Whether you're on the Starter, Lite, Pro, or Business you can download the mp4 of each event. If you're an attendee and trying to download an event, please note that you won't have access to this feature.
Here's a quick tutorial on how to do that.
First go to "My events" and select the past event you want to download.
Next click on "Options" located at the top right of your screen.
From there you'll see a drop down menu where you could select "Download HD Video"
Once you select it, your download will begin automatically.
