Abstract

High frame rates are currently under discussion in the broadcasting industry as part of ultra-high definition standards. Previous subjective tests showed that a substantial improvement in video quality is possible with high frame rates, and there is wide agreement that 100 frames per second (fps) will be a suitable high frame rate for television in Europe. However, details of the relative importance the two most significant artefacts affected by the frame rate, motion blur and strobing, are not well understood. These complementary artefacts can be controlled with the camera exposure time, but cannot be simultaneously optimised. We conducted subjective tests at 100fps, measuring the visibility of motion blur during tracked motion, and strobing during untracked motion, with different exposure times. Both artefacts were rated in the same test, allowing the results to be directly compared. Hence we are able to make recommendations on optimising overall motion quality in a 100 fps system.
