Found the video I was referencing in class yesterday… It wasn’t on No Film School after all (hence the delay!)
The important thing(s) to remember is(are) that the storyboard is:
a) pretty essential,
b) a guide to visualise your filming,
c) a working document… not a work of art! You really don’t have to be good at drawing.
If you want to use a template, a quick Google* image search for ‘storyboard templates‘ will give you plenty to choose from/adapt/etc…
