The examples are most certainly cherry-picked. But the problem is there are 50 of them. And even if you gave me 24 hour full access to SVD1.1/Pika/Runway (anything out there that I can use), I won't be able to get 5 examples that match these in quality (~temporal consistency/motions/prompt following) and more importantly in the length. Maybe I am overly optimistic, but this seems too good.
Credit to OpenAI for including some videos with failures (extra limbs, etc.). I also wonder how closely any of these videos might match one from the training set. Maybe they chose prompts that lined up pretty closely with a few videos that were already in there.
