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 0.35, which is below the “good” range of 0.5 to 0.75. This suggests that the model didn’t fully capture the intended camera positions described in the prompt.
• Shot Analysis: The model scored 0.455, also below the “good” range. This indicates that the model didn’t fully understand the scene described in the prompt and didn’t create the expected shot composition.
• Aesthetic Analysis: The model scored 0.17, which is within the “very good” range of -0.2 to 0.1. This means the generated image’s aesthetic closely matched the expected aesthetic described in the prompt.

Overall, the model seems to be better at understanding the desired aesthetic than the camera positions and shot composition. This suggests that the model might need further training to improve its ability to interpret and translate camera positions and shot descriptions into visual representations.
