A little stability goes a long way. Since Evan has k subscribers to his channel, it gives me visibility in front of an audience that I may not have. Whatever you do, make sure the captions are accurate. You can produce a viral video using just the phone in your pocket and a free video editor.
Facebook native videos have more impressions than YouTube videos shared on Facebook. People on Quora are looking specifically for in-depth information that solves their problems. Oh, and make sure you get a link to your channel!
Second, add a backdrop. As long as you give away something valuable, you should have no problem getting featured.
So tweet those videos! Seriously, your iPhone and Android devices are pretty much all you need. Surprisingly there may be easier wins in adapting and animating print or outdoor advertising, itself inherently designed for quick and instant communication, than trying to squeeze 30 or 60 second videos down into a newsfeed friendly format.
Then, see if any keywords bring up video results.
