Summary should be shorter if possible

<summary>Convenient unified display of the most relevant technical and tag data for video and audio files</summary>

https://blogs.gnome.org/tbernard/2021/09/07/ready-for-software-41/ recommends 35 chars max. I think 50 would still be fine.

It is not short, right, but what is the issue with it, in practice, especially nowadays with big 16:9 screen so easily 120 chars on a terminal line?
Also, I don't see a good shorter version without cutting a lot of information about the purpose.

stores are also used on smaller screens and not terminal only. linux phones are also starting to become a possibility.

In isolation a long summary is okay, but if you have 20 on your monitor, it's more unlikely to make you read them.
