+This is an **unofficial** copy of the videos in the *LSVQ dataset (Ying et al, CVPR, 2021)*, the largest dataset available for Non-reference Video Quality Assessment (NR-VQA); this is to facilitate research studies on this dataset given that we have received several reports that the original links of the dataset is not available anymore.
+
+*See [FAST-VQA](https://github.com/VQAssessment/FAST-VQA-and-FasterVQA) (Wu et al, ECCV, 2022) or [DOVER](https://github.com/VQAssessment/DOVER) (Wu et al, ICCV, 2023) repo on its converted labels (i.e. quality scores for videos).*
+
+The file links to the labels in either of the repositories above are as follows:

+```
+--- examplar_data_labels
+--- --- train_labels.txt (this is the training set labels of LSVQ)
+--- --- LSVQ
+--- --- --- labels_test.txt (this is the LSVQ_test test subset)
+--- --- --- labels_1080p.txt (this is the LSVQ_1080p test subset)
