Abstract: This technical memorandum provides technical details for the video quality subjective experiment its4s3. This experiment includes 594 videos, each 4 seconds in duration. The experiment consists of six sessions, each portraying a different public safety scenario. The goals of this experiment are to demonstrate a wide range of quality responses from digital video cameras; to present video sequences suitable for first responder tasks; to begin to understand the video quality difference between video used as evidence and video used for situational awareness; and to collect data from a more representational sampling of people than is usually possible, by conducting the experiment at a large meeting venue. The its4s3 dataset is intended to train no-reference (NR) video quality metrics. The dataset is freely available for research and development purposes.

Keywords: video quality; subjective testing; public safety; camera capture; no reference (NR) metric
