Glad you got through making the video, but maybe it was a little unclear what I meant -- a short ~15 second GIF of moving about the app (not an introduction, but when you're being productive with it) would do much more to draw people in.
By all means though, embed the video onto the page -- it's at least a start. IMO it's not really reasonable to expect busy devs to sit through 1 minute of silent sped-up introductory content.
Here are some examples of what I mean (I searched "wysiwyg react" and "page builder react" on github and picked some good examples):
