I want to make it super easy for my user to embed a video from YouTube (maybe eventually from other sources) without having to get the iframe code. They should only have to enter the URL for the video, and maybe check a couple of optional settings, and the code will do the rest.
I'm planning to share the snippet and field architecture I develop here to save myself/others time in the future, but if someone else has already done this and wants to share first, even better!
