Well, you’re basically describing a summary, versus a detail, response.
The person posting the video links was giving a detail response, and not a summary response.
Instead of repeating everything in detail in text of what the videos state (which would be time intensive and duplication of effort) just see the videos instead.
Even a sentence or two would help me judge if it’s worth my time. If I’m in public and don’t have headphones I’m not watching a video, especially if I have no idea what it is. If you tell me why I should care about the video I might make a note to watch it when I get home.
Secondly, I’m not just going to click a random link. I have no idea if it’s even relevant or a bot or a troll who just puts the links in every thread they come across.
which would be time intensive
The 5 minutes it would take them to type a quick summary is much less time intensive than the hour it would take everyone who sees the post to watch the videos and see if they care.
