Meta AI video looks animated. Sora looks like someone actually filmed it. Bill Peebles built the Diffusion Transformer at Berkeley. It's the engine behind almost every AI video tool now. Runway uses it. Kling uses it. Meta uses it. Conference rejected his paper in 2023 for "lack of innovation." Now he runs Sora at OpenAI. Zuckerberg tried to get him back with a $100 million package. He said no. So if everyone uses his tech, why does Sora look different? Sora processes your whole video at once. Every frame sees every other frame. Objects don't vanish. Physics work. Lighting holds. Meta Vibes licenses outside models. Same foundation, different execution. They're all competing for realism. Meta's just not there yet. --- Ariadna Jacob is an AI video strategist helping creators master Sora and AI video creation. #soravideo #aivideocreation #contentcreator
