Hi @ASBG,
Apologies this has taken so long to get a solid answer, I will be taking this up with the team.
The reason the other video is outputting differently is it’s being processed by the FitVids.js script, which keeps the video aspect ratio intact, and resizes the video so that it is perfect across all viewport widths.
The script has just been updated with ignore selectors, so I’ll get this setup for the next update, and you’ll be able to disable the behaviour with ‘no-resize’ as the class on the video iframe.
Can I ask why you’d rather it not be responsive?
Apologies once again for the delay, I’ve assigned to myself so that I can respond from here on.
