MP4 metadata
MP4 containers may include creation dates, duration, dimensions, track and codec records, bitrate clues, GPS/location tags, device labels, encoder names, and custom ISO Base Media File Format boxes.

Search all fields
Field not found: search native fields as well as the summary. If parsing finished and it is still absent, it was not found in this copy. That cannot distinguish a field never recorded from one removed later.
Check reading limits
Reading incomplete: a damaged block, unsupported format or interrupted parser is a reading limit, not an empty record. Read the warning and keep the original before trying another supported copy.
Compare the sources
Value present: dates, names and coordinates record what the file says. They are editable. Compare source groups and the history of this copy before treating a value as evidence.
Video: duration and codec describe playback. Container dates need not be filming dates. Cleanup does not remove subtitles, speech or images in the frames.
What video metadata can you view?
A video file can carry production clues that playback hides. ViewExif puts useful container, track, timing, location, and software fields into one readable report while keeping the original paths available.
- Video
- Resolution, duration, frame rate, bitrate, and dimensions for the visual stream.
- Audio
- Video codec, audio codec, channels, sample details, and track records.
- Date & time
- Creation date and modification date when the container records them.
- Location
- GPS coordinates when a camera or app wrote a valid location pair.
- Device
- Camera, phone, recorder, or device details when they are embedded.
- Software / encoder
- Encoder, editing software, handler names, and authoring labels.
Common video metadata fields
Field names differ between containers, but these labels are a useful starting point for MP4, MOV, and other supported video files.
| Field | What it can show |
|---|---|
Resolution | The stored frame width and height, such as 3840 × 2160. |
Duration | The container duration and the time base used to report it. |
FrameRate | The recorded or declared video frame rate when available. |
Bitrate | Video, audio, or overall bitrate clues saved by the container. |
VideoCodec / AudioCodec | The codecs used by each media stream and their track details. |
GPSLatitude / GPSLongitude | Coordinates written by a camera, phone, or recording app. |
CreateDate / ModifyDate | Creation and modification timestamps stored in the file. |
Encoder / Software | The encoder, camera app, or editing software that wrote the file. |
Tracks | Video, audio, subtitle, timecode, and other track records. |
Container details worth checking
MP4 and QuickTime files often keep useful records beside the encoded streams. The viewer reads what is actually present; it does not invent missing fields.
MOV / QuickTime metadata
MOV files can retain QuickTime creation and modification dates, camera or device descriptions, location strings, handler and encoder details, chapters, and separate video, audio, or timecode tracks.
How to view video metadata
Choose a clip, let the local parser read its container, then review the report without sending the video anywhere.
- 01
Choose a video
Select an MP4, MOV, MKV, WebM, AVI, FLV, or another supported video.
- 02
Review the report
Scan duration, resolution, codecs, bitrate, tracks, dates, device details, and software labels.
- 03
Check location when present
If GPS coordinates are stored, ViewExif puts them near the top of the result with an optional map link.
- 04
Keep the file private
The video stays in your browser tab. ViewExif does not upload, play, transcribe, or analyze its frames.
Why inspect video?
Video metadata can explain duration, dimensions, codecs, tracks, dates, and editing software.
Container facts
Check delivery details
Read duration, frame size, track counts, codecs, bitrate clues, brands, and rotation across nine common video extensions.
Inspect a video Production contextTrace stored history
Find creation dates, handler names, encoder labels, comments, and other fields left by cameras and editing tools.
Read local fields Provenance checkLook for signed evidence
Metadata remains editable. Use the C2PA viewer when you need to check an embedded signed provenance claim.
Verify C2PAHow the video scan works
The browser reads container metadata in this tab. It does not upload, play, transcribe, or analyze the video frames.
- 01
Choose one video
Select one MP4, M4V, MOV, MKV, WebM, AVI, FLV, 3GP, or 3G2 up to 100 MB. It stays in this browser tab.
- 02
Verify the real container
ISO BMFF brands, EBML, RIFF, and FLV signatures are checked before the filename is trusted.
- 03
Read tracks and tags
Local parsers and ExifTool WASM inspect movie headers, track records, codecs, dates, and readable custom fields.
- 04
Build the video report
Duration, dimensions, codecs, tracks, hashes, warnings, and native paths become searchable and exportable.
- 05
Forget the video
Clear, replace, or refresh to terminate the task and remove the in-tab report.

What this report cannot prove
- M4V is reported as its underlying MP4 container family.
- Video frames, speech, faces, subtitles, and visible text are never analyzed.
- Video playback, transcoding, repair, and metadata removal are not included.
Frequently asked questions
Is my video uploaded or saved?
No. Local parsers and ExifTool WebAssembly read the video inside this browser tab. The file, filename, hashes, tags, and report are not posted to an upload endpoint or saved to a viewing history.
Which video formats and fields are supported?
The viewer supports MP4, M4V, MOV, MKV, WebM, AVI, FLV, 3GP, and 3G2 up to 100 MB. It reads available duration, dimensions, codecs, frame rate, bitrate, tracks, brands, dates, encoder labels, comments, and native container fields.
Does the tool watch, transcribe, or fingerprint the video?
No. It reads container boxes and stored metadata without decoding frames, recognizing faces, listening to speech, or creating a media fingerprint.
Why can a duration, codec, or stored date look wrong?
Damaged indexes, unusual codecs, and editing software can leave stale or conflicting labels. Dates also use different time bases across containers. Treat the report as stored evidence, not a fresh media decode.
Can video metadata prove a clip is original?
No. Container labels, dates, and encoder names are editable. A signed C2PA credential can provide stronger file-binding evidence when present, but it still has a specific scope.
What is a video metadata viewer?
A video metadata viewer reads descriptive and technical fields stored inside a video container without playing the frames. ViewExif presents those fields as a searchable local report.
What metadata can an MP4 file contain?
An MP4 can contain creation dates, duration, resolution, codecs, bitrate, tracks, GPS or location tags, device labels, encoder names, and custom container boxes.
Can videos contain GPS location data?
Some cameras and recording apps write GPS coordinates or location strings into a video. ViewExif shows valid stored coordinates and does not guess a location when they are missing.
How can I see when a video was recorded?
Choose the video above and look for its creation or recording date in the report. The date comes from the container and may be absent, stale, or expressed in a different time zone.
Can metadata show which device recorded a video?
Sometimes. A camera model, phone name, handler, encoder, or software label may identify the recording device, but these fields can be edited or omitted.
Is my video uploaded?
No. The video stays in this browser tab while local parsers read it. The file, filename, hashes, metadata, and report are not posted to a server or saved to a history.
