Read video file information

See the real resolution, codec, frame rate, bitrate, rotation and length of any video.

Runs in your browser. Nothing is uploaded.

The extension is a label anyone can change and the properties dialog is often wrong in a specific, maddening way: it reports the coded size rather than the displayed one. On anything filmed on a phone those differ, because the rotation lives in a flag — which is why a video that plays upright is listed as 1920 × 1080 when it is really 1080 × 1920 on screen.

What comes back here is the container, the codec, the display resolution, the frame rate measured from the packets rather than read from a header, the average bitrate, the length, and the rotation when there is one. Underneath, whatever the audio track is, or a plain statement that there is none.

That is enough to answer the questions that actually come up: why an editor refuses a file, why one clip in a set will not cut against the others, whether a video is really 60 fps, and why something is sideways. Nothing is written and nothing is uploaded.

  2. 2Read what each one actually is.
  3. 3Nothing is written — the files are only read.

Questions

Why does the resolution differ from what my computer shows?

Most file properties show the coded size and ignore the rotation flag. This shows the display size — what a player actually puts on screen.

Why is the frame rate not a round number?

It is measured from the packets rather than read from a header. Real footage is often 29.97 or slightly variable, and the header frequently rounds.

What can it open?

MP4, MOV, MKV, WebM and MPEG-TS, with H.264, HEVC, VP8, VP9 or AV1 inside. It reads the container, so the extension does not have to be right.
