YouTube video embed goes funky

Hey Giorgio,
I see: <iframe width="1170" height="878" src="https://www.youtube.com/embed/LLfMoF1Crhk?feature=oembed" frameborder="0" allowfullscreen=""></iframe>
What’s the code you use for embedding it?

That’s the point, it gets that from unknown source.
Normally when you just paste in https://youtu.be/LLfMoF1Crhk it used to embed nicely the video, but now it goes very much at max-width.

I’m wondering if it has to do something with WP itself or YT.
Any idea other than creating an <iframe> with specific width/height?

Tried this? https://themesandco.com/snippet/embedding-youtube-video-right-way-customizr/

[embed width="640" height="360"]https://youtu.be/LLfMoF1Crhk[/embed]

That did the trick nicely and faster/easier than creating an <iframe>

Thanks!!
