360-degree videos offer an immersive experience which is hard to find in traditional videos. The entire scene is floating around the viewer, and a feeling of being there is common. However, something traditional videos have compared to 360-degree videos is control of the outcome. The filmmakers decide what they want to show and how they want to guide the viewer. The control is still an issue in 360-degree videos. In this thesis will the focus be on how a viewer can be attracted to an important part of a scene. This work is concentrated on methods and techniques in the post-production part of video production. The techniques are mainly video effects. The user tests involved 16 participants with different backgrounds including an expert in the field. The participants watched three 360-degree videos each with the same content, but with different techniques made in the post-production part to guide them. It was one video with graphical elements to guide them, one with light effects and one with colour effects. Interviews gave a deeper insight into the participant's experience and opinions on the three videos. The video effects affected the participants positively and negatively. The participants were mostly satisfied with effects consisting of graphical elements but not as much with colour. The users lost a bit of their freedom to explore a scene with the light effects, but they were useful when it came to guiding towards something. The participants did find the guiding lines and spotlight as the most suitable methods to attract attention; the spotlight was the most preferred of the two. The red circle effect and the warm/cold colour effect was the least preferred, the warm/cold colour effect as the least preferable. The effects helped to attract the viewer to a section of the video, and the user's got a better understanding of the concept. However, more research need to be done to draw attention towards something. A combination of elements like light effects and graphical element effects could improve the post-production part. Research in the future regarding the opportunity to combine techniques from an entire video production needs to be conducted for a significantly more effective way to attract attention to an important side of a scene, without the viewers losing their freedom of exploring, it includes both the post-production side but also methods to attract attention in a set.
