A QUICK WALKTHROUGH
How to use this tool
- Choose a video file.
- Wait for the browser to load its metadata.
- Review duration, dimensions, aspect ratio, file size, and estimated average bitrate.
Browser boundary
The standard video element exposes duration and dimensions. Codec and exact per-stream bitrate are not reported here. The bitrate is an overall estimate from file size and duration.
Privacy
The file is read locally and is not uploaded. The tool does not decode or export the video.
GOOD TO KNOW
Common questions
Is the bitrate exact?
No. It is an average estimate from file size divided by duration, not a per-stream field.
Can it show the codec?
No. Browsers do not expose exact codec details through this standard API.
