This was a couple of day long demo I wrote for someone with a non-games use case in mind. Obviously this isn't my project, and at present I'm not sure how much I can say, so I won't talk too much about it here. Instead I'll just say that it's a really stupidly over-engineered solution for what it does, but there is kind of a reason for that.
This is a project built in Unreal Engine which uses command line arguments to produce a .mp4 file of the sentence you pass in. The way it works scales incredibly poorly because for every word you want, it produces a single .png file which is then fed into ffmpeg to produce an mp4 file.
