Interesting, how long ago did you first see runwayml & decide to teach yourself machine learning?
I started taking Coursera courses back in late fall/early winter 2020. I discovered RunwayML through my subscription to Corridor Crew on YouTube, where they demoed the tech back in January of this year.
I'm currently working on a fully-automatic version of this based off some excellent research from the University of Washington. It's still in its infancy, but if you'd like to follow my progress, I post occasional updates over on https://nomoregreenscreen.com
This is just the beginning of what's possible in the intersection between DL and creative filmmaking, and I'm really excited to get to be in this field at a time when compute is cheaper than ever and all the information I could want is available for free on the internet!
