Really nice! I'm also currently playing around a lot with automatically generated videos and I can see this having a lot of potential! Some questions that come to my mind: 1. Do you plan including AWS Polly in the speech generation? There is also a free tier, the API is nice so it might be also a good choice for people using AWS SDK already in their projects. 2. How do you approach aligning the words with animations? Is it possible to align it for a specific word? I was wondering how one might approach this. Did you already describe it somewhere?
