The aim of this thesis was to investigate the user experience when watching different formats of video, specifically at the occurrence of a stall from the perspective of workload and stress. The three research questions narrowed the scope down to a comparison between linear and branched video and the presence, or absence, of a playback bar in the user interface (UI). The measurements used were Nasa-TLX, Short stress state questionnaire as well as thematic analysis of participants free text answers. No significant differences in workload or stress was found between branched and linear video, as well as between the presence and absence of a playback bar. However, due to high number of non-completion participants the results were of questionable validity. The thematic analysis of the free text answers indicated a contrary story to the results from the statistical analysis. Further investigation of the effects of workload and stress on stalls in video experience is therefore recommended. Finally, the thesis provide guidelines based on the lessons learned so to best address the remaining research questions.
