I'm using mediainfo to obtain several aspects of an input video such as resolution and framerate. I'm using the --inform option for that with values such as

"Video;%FrameRate%"

"Video;%Format/Info%"

However, i'm not being able to obtain the information on color range the same way. Running --info-parameters , i can see that the option i believe i should be using is 

colour_range              : Colour range for YUV colour space

But trying mediainfo with that doesn't work, instead responding with an echo, as if it didn't recognize the setting

Here's some attempts i've done:

me@pc:~$ mediainfo --version
MediaInfo Command line, 
MediaInfoLib - v0.7.82
me@pc:~$ mediainfo video.mp4 --inform="Video;%Format/Info%"
High Efficiency Video Coding
me@pc:~$ mediainfo video.mp4 --inform="Video;%FrameRate%"
30.000
me@pc:~$ mediainfo video.mp4 --inform="Video;%FramRate%"

me@pc:~$ mediainfo video.mp4 --inform="Video;%colour_range%"
%colour_range%
me@pc:~$ mediainfo video.mp4 --inform="Video;%Colour_range%"

me@pc:~$ mediainfo video.mp4 --inform="Video;%somethingweird%"
%somethingweird%

I know for a fact that this video does have the metadata, because running plain mediainfo gives me: 

{...}
Video
ID                                       : 1
Format                                   : HEVC
Format/Info                              : High Efficiency Video Coding
{...}
Color range                              : Full
Color primaries                          : BT.709
Transfer characteristics                 : BT.709
Matrix coefficients                      : BT.709
{...}

So right now i'm looking at the very serious possibility of just using plain mediainfo and grep to obtain what i want, but i'm wondering, maybe i'm just missing the correct name in mediainfo?

This is mediainfo 0.7.82 running on ubuntu 16.

Any tips would be appreciated

mediainfo video.mp4 --inform="Video;%colour_range%"

This is the expected command, so something was buggy in the version provided in Ubuntu 16.04, MediaInfo v0.7.82 is pretty old and no more supported upstream, you should update to a newer one, there are .deb files and also a repository for automatic updates at the MediaInfo Ubuntu dedicated page, MediaInfo 18.12 is available also for Ubuntu 16.04.

~$ more /etc/issue
Ubuntu 16.04.6 LTS \n \l
~$ mediainfo --version
MediaInfo Command line,

~$ mediainfo test.265 --Inform="Video;%colour_range%"
