Remember that 'air head' video made with Sora? Turns out it used a ton of rotoscoping and manual VFX.
A 'head' would pop back on, and the balloon colors would keep changing from generation to generation. TL;DR researchers and developers of generative AI tools really need to prioritize consistency and control.
"While all the imagery was generated in SORA, the balloon still required a lot of post-work. In addition to isolating the balloon so it could be re-coloured, it would sometimes have a face on Sonny, as if his face was drawn on with a marker, and this would be removed in After Effects. Similar other artifacts were often removed."
