If you have Youtube's app on your phone you can upload them there. It took me a while to find the exact button to push because it's not 100% self explanatory 8/. I circled the button here (honestly didn't even NOTICE it until i did a google search on HOW). After that it presents you with the option of either making a new video or selecting one you've already recorded.

And yeah, when maze isn't hiding she's climbing! Tol gurl!
