Choose the file
Select or drop one local video. Inspection starts automatically.
Video Metadata Viewer
Read the technical properties of a local video before troubleshooting or re-exporting it. Check the container, codecs, dimensions and estimated frame rate without uploading or modifying the file.
Inspect one local video
Choose a file to start inspection automatically. The tool reads file structure; it does not play or decode the picture.
How to check video properties
2
Read the summary
Wait for the results, then check container, dimensions, codec and duration. Missing fields may be unavailable.
3
Open the detailed data
Review metadata and expand Raw data for track names, languages, codec parameters and available keyframe timestamps.
4
Keep the details you need
Select and copy text manually before choosing another file. There is no report-download or dedicated copy button.
Understand the file before changing it
Video and audio properties
Read available duration, size, container, display dimensions, rotation, codecs, audio presence and sample rate.
Compare with requirements
Check the reported codec and dimensions against the receiving app’s requirements instead of relying on the filename extension.
Read-only and local
Your source stays on your device and is not altered.
Supported containers
Try MP4, MOV, WebM or MKV. The file must be readable by this parser.
Free without an account
No credits or sign-up. Inspect one file at a time.
Bounded inspection
Frame rate is sampled and keyframe scans can be partial; check coverage information alongside the results.
Video files to inspect
MP4, MOV, WebM and MKV are starting points, not a guarantee for every file. AVI, WMV and FLV are not supported by this inspector.

Example: an MP4 that an editor rejects
MP4 names the container, not the video codec. If this report shows HEVC while the receiving editor requires H.264, the mismatch is a useful lead. Check that editor’s requirements and export settings, then inspect the new file again. Renaming the extension does not change its codec.
For format changes, see the video converter; for file-size reduction, use the video compressor. Browse all free tools.
Video inspection questions
Is the video metadata viewer free?
Yes. No account or credits are required, and inspection does not change the source.
What else can the report contain?
Available HDR indication, embedded tags and location information may appear. Raw JSON includes track details and coverage flags. There is no bitrate field; metadata depends on what the source and parser provide.
Is my video uploaded?
No. The file is parsed locally. Copy any needed results before leaving or refreshing; there is no saved cloud report.
Does a successful inspection prove the video will play?
No. Reading the container and packets is different from decoding them. A readable codec label does not prove playback or upload compatibility, and this tool does not repair the file.
What if inspection fails or a field is missing?
An unsupported or damaged container can fail. An unavailable value does not mean zero or an absent feature. There is no fixed file-size/duration cap, but resources and parser support still matter.
Are FPS and keyframe counts exact?
FPS is estimated from up to 120 packets, not a full variable-frame-rate analysis. Keyframe scanning stops at 10,000 entries; a partial result is marked. The report includes at most 128 tracks.
Can this verify quality, authenticity or AI generation?
No. Resolution, sample rate and HDR flags describe technical properties, not visual/audio quality. Embedded tags can be absent or edited; they do not establish authenticity or detect AI content.
