Conclusion

The results of the analysis show that the generative AI model performed well in understanding the scene and camera position, but struggled with the aesthetic aspect. Here’s a breakdown:

• Camera Position: The model scored 0.36, which is below the “good” range of 0.5 to 0.75. This indicates that the model didn’t fully capture the intended camera position described in the prompt.
• Shot Analysis: The model scored 0.53, which falls within the “good” range. This suggests that the model was able to understand the scene described in the prompt and create a shot that aligns with it.
• Aesthetic Analysis: The model scored 0.22, which is significantly lower than the “very good” range of -0.2 to 0.1. This indicates that the generated image’s aesthetic deviated significantly from the expected aesthetic described in the prompt.

Overall: While the model demonstrated good understanding of the scene and shot composition, it struggled to achieve the desired aesthetic. This suggests that the model might need further training to better understand and translate aesthetic preferences into visual outputs.
