Tips

  • Sora excels at cinematic, photorealistic content. It handles lighting, depth of field, and natural motion well.
  • Use remix for style transfer, seasonal changes, or transforming the mood of existing footage.
  • Pro tier is only worth it for hero shots. The standard model is usually sufficient.
  • Combine with image generation — create a reference frame with Flux Pro or Nano Banana, then animate with Sora.
