What are the obstacles for this technology?

There are several significant obstacles facing AI-generated video technology:

1. Computational requirements: Generating high-quality video requires substantial computing power, making it resource-intensive and potentially expensive.

2. Temporal coherence: Maintaining consistency across frames and longer sequences remains challenging, especially for complex scenes or movements.

3. Detail and realism: While quality has improved, achieving photorealistic details consistently, especially for human faces and complex textures, is still difficult.

4. Control and specificity: Allowing users to have precise control over generated content while maintaining quality and coherence is an ongoing challenge.
