MediaInfo is a GUI and CLI program that can display many properties about a media file. We typically install MediaInfo via homebrew, using brew install mediainfo. Once installed, you can run it by inputting mediainfo /path/to/file.ext. MediaInfo will print out many properties by default, including (for video): format, codec, file size, duration, bit rate, frame rate, track ID, width, height, DAR, color space, chroma subsampling, and color primaries.
This utility has a number of uses, including:
- Troubleshooting track encoding and missing audio
- Finding odd framerates
- Confirming vendors used appropriate specifications
- Finding best-quality items in born digital collections
- Finding when an item was encoded
- And, of course, seeing any of the specifications that don't normally show up in a file's properties
