Video Info Inspector

Check local video file size, duration, dimensions, aspect ratio, type, extension, and estimated bitrate in your browser.

MP4, WEBM, MOV, and other browser-readable files work best.

Browser preview

This inspector reads browser video metadata and is designed for browser-side processing based on the current public implementation. It does not load ffmpeg.wasm.

Quick answer

A video info inspector shows file size, duration, dimensions, aspect ratio, type, extension, and estimated bitrate.

This page is lighter than conversion tools because it uses browser metadata instead of ffmpeg.wasm.

Best inputs

Browser-readable files

MP4, WebM, and MOV are the safest choices for duration and dimension reading.

Planning before processing

Check size, duration, and resolution before choosing compression, GIF, or trimming settings.

Inspection method

The browser reads the selected file metadata and estimates bitrate from file size and duration.

Duration and dimensions depend on browser codec support.

Aspect ratio is simplified from width and height.

Estimated bitrate is useful for planning but not a stream-level probe.

Example, Assumption, and Limitation

Use the result as a practical estimate or transformation, then confirm edge cases for critical work.

Example

Upload a 45MB MP4 and confirm it is 1920 x 1080, 0:32 long, 16:9, and roughly 11 Mbps before compression.

Assumption

The browser can decode enough metadata from the selected video to report duration and dimensions.

Limitation

This tool does not inspect codec names, frame rate, subtitles, audio tracks, or exact stream bitrates.

Common use cases

Use these scenarios to decide which input, assumption, or follow-up tool fits this specific task.

Compression planning

Check whether a video needs resolution or bitrate reduction.

GIF planning

Pick a short range after checking duration and dimensions.

Upload QA

Confirm file type, size, and aspect ratio before uploading.

Local review

Inspect unpublished video metadata with browser-side processing before choosing a heavier workflow.

Frequently asked questions

How is the video inspected?

The selected video is read through browser metadata APIs based on the current public implementation. Avoid using sensitive media unless you have reviewed the implementation.

Does it load ffmpeg.wasm?

No. This inspector uses browser metadata only, so it stays lighter than conversion tools.

Why are some values unavailable?

If the browser cannot decode the video container or codec, duration and dimensions may be unavailable.

Is the bitrate exact?

The bitrate shown is an estimate based on file size and duration. Actual video and audio stream bitrates may differ.
