Yep. I watched their demo clips, and the “good” ones are full of errors, have lots of thematically incoherent content, and - this is the biggie - can’t be fixed.

Say you’re a 3D animator and build an animation with thousands of different assets and individual, alterable elements. Your editor comes to you and says, “This furry guy over here is looking in the wrong direction, he should be looking at the kangaroo king over there, but it looks like he’s just glaring at his own hand.”

So you just fix it. You go in, tweak the furry guy’s animation, and now he’s looking in the right direction.

Now say you made that animation with Sora. You have no manipulatable assets, just a set of generated frames that made the furry guy look in the wrong direction.

So you fire up Sora and try to fine-tune its instructions, and it generates a completely new animation that shares none of the elements of the previous one, and has all sorts of new, similarly unfixable errors.

If I use an AI assistant while coding, I can correct its coding errors. But you can’t just “correct” frames of video it has created. If you try, you’re looking at painstakingly hand-painting every frame where there’s an error. You’ll spend more time trying to fix an AI-generated animation that’s 90% good and 10% wrong than you will just doing the animation with 3D assets from scratch.
