Update:
I've managed to embed a non-standard bootstrap video size (of proportion: 4x5)... however, unlike standard bootstrap embeds it doesn't seem to obey a MAX HEIGHT anywhere i put it - on the iframe, or divs around it.
(to see the issue, view the page, and view full size - the tall phone video shows the issue... is way too tall)
any ideas how to fix, or ways around it?

and adding this CSS:
/* Custom aspect ratio for 4x5 video */
.embed-responsive-4by5 {
padding-bottom: 125%; /* 5/4 aspect ratio */
}
Docs I've bene referring to re: embeds, and custom ratios:
Behind the scenes, Bootstrap uses the following formula:
.embed-responsive-XbyY {
padding-top: 100% * Y / X;
}
Which means you can add your own class to your custom CSS, if you don't feel comfortable recompiling Bootstrap or overriding its variables:
.embed-responsive-4by5 {
padding-top: 125%;
}
