Common Use Cases for Video Metadata Viewer
Pre-Upload Quality Check
Verify resolution, aspect ratio, and duration before uploading to YouTube, Vimeo, or a CDN. Our video metadata viewer confirms your video meets platform requirements without uploading the file anywhere.
Content Creator Workflow
Content creators use the video metadata viewer to quickly check exported video specs — resolution, duration, and file size — before publishing. Confirm your 4K export is actually 3840×2160 and not accidentally downscaled.
Debugging Encoding Issues
Developers and video engineers use the video metadata viewer to diagnose encoding problems. Check whether a video is landscape or portrait, verify the container format, and confirm the aspect ratio matches expectations.
File Management and Cataloguing
Quickly identify video files in a folder by dropping them into the video metadata viewer. Get resolution, duration, and file size at a glance — useful for sorting, renaming, and organizing large video libraries.
Client Deliverable Verification
Video editors use the video metadata viewer to verify deliverables match client specifications before handoff. Confirm the correct resolution, duration, and container format without opening a full NLE application.
Pre-Edit Planning
Before importing footage into an editing timeline, use the video metadata viewer to check frame rate, resolution, and duration. Plan your edit sequence settings to match your source footage and avoid transcoding issues.
Understanding Video Metadata
Learn what video metadata is and how the video metadata viewer extracts it
What is Video Metadata?
Video metadata is the technical information embedded in or derived from a video file that describes its properties — resolution, duration, frame rate, aspect ratio, file size, container format, and codec. Unlike audio metadata (ID3 tags), most video metadata is structural rather than descriptive: it tells software how to decode and display the video stream correctly. Our video metadata viewer extracts this information using the browser's native HTML5 Video API, which reads the video container headers without decoding the full stream — making it fast and completely private.
How Our Video Metadata Viewer Works
- Drop or select your video file: The video metadata viewer accepts any video format your browser supports — MP4, WebM, MOV, MKV, AVI, OGG, and more. The file is loaded into browser memory using a local object URL; it is never uploaded to any server.
- Instant metadata extraction: The HTML5 Video API reads the container headers and reports resolution, duration, and aspect ratio. Codec hints are inferred from the MIME type and file extension. A thumbnail is captured from the first second of the video using the Canvas API.
- View, copy, and download:All metadata fields are displayed in organized groups with individual copy buttons. Use "Copy All Metadata" to export a complete text report. Download the extracted thumbnail as a JPEG image.
What the Video Metadata Viewer Displays
- Resolution: The exact pixel dimensions of the video frame (e.g. 1920×1080, 3840×2160, 1280×720).
- Aspect Ratio: The width-to-height ratio in simplified form (e.g. 16:9 Widescreen, 4:3 Standard, 9:16 Vertical).
- Duration: Total playback length in hours, minutes, seconds, and milliseconds, plus the raw decimal seconds value.
- Frame Rate:Estimated frames per second using the browser's
requestVideoFrameCallbackAPI where supported.
Codec Hints and Limitations
The HTML5 Video API does not expose the exact video or audio codec — it only reports whether the browser can play the file. Our video metadata viewer infers codec possibilities from the container format and MIME type. For example, an MP4 container most commonly uses H.264 video with AAC audio, while WebM uses VP8/VP9 or AV1 with Vorbis or Opus audio. For precise codec identification (including profile, level, bit depth, and bitrate), use a dedicated tool like MediaInfo or ffprobe. The video metadata viewer is designed for quick, browser-based inspection — not as a replacement for professional media analysis tools.

Frequently Asked Questions About Video Metadata Viewer
Common questions about viewing video metadata online
A video metadata viewer is a browser-based tool that reads and displays the technical properties of a video file — resolution, duration, aspect ratio, frame rate, file size, container format, and codec hints — without uploading the file to any server. Our video metadata viewer uses the HTML5 Video API to extract this information locally in your browser. No signup required.
The video metadata viewer supports any video format your browser can play, including MP4, WebM, MOV, MKV, AVI, OGG, 3GP, FLV, MPEG, and M4V. Browser support varies by format — MP4 (H.264) and WebM are universally supported, while MKV and AVI support depends on your browser and operating system.
Absolutely. The video metadata viewer processes your file entirely in your browser using the HTML5 Video API and Canvas API. Your video is never uploaded to any server, stored, or transmitted anywhere. All metadata extraction and thumbnail capture happen locally on your device with complete privacy.
Yes — the video metadata viewer is 100% free with no signup, no account, and no usage limits. View metadata and download thumbnails for as many video files as you need, completely free forever. No premium tier, no ads, no file size restrictions.
The HTML5 Video API does not expose the exact codec used in a video file — it only reports whether the browser can decode the stream. The video metadata viewer infers likely codecs from the container format and MIME type (e.g. MP4 → H.264/AAC, WebM → VP9/Opus). For precise codec identification including profile, level, and bitrate, use a dedicated tool like MediaInfo or ffprobe.
The video metadata viewer seeks to approximately 10% of the video duration (or 1 second, whichever is shorter) and captures a frame using the HTML5 Canvas API. The thumbnail is exported as a JPEG image. This process runs entirely in your browser — no frames are sent to any server.
Frame rate detection uses the browser's requestVideoFrameCallback API, which is available in Chrome and Edge but not in all browsers. When the API is unavailable, the video metadata viewer omits the frame rate field rather than showing an inaccurate estimate. For guaranteed frame rate detection, use MediaInfo or ffprobe.
Yes. The video metadata viewer works on any modern mobile browser that supports the HTML5 Video API — including Chrome for Android and Safari for iOS. File selection uses the native file picker. Note that some mobile browsers have limitations on which video formats they can decode.
