Changing aspect ratio for specific videos. (16:9 -> 9:16)

Hi to the community and team who developed this amazing plugin! My question is, hopefully, easy to solve: what html code do I have to write before/after my “httpv://” link to change the aspect ratio for specific videos on my website? For instance in the WP YouTube Lyte settings I set full-size video using 16:9 ratio (widht 1280px max) but sometimes I need to insert video using the 9:16 ratio instead (recorded with a phone).

Thanks in advance for helping me!
