It's actually pretty easy to make short, single thought videos on your iPhone!
There's even a YouTube channel about that!
Clarify your intended goal, message
Set Up your camera, lighting, and setting
Shoot 3 versions (test, actual, and backup)
Review Does it 'work'? Make it.
Promote it by sharing across all your services.
Videos are available on Eljaes' YouTube channel.
Let's play around and see what we come up with, yeah?
