Key steps and technology behind Sora video generation:
- Input Data Processing: Using a video compression network to compress images or videos into low-dimensional representations, simplifying processing while retaining rich visual data.
- Spatiotemporal Patch Generation: Sora breaks down the compressed data into spatiotemporal patches, capturing both spatial and temporal information for complex video content.
- Text-conditioned Diffusion Model: Sora uses text prompts to guide a Diffusion model that progressively denoises and generates visual content matching the text description.
