Conclusion
The generative AI model performed well in terms of understanding the scene and camera position, but struggled with the aesthetic aspect. Here’s a breakdown:
- Camera Position: The model scored 0.3, which is considered below average. This suggests that the model didn’t accurately capture the intended camera position described in the prompt.
- Shot Analysis: The model scored 0.62, which is considered good. This indicates that the model was able to understand the scene and create a shot that was relatively close to what was described in the prompt.
- Aesthetic Analysis: The model scored 0.06, which is considered very good. This means that the generated image’s aesthetic was very close to the expected aesthetic.
Overall, the model shows promise in understanding scene descriptions and achieving a desired aesthetic, but needs improvement in accurately capturing camera positions.
