What commenters say

  • The release of Sora is seen as a marketing promotion rather than a significant improvement in AI video generation capabilities.
  • Open-source video models, such as Hunyuan, are considered to be more capable and cost-effective than Sora.
  • The current state of AI video generation is limited by technical issues such as object permanence, temporal stability, and physics comprehension.
  • The pricing and limitations of Sora, including watermarking and video length restrictions, are seen as restrictive and potentially uncompetitive.
  • Some commenters believe that AI video generation is not yet ready for industry applications such as Hollywood, while others see potential uses in advertising and social media.
  • The need for human-guided edits and the low percentage of usable output are major challenges for AI video generation startups.
  • Incorporating physical constraints, such as Hamiltonian constraints, could potentially improve the quality of AI-generated videos, but this is seen as a difficult task.
  • The quality of AI-generated videos is hindered by motion artifacts, particularly in scenes involving fluid or dynamic movements.
