Welcome to the LIVE User-Generated High Dynamic Range Database

LIVE User-Generated High Dynamic Range Database (LIVE UGC-HDR)

Introduction

High Dynamic Range (HDR) videos are better capable of capturing real-world color and contrast information in comparison to Standard Dynamic Range (SDR) videos, making them more aesthetically pleasing. Traditionally, the production of HDR videos has been restricted to professional production houses that use sophisticated camera equipment. However, the recent introduction of HDR-capable smartphones to the market has opened up avenues for the creation of user-generated HDR videos.

The LIVE-UGC HDR database provides a collection of 10-bit HDR videos filmed by amateur iPhone users, and their corresponding professionally-graded versions for SDR displays. In the future, we envision that this database will be used for subjective studies and to build Video Quality Assessment (VQA) models.

Database Description

The database consists of 20 10-bit High Dynamic Range (HDR) source contents filmed on iPhones 12 and 13 by amateur users. All videos use the HLG encoding function and Rec. 2100 primaries. The database also includes graded Standard Dynamic Range (SDR) versions of the source contents that were created by a professional colorist using DaVinci Resolve to best replicate the appearance of the HDR videos in SDR.
