Motivations

When I needed to interpolate clips (make them longer by generating new in-between frames), I had to export them from After Effects, import the resulting clips into Flowframes, wait for the interpolation to finish, and finally import the interpolated clips back into After Effects. I had to repeat this process every time I wanted to interpolate a clip, which was very boring, required tons of clicks and attention ; despite being the optimal way to do it.

Since I love doing automation and creating little software, I decided to create a script that could interpolate a selected clip directly in After Effects : no external software, just one click, and no sacrifices on quality (since uwu2x uses the same AI as Flowframes, it's all good). A few months later, I made it an extension to get a better UI. Since it could also help everyone who had the same "workflow issue" as me, I shared my little creation, made showcase videos, created a website, coded a system to see how many people were using it over time (I love statistics), which features were popular, get feedback, and make updates : like a real developer in a company, but at my humble scale and for fun since I find doing this as a hobby quite W :D
