Video Metadata Viewer in your browser, no signup
Table of contents
Read and displays a video file's technical metadata - codec, resolution, duration, frame rate, bitrate, and more - without altering the file. Useful for quickly checking a video's technical specs before uploading it somewhere with specific format requirements, or diagnosing why a video won't play correctly.
Video files are huge and desktop converters are slow to install. Use this when you need one clip smaller, quieter, shorter or in a format that actually plays.
Video Metadata Viewer is a good fit when checking codec compatibility before client delivery.
In plain English
Video Metadata Viewer is built around a few practical wins, not a long feature list:
- Provides technical clarity before publishing videos.
- Helps diagnose playback/upload rejection issues quickly.
- Non-destructive inspection of original files.
- Useful for editors, marketers, and dev teams.
How to run it
- Upload video file. Load media asset you need to inspect technically.
- Read metadata summary. Review codec, duration, dimensions, fps, and bitrate fields.
- Compare with platform specs. Check compatibility against upload/playback requirements.
- Plan fixes if needed. Decide whether to transcode, trim, or re-export asset.
Real situations
- Checking codec compatibility before client delivery.
- Investigating why platform rejects uploads.
- Auditing media library consistency.
- Preparing transcode plans for legacy assets.
Small habits that help
- Check frame rate and aspect ratio with target platform rules.
- Confirm audio codec when sync/playback issues occur.
- Track bitrate for size/quality balancing decisions.
- Use metadata snapshots in issue reports.
Skip these
- Assuming MP4 extension guarantees codec compatibility.
- Ignoring variable frame-rate quirks in editing workflows.
- Relying on file size alone instead of bitrate analysis.
- Skipping metadata checks before batch uploads.

FAQ
What metadata can I expect to see?
Typically video codec, resolution, duration, frame rate, bitrate, and audio codec/channel information - covering the key technical details that affect compatibility and quality.
Why would I need to check a video's codec?
Some platforms or devices only support specific codecs - checking a video's codec helps you determine whether it needs converting before it will play correctly on your target platform.
Does viewing metadata change the video file?
No - this tool only reads and displays existing metadata; the video file itself is completely unchanged.
