How it works

The browser decodes the video container header in memory and surfaces native width, height, duration, and track statistics.

When to use this tool

  • Verifying video dimensions match ad or social media platform specifications.
  • Confirming whether a muted clip actually contains an audio track.
  • Checking exact video duration down to fractional seconds.
