Video Metadata Viewer

Inspect what a video file actually contains: video and audio codecs, resolution, frame rate, duration, bitrate, and every stream in the container. This is what you check first when a file will not play somewhere. It is free, needs no account, and adds no watermark to your result.

Questions

Common questions.

Why will my MP4 not play in a browser?

Usually the codec rather than the container. Browsers expect H.264 video with AAC audio; an MP4 holding HEVC often will not play. Check the codec here and convert if needed.

What is the difference between container and codec?

The container, such as MP4 or MKV, is the wrapper. The codec, such as H.264 or HEVC, is how the video itself is encoded. Compatibility problems are usually about the codec.

Why does my video have no sound?

If no audio stream is listed, the file genuinely has none, which commonly happens after an export with the audio track disabled.
