This graph illustrates the **estimated VMAF (Video Multimethod Assessment Fusion) ** scores over time, providing a detailed measure of perceived video quality that correlates well with human visual perception. Each orange box plot represents the distribution of eVMAF values during the corresponding time window. 

**Y-axis (eVMAF Score): **Represents the estimated VMAF value, ranging up to 100 - higher scores indicate better perceptual video quality. 

**Box plot components:**

- **Top whisker**: Maximum score
- **Top of box**: 75th percentile
- **Bottom of box**: 25th percentile
- **Bottom whisker**: Minimum score
