Highlight a video file

Hi, I am new to PKM and obsidian.

I see that almost everything is based on text, pdfs, webs …
How can you manage video or audio in such a system?

I mean to extract or classify information that is in a video. Something like making a highlight in an area of a video just like you do in a pdf.

In youtube it is possible to extract a url that contains the exact time, but how do you do this in a local video or audio?
Is there a way to save these cool parts you find to a media file?

Perhaps this issue is more for Zotero than obsidian. Is it possible to do something like this in Zotero or other software?
