A Study Of Subjective Video Quality At Various Frame Rates

This paper presents a new video database (BVI-HFR), which contains content with a variety of frame rates from 15Hz to 120Hz, that can be used to demonstrate the benefits and limitations of higher frame rates, as well as investigating the role that frame rates play from capture to delivery. A characterization of the video database using low-level descriptors is also provided, which establishes that it successfully spans a variety of scene types and motions, and compares well to existing video databases. Subjective evaluations performed on the video database, have demonstrated a significant relationship between frame rates and perceived quality, up to 120Hz. They also confirm that the relationship between frame rate and perceived quality is content dependent.
