Hey, what helped me getting video done when nothing is working out is to first of all throw that project to the back of my mind (its never as important to get done ASAP as i tend to believe it is) and then just roll tape on whatever catches my eye in the moment even if i'm never gonna watch it again. if you have pets, a nearby road intersection or sidewalk, or even some intrepid birds and squirrels out the window, these are all evergreen subjects!
that keeps me thinking like a videographer and eventually the inspiration i needed comes all on its own!
