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.
