After activating the plugin all you do is paste in the google Calendar code:
Here is a gif showing the process:
The same very small (375kb) video uploaded directly to a blog and to a sway.
Will this work?
Yup, what I did was make a Sway, it only has a Title Card and a Video Card. I uploaded a mpg4 to the video card of around 100mb.
I made the sway public.
I pasted the url of the sway into the blog editor on a line by itself.
This is a bit of a kludge but it allows you to post video of over 50mb and embed it in a Glow Blog. It could be useful if you do not have access to a public video repository.
in my first try it looks like, in this browser (Safari, mac) the video is playing using Flash.
You need to have activated Jetpack plugin and shortcode module if you are pasting in iframe embed code.
