This work describes a new blind video quality assessment (BVQA) method based on a hybrid training methodology, BVQM-HT, which was submitted to the WACV 2023 HDR Video Quality Measurement Grand Challenge. This quality metric was first trained on a large amount of training material from a diverse video database, BVI-DVC, and the training data were labelled using an existing perceptual quality metric, VMAF. An additional shallow CNN is then employed for temporal pooling, optimised using a small HDR subjective video database, provided by the Challenge. This no-reference quality assessment method was then evaluated on the Challenge private test set, and achieved superior correlation performance with perceptual quality over other submitted BVQA methods, with a SROCC value of 0.749.
