About Video Metadata Viewer

The Video Metadata Viewer allows you to inspect comprehensive technical and file properties of any video stored on your device directly in your web browser. Utilizing native HTML5 File and Media APIs, the tool determines exact frame dimensions (width and height), calculates standard aspect ratios (e.g., 16:9, 9:16, 4:3, 1:1), identifies video orientation (landscape, portrait, or square), classifies the resolution category (4K UHD, 1080p Full HD, 720p HD, etc.), and computes duration down to the second alongside file size and approximate container bitrate. Processing occurs locally in your browser with zero server uploads, keeping your video files private.

Common Practical Use Cases

1

Verifying video dimensions and aspect ratio before uploading to social platforms (TikTok 9:16 vs YouTube 16:9)

2

Checking exact container duration and bitrate for bandwidth planning

3

Inspecting video file size and resolution tier for technical documentation

How to Use Video Metadata Viewer

  1. 1Choose a video file from your computer or mobile device, or drag and drop it into the upload box.
  2. 2The browser extracts and calculates all video stream properties immediately.
  3. 3Review the structured metadata dashboard organized into File Info, Video Stream, and Technical specs.
  4. 4Use the built-in preview player to verify the video playback or check specific timestamps.
  5. 5Click "Copy Metadata" or "Export JSON" to save the extracted properties to your clipboard or notes.
  6. 6Click "Choose another video" or "Remove video" to inspect a different file at any time.

Practical Worked Examples

Inspecting Smartphone Vertical Video

Sample Input / Scenario
Reel_Video.mp4
Computed Result / Action
Resolution: 1080x1920 (Portrait 9:16) | Tier: 1080p Full HD | Duration: 00:00:45 | Bitrate: ~4.2 Mbps

Explanation: Confirms video is formatted correctly for vertical short-form platforms.

Supported Formats & Specifications

Accepted Inputs:

  • MP4, WebM, Ogg, and browser-supported video formats

Generated Outputs:

  • Formatted metadata report
  • Exportable structured JSON payload

Key Features & Technical Capabilities

  • Client-side metadata inspection with zero server uploads
  • Detailed video dimensions and exact pixel resolution (width × height)
  • Automatic aspect ratio calculation (16:9, 9:16, 4:3, 1:1, 21:9, etc.)
  • Orientation detection: Landscape, Portrait (vertical), or Square
  • Resolution tier classification (4K Ultra HD, 1080p Full HD, 720p HD, SD)
  • Exact duration formatting with millisecond precision and human-readable time
  • File size analysis with byte-level accuracy and estimated container bitrate
  • One-click metadata summary copy and JSON export for developers and editors
  • Built-in lightweight local video preview player with memory-safe cleanup

Under the Hood: Browser Processing Architecture

  • Inspects HTMLVideoElement.videoWidth, videoHeight, duration, and File.size; computes GCD for aspect ratio math.

Browser Limits & Edge Cases

  • Standard browser APIs expose container-level metadata; deep elementary NAL units are not demuxed.

Common Mistakes to Avoid

  • Confusing display scaling with true native videoWidth/videoHeight.

In-Browser Video Frame Processing & Privacy

Client-Side Media Stream Pipeline

The Video Metadata Viewer tool leverages native HTML5 Media, WebCodecs, and Canvas frame extraction entirely in-browser. Video streams are processed in local memory buffers without cloud transcoding queues or remote caching. Standard static web assets and client runtime scripts are delivered securely via CDN over encrypted TLS (HTTPS).

Frequently Asked Questions

What is video metadata?

Video metadata encompasses information embedded in or associated with a video file, such as its container format, pixel dimensions (width and height), display aspect ratio, playback duration, file size, and creation/modification timestamps.

Does this tool upload my video to a server?

No. The Video Metadata Viewer processes your video locally within your web browser using HTML5 File and Media APIs. Your video data remains entirely on your device and is never transmitted to an AllAdvanceTools server.

Can I export the extracted metadata?

Yes. You can copy the formatted technical readout directly to your clipboard or export it as a clean structured JSON file for developer pipelines.
