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 0.25, indicating it’s not very good at reacting to camera positions in the prompt. This suggests the generated images might not accurately reflect the intended camera angles.
• Shot Analysis: The model scored 0.565, which is good. This means it’s able to understand the scene in the prompt and translate it into a visually coherent image.
• Aesthetic Analysis: The model scored 0.17, which is not very good. This means the generated image’s aesthetic deviates significantly from the expected aesthetic based on the prompt.

Overall, the model shows promise in understanding the scene and shot composition, but needs improvement in accurately capturing the desired aesthetic.
