Video Metadata Viewer

Video Metadata Viewer reports what is actually inside a video file: container, duration, codecs, resolution, frame rate, pixel format, audio channels and every stream it finds.

The file is opened with no output requested, which makes ffmpeg print the header it read and then exit — and that printed header is the source of every value shown, parsed rather than inferred. You get a JSON summary and, separately, the raw engine report as a text file, so the summary can always be checked against what the engine really said. Because the format is read from the file's own header, it will contradict a wrong extension: a .mp4 that is really a Matroska file shows up as one here. This is stream and container information, not the descriptive tag set, so it is not the place to look for GPS coordinates or a creation date.

The inspection is entirely local and only the header is of any interest, so nothing is sent and nothing about the file is recorded.

Working out why a file will not play in one particular player, checking a delivery against a codec and frame rate spec, confirming whether footage is 8-bit or 10-bit before grading, and identifying a file whose extension is lying.
