MOV AI video check: QuickTime containers and credentials

A QuickTime MOV uses the same box structure as MP4 and can carry a C2PA manifest in a uuid box along with creation dates in its headers, and isGenAI validates the manifest in the C2PA checker and reads the headers in the video metadata viewer.

Content Credentials found

A signed manifest describes how the file was made.

Signer, recording tool, actions and the signature check result are reported separately, so you can weigh each one.

Where MOV keeps provenance

MOV is Apple’s QuickTime container, the ancestor of MP4, with ftyp, moov and mdat boxes. The C2PA specification covers it alongside MP4 through a top-level uuid box. iPhones write capture dates, device model and, on supported models, camera credentials into MOV; AI video exports from tools that sign output can do the same.

Exporting through an editor normally rewrites the container, and a social upload re-encodes it.

What isGenAI reads from a MOV

The C2PA checker accepts MOV and validates the manifest. The video metadata viewer reads MOV headers in your browser: brands, tracks, timescales, durations and raw dates, interpreted carefully because zero dates are common. The video frame extractor works with any MOV your browser can decode, within 200 MiB and ten minutes, and produces PNG stills for image checks.

Fragmented or unusual MOV layouts are reported as such rather than guessed at.

Advice

For a video from a phone, check the MOV before converting it; a converted MP4 is a new file. For an AI export, ask the creator which tool produced the MOV and whether it signs output. The MP4 and Sora pages give the vendor details.

Trace reposts to the first upload and request the original.

How to check a file in this format

  1. Keep the original bytes. Do not open and re-save the file in an editor before checking it.
  2. Use the tool that accepts the format: the AI image detector for PNG, JPEG, WebP, AVIF and TIFF; the C2PA checker for those plus HEIC, PDF, MP4 and MOV.
  3. Read each finding with its source field. The report names the container record it came from.
  4. If you must convert, convert a copy and compare both files with the image metadata compare tool so you know what the conversion dropped.

Frequently asked questions

Does isGenAI accept MOV?

Yes. The C2PA checker validates MOV manifests, the video metadata viewer reads MOV headers up to 512 MiB, and the frame extractor works with browser-decodable MOV files.

Can a MOV carry C2PA Content Credentials?

Yes. The C2PA specification covers QuickTime through the same uuid box used for MP4.

Does converting MOV to MP4 keep the credentials?

Only if the converting tool supports C2PA and preserves the box; most rewrite the container and drop it. Check the original MOV.

Why are the header dates zero?

Many encoders leave creation and modification times unset. The viewer shows the raw value and does not invent a capture time.
