I'm creating a college / corporate seminar level class with a 3D animated host and instructor. Each lesson begins with a brief animated intro, which the student then reads their lesson afterwards, and then there is a chatbot that understands that lesson that engages with the student afterwards. The course will have about an hour of 1-2 minute videos in the end, and because they are an animated "professor" it is then possible to create other ethic versions, and other language versions easier than otherwise. And for the curious, that hour of final in-use video will be sourced out of somewhere around 8 hours of final video; these video AIs are fine and dandy for short content, but when working on longer form media the consistency issues grow to Godzilla sized and really become the most consistent issue: trying to keep the likenesses of the characters, and the environment from drifting over time.
