Thank you so much for getting back to me so quickly. I have Gutenberg disabled because I wish to use the subhead field (and for other reasons). Because of what you told me, I was able to find the VIDEO tab and the Soledad VIDEO shortcode insert, so all works well. I want to tell you, for whatever it's worth, that the post style needs to be either 1 or 2 for the player controls to show up on the video, but that's okay for what I want, too, and I thank you for pointing me in the right direction!
