QuickTime metadata in MP4 and MOV videos
QuickTime metadata can control how MP4 and MOV videos display capture dates. If these fields are missing or interpreted differently, videos may appear out of order.
Microsoft Store will be the recommended path when the link is available. The classic installer remains available from the site.
Unsigned .exe noticeThe .exe installer is not signed yet. Windows or the browser may show warnings during download or installation. To avoid those messages, use Microsoft Store once the link is available.
When this guide helps
This matters when videos come from phones, cloud exports, messaging apps or older backups.
A repair process should check how the target viewer reads the file after metadata is changed.
What usually goes wrong
The most expensive mistakes happen when an entire batch is changed before the source metadata is understood. In large libraries, one wrong decision multiplies quickly.
- Changing a field that the destination ignores.
- Confusing UTC and local time.
- Repairing photos and videos with one rule.
- Not keeping a copy of originals.
Recommended safe method
The most reliable path is to work from a sample, keep a backup and record each exception. That protects the archive and makes the result easier to explain later.
- Inspect video date fields first.
- Compare sidecar data where available.
- Run a small repair sample.
- Open the result in the target library before processing all videos.
How MetaVault Studio fits
MetaVault Studio includes video-aware metadata workflows so MP4/MOV files are not treated as simple photo equivalents.
The focus is local processing: your photos and videos are not automatically sent to a server. The site and server handle license, purchase and support only when those flows are used.
Checklist before processing everything
- Did the video remain playable?
- Was the date interpreted correctly?
- Were unsupported files listed?
- Is the report clear enough to review later?
How this appears in the MetaVault Studio workflow
The app is designed to import a folder, apply or extract metadata, track progress and review results through a report. That turns metadata repair into a verifiable process.
Transparency and limits
Not every lost metadata field can be reconstructed. When there is no reliable source, the best result is to separate the case for review instead of inventing information. Google, Microsoft, Apple, ExifTool and other names mentioned here belong to their respective owners; use is descriptive.

Common questions
Can I process the whole library at once?
The safer path is to start with a sample. After dates, reports and exceptions are validated, the same profile can be applied to the full batch.
Does MetaVault visually change my photos?
The metadata workflow is meant to write or extract information, not recompress the visual content. Still, keep a backup and use copy mode when there is risk.
What happens to files without reliable metadata?
They should appear in the report or in review folders. This keeps uncertain files from silently contaminating the final result.
