Video Metadata Viewer

Inspect video file info: duration, resolution, aspect ratio, frame rate, MIME type and file size.

Header bytes are sniffed locally for container/codec fourccs (avc1, hev1, av01, vp09, mp4a, Opus…); duration/resolution come from the browser’s own decoder. Big files are scanned head+tail (6 MB each) only.

About Video Metadata Viewer

Inspect video file info: duration, resolution, aspect ratio, frame rate, MIME type and file size.

Video Metadata Viewer reads the technical header of a video file and lays out every detail that editors, uploaders and support teams usually hunt for. Open a clip and you instantly see its duration, resolution, aspect ratio, frame rate, MIME type, codec, container and file size presented in one readable panel. Those numbers settle practical questions before an upload: whether a clip meets a platform limit, why an editor refuses to import it, how two copies of the same footage differ, or which file is the true high resolution master. Nothing is transcoded, no frame is re encoded, and the file never leaves your device, so even large recordings open in a moment. Video Metadata Viewer handles the formats your browser can play and works offline as a free tool for quick checks.
