Frequently Asked Questions

What is the difference between coded size and display size?: Coded size refers to the actual pixel grid stored inside the file. Display size is what a media player should show after applying any pixel aspect ratio or rotation metadata. They often differ for footage recorded on smartphones.
Does this upload my file to inspect it?: No. The file header is read locally in your web browser. You can verify this by watching the network tab in your browser developer tools - no media data is ever transmitted.
What formats are supported for inspection?: The inspector supports a wide range of common formats including MP4, WebM, MOV, and MKV. If the browser can parse the container, the details will be displayed.

Accepted formats: Any video, Any audio
