I'm not exactly a fan of writing my ideas down, because they seem interesting at first, but suddenly become sloppy in development.
My latest idea was series I was working on where I am trapped in my garage and I had to complete odd tasks in order to get supplies to survive. My garage was pretty much sound proof, but to avoid any more noise, the character I would be playing would be mute. When I actually got to work on it, it had too much sloppy camera work and terrible acting that I decided to scrap it in the editing process...
The only actual project I was able to finish was my "Stealth" video which took me 2 weeks to make:
Anyways, I'll write down a list of stuff I've though of:
-vlog style of camera work, randomly generated topics and sorta act them out, similar to improv
-take requests of random food combinations to eat, can be tasty or even disgusting
-use fiverr in combination with vlogging
-dropping a camera down the stairs in slow motion to see the effect it gives (this one was made when I was 12)
-practing moves on parkour (again, thought up when I was 12)
Other ideas I had usually resulted in 2-4 person limit, so they were scrapped immediately
Example:
(this is an example of a video me and my (twin) did when I was 12 and just wanted to be a simple filmmaker)
Anyways, good luck and hope you have a sudden brain burst. (Don't use a dictionary to define those two words.... :S)
