Video Metadata Viewer
Use Video Metadata Viewer, review the result, and keep the original until the output is checked.
How to use Video Metadata Viewer
- Select a video file to inspect.
- Read the reported properties: file name, size, type, duration, pixel dimensions, aspect ratio and resolution.
- Open Technical Analysis for the container, the average bit rate and bits per pixel - press play on the preview for about a second and the frame rate measures itself from the frames the browser actually decodes.
- Use Export Metadata to save the report as JSON, CSV or text, or Clear All to load another file.
What Video Metadata Viewer actually does to your file
The frame rate is counted from decoded frames, so give the preview a second of playback, and note that a variable-frame-rate phone clip reports an average rather than one fixed number; a browser without frame callbacks says it cannot measure. Everything else here is limited to what a tab can see about the media: codec profile and level, per-track bitrates and colour range need a desktop prober, and the bit rate shown is the whole file divided by its duration, which quietly includes audio. The quality reading is an estimate computed from resolution and average bitrate, useful for sorting a pile of files and not for grading one.
Video Metadata Viewer FAQ
What does Video Metadata Viewer do?
Inspect available metadata from a supported video, including exposed format and resolution fields. Review the details in your browser.
Which files work with Video Metadata Viewer?
This category commonly supports MP4, MOV, AVI, MKV, WMV, FLV, WebM, and 3GP. Use the accepted file types shown in the uploader, because support varies by browser and by the engine behind each tool.
Should I strip metadata before sharing?
If the file is going to a public audience, yes: remove location, device and author fields. Editing tools usually rewrite only some tags, so check the result rather than assuming.
Will my original file be changed?
No. The work is done on a copy in this tab by a WebAssembly build of ffmpeg, and the result arrives as a separate download, so your original is still there if you need it.
How is my file processed?
It is not uploaded. The processing is done locally by a WebAssembly build of ffmpeg, so the practical ceiling is your device's memory and the limit shown beside the uploader - no queue, no account, no copy on a server.
Is the Video Metadata Viewer free?
Yes. The Video Metadata Viewer is free with no trial limit, subscription, or watermark on downloads. You can use it for personal and commercial projects without creating an account.
