SSIMULACRA2 is an objective visual quality metric which gives a score of 0-100 of a video quality. The metric is based on the concept of MS-SSIM, and computed in a perceptually relevant color space, adding two other (asymmetric) error maps, and aggregating using two different norms. It is currently the most reputable objective visual quality metric for low-medium fidelity content.
Here's a rough guideline on how the metric corresponds to visual quality:
30 = Low quality. This corresponds to the p10 worst output of mozjpeg -quality 30.
50 = Medium quality. This corresponds to the average output of cjxl -q 40 or mozjpeg -quality 40, or the p10 output of cjxl -q 50 or mozjpeg -quality 60.
70 = High quality. This corresponds to the average output of cjxl -q 65 or mozjpeg -quality 70, p10 output of cjxl -q 75 or mozjpeg -quality 80.
90 = Very high quality. Likely impossible to distinguish from the original when viewed at 1:1 from a normal viewing distance. This corresponds to the average output of mozjpeg -quality 95 or the p10 output of cjxl -q
