About the free video metadata viewer
Every video file carries a technical passport: which codec the frames are encoded with, the exact resolution and frame rate, how many bits per second the encoder spent, which audio tracks are inside, and a set of freeform container tags where cameras, phones, and editing software leave notes about themselves. Tools like MediaInfo have exposed this on the desktop for years. This page does the same job instantly in your browser: the file's container structure is parsed locally, no frames are decoded, and nothing is uploaded. Because only a few kilobytes of headers are actually read, even very large files report in about a second, and it works in browsers without WebCodecs support too.
The report covers the container format, duration, and MIME type, then each video track with codec, resolution, rotation flag, frame rate, and measured average bitrate, then each audio track with codec, channel layout, sample rate, and bitrate, and finally every descriptive tag stored in the container.
Reading the numbers that matter
The codec answers most compatibility questions: H.264 plays everywhere, H.265 saves space but chokes older devices and some browsers, VP9 and AV1 live mostly in WebM files and streaming pipelines. The bitrate is the quality budget: a 1080p clip at 12 Mbps has plenty of headroom, while the same clip at 1.5 Mbps has already been squeezed hard, and re-compressing it further will show. If a file is much larger than its content deserves, the bitrate row tells you immediately, and the free video compressor fixes it. The rotation flag explains the classic phone video mystery: footage that plays upright in one player and sideways in another is stored rotated with a flag that some software ignores.
What hides in container tags
Beyond the technical fields, containers carry descriptive tags: a title, comments, the name and version of the software that encoded the file, capture device details, and sometimes location data written by phones. None of it affects playback, but all of it travels with the file when you share it. Screen recorders and editors are especially chatty here. If you would rather publish a clean file, the free video metadata remover strips every tag losslessly, without re-encoding a single frame. For photos, the image metadata viewer does the same job for EXIF data.
Formats and privacy
The viewer reads MP4, M4V, MOV, WebM, and MKV files, which covers phone footage, screen recordings, downloads, and exports from every mainstream editor. Since parsing happens on your device, there is no file size limit, no queue, and no privacy question to answer: confidential footage stays confidential, and checking a hundred files costs nothing. If the report shows your video's resolution is lower than you need, that is a job for Upsampler's AI Video Upscaler, which reconstructs real detail up to 4K.
