## 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.
