Hi,
You can embed the videos inside the column shortcodes like below. This gives you more flexibility for embedding videos and having other contents right beside them.

Donec tristique hendrerit dui vitae lacinia. Suspendisse ante ligula, adipiscing porta aliquam et, rutrum nec lectus. Nulla erat risus, molestie non dapibus ac, fermentum vitae felis
About disabling the responsive. Do you want to disable the responsive functionality across the whole site or only for the videos that you embed?
Thanks.
