- After export: Verify an export has the expected resolution and length.
- Quick reference: Identify unknown files by codec, duration, and container.
How video metadata works
Basic fields come from the browser’s video element and the file object. Detailed stream info is gathered using local in-browser media engine probing when available. No server is involved.
What you see
- Duration: Total length in minutes:seconds and seconds.
- Resolution: Width × height in pixels.
- Aspect ratio: Simplified ratio (e.g. 16:9) and decimal ratio when available.
- File size & type: Size and MIME type.
- Streams: Video/audio tracks, codec names, bitrate, FPS, sample rate, channels, and tags.
Frequently Asked Questions
What metadata is shown?
Basic info: duration, resolution, aspect ratio, file size, name, extension, and MIME type. When available: bitrate, codecs, streams, track list, and container tags.
Is my video uploaded?
No. Everything runs locally in your browser. Nothing is sent to any server.
Why does preview sometimes not show?
Some codecs aren’t playable in every browser. Even if preview fails, the tool may still read metadata. Try another browser if needed.
Which formats are supported?
Common formats like MP4, WebM, MOV, AVI, MKV, M4V, OGV, 3GP, WMV, and FLV are accepted. Support depends on your browser.
Can I edit metadata with this tool?
No. This tool only displays metadata. Use a dedicated metadata editor to change tags.
