Video Intro for Tutorials

Our videos (_mostly tutorials for now_) require brief view of the @dwyl logo at the start & end
to give viewers a consistent experience.
These intro are often referred to as a "reveal" or "sting" and sometimes as a "bumper".
a few examples: https://youtu.be/CB8xi9X9okM
_Alternatively_ we could just have a Video Title as the intro. e.g: https://youtu.be/mbPn8b_Li_w

> I like MKBHD's 3 second intro https://youtu.be/2BQ1rCqG19Y because it's short & simple.

We could just _buy_ a template from: https://videohive.net/search?term=logo+reveal
as suggested by:
https://youtu.be/0C47nyXsdDc

> I would _prefer_ to _create_ something that didn't look "_generic_"
> but I'm _conscious_ of the fact that we don't want to spend "_too much_" time/money on this.

## Required
+ [x] Research existing video intros (_please share examples of ones you like_)
+ [x] Decide if we should **make _or_ buy** the intro
+ [ ] what sound effect or music should we play in the background during the intro?
+ [x] decide if we should have an "outro" (_and should it be similar/different to the intro?_)
