QuickTime (.mov) Metadata Reader

Data

Read a QuickTime .mov file's duration, dimensions, and video/audio codec identifiers directly from its moov/mvhd/trak atoms, plus its creation/modification dates and any udta user-data metadata tags, without decoding a single frame.

Drop in a QuickTime .mov file and get its duration, dimensions, and video/audio codec identifiers straight from the container's own moov/mvhd/trak atom structure, the same box format MP4 inherited from QuickTime. Unlike the site's MP4/WebM Video Info tool, this one also surfaces the mvhd creation and modification dates (stored as Mac-epoch seconds and converted to ISO 8601) and any udta user-data metadata tags such as title, artist, copyright, or description, the kind of tags a camera or editing app writes into a .mov file's own header. Nothing here decodes a single frame, demuxes sample data, or transcodes anything.

Frequently asked questions

How is this different from the MP4/WebM Video Info tool?
That tool reads the same kind of atom structure but only reports duration, resolution, and codecs. This one is QuickTime-specific: it also converts the mvhd creation/modification dates (stored as Mac-epoch seconds) to ISO 8601 and extracts udta user-data tags like title, artist, and copyright that the MP4/WebM tool doesn't surface.
Does this decode any video or audio?
No, it only reads the moov box's header atoms (mvhd, trak, tkhd, hdlr, stsd, udta). No frame is ever decoded, no sample data is demuxed, and nothing is transcoded.
What if the file has no udta metadata tags?
The metadata object is simply empty; not every .mov file has user-data tags written into it, especially ones exported by software rather than recorded by a camera.
Why might createdAt be missing even though the file has a creation date?
If the mvhd box's creation_time field is zero (some encoders never set it) or decodes to a date clearly outside a sane range, it's omitted rather than shown as an incorrect 1904 or 1970 date.
