OpenAI's video generation tool Sora has garnered significant attention since its launch, but where it draws its expertise from has remained a mystery. Now, a corner of that mystery seems to be revealed: Sora's training data likely contains a large amount of game live streams and tutorial videos from Twitch! Sora acts like a skilled 'master of imitation', capable of generating videos of up to 20 seconds long just from text prompts or images, and can handle various aspect ratios and resolutions. In February of this year, OpenAI first publicly introduced Sora.
