Video Info Inspector Guide
Reference for checking local video duration, dimensions, file size, aspect ratio, and bitrate estimates before compression, conversion, trimming, or publishing.
Quick answer
Use Video Info Inspector before changing a video. It gives you the practical facts you need first: file size, duration, dimensions, aspect ratio, and estimated bitrate.
What this tool does
The inspector reads basic media information from a local video in the browser. It helps you choose the next tool instead of guessing compression, conversion, trimming, or thumbnail settings.
Supported input
- Browser-readable MP4, WebM, and similar local video files
- Short clips, screen recordings, exported demos, and social draft assets
- Files that can be opened by the current browser media stack
Output
- Duration and file size
- Dimensions and aspect ratio
- Estimated bitrate when enough information is available
- A practical starting point for compression and publishing decisions
Step-by-step use
- Open Video Info Inspector.
- Select the local video.
- Record duration, dimensions, and file size.
- Use bitrate estimates to decide whether compression is needed.
- Use dimensions to decide whether resizing or format conversion is useful.
- Choose the next tool in the video workflow.
Data handling and processing behavior
Processing is handled in the browser for this tool based on the current public implementation. Avoid entering sensitive media unless you have reviewed the implementation and your own data handling requirements.
Limits
- Browser metadata reading depends on codec and container support.
- Bitrate is an estimate from file size and duration, not a full codec analysis.
- The tool does not inspect every stream, chapter, color profile, or professional mastering field.
- Very large files can still be slow to read on mobile devices.
Common errors
Duration does not appear. The browser may not be able to decode enough metadata from that file.
Bitrate seems approximate. It is calculated from available size and duration, so it is best for planning, not forensic media inspection.
The video opens here but fails elsewhere. Compatibility also depends on the target platform, codec, and upload pipeline.
