All my video ideas start as a phrase that I write down in a notepad app on my phone. Most usually come from me waking up at 2 am, and typing gibberish in that usually related to a dream. Sometimes its a random phrase in conversation taken out of context. Sometimes I just type words for the sake of typing words. I then force myself to figure out what I meant later from that gibberish. For example, a recent note I wrote myself simply consisted of, "Space Whales".
After reviewing the phrase later, I came up with the idea for a sketch where I'm paranoid about Space Whales coming for me because I have realized the true meaning of the universe. Now that I have that cohesive thought, I write that in a little notebook I keep with me. I use this notebook as "filtration" for keeping good/plausible/unique ideas. In my notebook I also write out, shot lists, props, stuff I need to do/get for sketches and anything else video related.
Finally, if I decide I like something enough or start coming up with enough ideas for a sketch, I write it out as a full script using celtx. This usually takes me an hour or so depending on the script but never much more than that. I don't really have a specific place I do this nor do I have like any sort of music, food, ritual, or anything that I do thats real special. But that's my writing process.
Sidenote: Im claiming ownership over that space whales concept so dont go getting any ideas
i normally just make up the words when im recording but when i collab with my friend Callan Wills on a series i write in the dining room
