Get metadata from a video in the terminal

On a Debian-based system (but presumably, other distributions will also have mediainfo in their repositories):

$ sudo apt-get install mediainfo
$ mediainfo foo.mp4

That will spew out a lot of information. To get, for example, the length, resolution, codec and dimensions use:

$ $ mediainfo "The Blues Brothers.mp4" | grep -E 'Duration|Format  |Width|Height' | sort | uniq
Duration                                 : 2h 27mn
Format                                   : AAC
Format                                   : AVC
Format                                   : MPEG-4
Height                                   : 688 pixels
Width                                    : 1 280 pixels

You can use exiftool. To install it run:

sudo apt-get install libimage-exiftool-perl

Then to get the metadata from mp4 file run:

exiftool video_file.mp4 > medatata.txt

The output saved in the file should be something like this:
