Fixed Margins below videos...

Hi All

Struggling with something I thought would be simple, but is proving anything but...

I'm trying to create a page of videos, each video has a project title placed underneath it.  I need a way to define a fixed margin between the video and its corresponding title. So that when a user scales browser, the margin between the two remains fixed/locked.

If you view : https://studioyoung.com/test  and scale browser, you will see how project title moves all over the place. 
The plan is to have say 6-8 videos on this page, so I'm looking for a solution that can be applied to each individual video and corresponding title.

Hope that makes sense.

Appreciate any help!

Titles look fine. Can you take some screenshots of problem?
