Find out what is inside a video file: resolution, duration, frame rate, codecs, bitrate, audio format, rotation and more. It reads the file locally, so the video is not uploaded, and it also tells you whether your browser can decode it.
The answer card at the top shows what you asked for, and the full details are underneath, with copy and JSON export.
Choosing the right tool
- Check the frame rate and resolution before uploading to a platform with requirements.
- Look at the codec if a video will not play: HEVC and ProRes are the usual culprits.
- A rotation value explains videos that are sideways in some players.
Questions
What can the checker show?
Container, duration, resolution, aspect ratio, rotation, video codec and profile, frame rate, frame and keyframe counts, bitrates, and audio codec, sample rate and channels.
Is it as detailed as MediaInfo or ffprobe?
It shows the most useful details that a browser can read. Specialist tools show more, such as color spaces and HDR metadata.
