Yes, way easier and doesn’t sacrifice your field of view.

I use Paint.net usually and there are plugins people make that you can install. Does GIMP not have that?

Haven’t watched the video yet, but it makes a lot of sense that you could train an AI using already subtitled movies and their audio. There are times when official subtitles paraphrase the speech to make it easier to read quickly, so I wonder how that would work. There’s also just a lot of voice recognition everywhere nowadays, so maybe that’s all they need?
