Video Inspector

Before editing or publishing a video, first understand what the browser can decode. Video Inspector reads native metadata and captures a poster frame without heavy transcoding.

Object URLs are revoked when you choose another file or leave the page. Codec names, GOP structure, audio tracks and container atoms are not exposed by HTMLVideoElement, so this tool reports only browser decoded metadata plus estimated average bitrate.

FAQ

Why not transcode?
Client-side transcoding is heavy. This first version intentionally uses browser-native metadata only.
