Conclusion

The results show that the generative AI model performed well in terms of camera position and shot analysis, but struggled with aesthetic analysis.

Here’s a breakdown:

• Camera Position: The model scored 0.1, which is considered very bad. This means there’s a significant difference between the camera position specified in the prompt and the camera position in the generated image.
• Shot Analysis: The model scored 0.48, which is considered good. This indicates that the model was able to understand the scene in the prompt and create a shot that aligns with it, but there’s room for improvement.
• Aesthetic Analysis: The model scored 0.09, which is considered very good. This means the generated image’s aesthetic closely matches the expected aesthetic.

Overall, the model seems to be better at understanding the scene and creating a shot that aligns with the prompt, but it struggles with accurately capturing the intended camera position. The model’s ability to create aesthetically pleasing images is a positive aspect.
