Systematic Assessment of the Video Recording Position for User-generated Event Videos
Stefan P. Wilk, Wolfgang Effelsberg · 2014
The increasing capabilities of mobile handhelds to record high definition videos enable us to share moments with friends and the public. In large-scale events such as concerts, the manifold of potential views recorded by the audience allows to watch an event from different perspectives. In this work, we elaborate on the effects of different recording positions on quality and show that especially with retail smart phone camera sensors the quality differs as the position changes. This is a first systematic approach to describe why user-generated video sequences differ in terms of quality depending on changing recording positions. To achieve a sound understanding, we conduct a large-scale systematic subjective study using crowdsourcing, inspecting the effect of distance and orientation of a recorder in relation to the event taking place. Our results indicate an effect of the recording position on the perceived quality of a video.
