will open when that check is ready.

Use the AI Watermark CheckerHow the Sora watermark checker works
This checker reads supported container and metadata records from the submitted video. It reports a C2PA state only when the validator returns one; it does not inspect video frames or make an origin verdict.
Structured C2PA status
Validation, trust, issuer, generator, and actions appear only when the available validator returns them.
MP4 & QuickTime metadata
Container boxes, encoder tags, and creation software fields - inspected without decoding or touching your video frames.
Visible mark review
A visible moving logo lives in decoded video frames, so the report keeps it as a clear visual-review step.
Export-specific report
Exports and platform re-encoding vary. The result records which provenance layers survived in this submitted video.
Evidence you can use
Every report separates cryptographic credentials, declared metadata, and provider-controlled verification. You can see exactly what ran before deciding what the file proves.
- C2PA Content Credentials parsing and cryptographic validation for supported files.
- Declared EXIF, XMP, IPTC, container, and generator metadata evidence.
- A precise boundary and official path for provider-controlled verification when one exists.
Frequently asked questions
What can this page check in a Sora video?
It inspects supported MP4 and QuickTime metadata plus any C2PA manifest returned by the validator. A result describes the supplied file only; it does not prove where the video was made.
How is a visible Sora watermark checked?
The report lists visible moving marks as a frame-level visual review because they live in decoded pixels. The automatic pass focuses on MP4/MOV container metadata and C2PA provenance.
What video metadata is checked?
MP4 and QuickTime container boxes, encoder tags, creation software fields, and C2PA/JUMBF manifests when present. Metadata-only inspection never touches your video frames.
Can I inspect an older Sora export?
Yes. Upload the original or least-reencoded MP4/MOV export available. Screenshots, transcoding, and platform uploads can strip C2PA and metadata, so the closest copy to the original export gives the strongest file-level provenance report.
Does re-encoding remove Sora provenance?
It can. Transcoding and platform processing often replace container metadata or strip manifests. Scan the original export first, then compare any re-encoded copy to see which file-level signals survived.
