Video Codec Inspector
Look inside your video file without uploading it. See its real container, video and audio codecs, frame rate, resolution, duration, bitrate evidence, and what the file can—and cannot—tell you.

Important notes
Optional local preview
Preview depends on your browser's codec support. It does not change the parsed results.
A better way to understand a video.
A video's file extension describes its container—not necessarily the codecs inside. For example, MP4 may carry different video and audio encodings, and playback support depends on the device and browser.

Frequently asked questions
Is this the same as FFprobe or MediaInfo?
No. This lightweight browser-only inspector parses selected container metadata without native binaries or a server. It does not fully decode packet streams, inspect every codec property, calculate precise VFR distributions, or provide exhaustive MediaInfo/FFprobe compatibility.
Why is the bitrate sometimes missing or marked approximate?
MP4 sample tables may reveal total per-track encoded sample bytes, allowing a derived bitrate. File-wide bitrate uses total file size and duration, including overhead. WebM, AVI and MPEG-TS metadata does not always provide a dependable per-stream bitrate.
Does a successful inspection guarantee the video will play?
No. A metadata signature can exist in a corrupt, encrypted or truncated file. Browser playback support also varies across operating systems, devices and codec profiles.
Are large files uploaded or fully loaded into memory?
No. Inspection uses bounded slices of local File objects and does not upload data. Exceptionally large movie headers or unsupported structures are reported as partial. Optional video preview may cause the browser to read more data for playback.
