Fade out/in: These effects were used several times throughout our music video particularly at the end and the beginning. Fade white was used at the beginning of the music video to show Katy Perry was remising about the night before. Whereas the fade to black was used at the end to highlight the video had come to an end.
Speed: In terms of the speed of our music video we used several tools to alter it. Including slow motion, reversing the speed and speeding it up. We featured these effects in different aspects of the music video to emphasise particular scenes and shots. For example, towards the end of the music video we reversed a number of the clips used earlier on. This was done to give some sense of a build up towards the final shots which showed the final ending to the story.
Change Colour: To compliment the theme of the video we changed the colour of some of the clips to make them look more colourful and added a solarize effect. As a group we felt this would fit well with the image of Katy Perry and overall portrayal of her and the music video. The screen shots below show various examples of it being used.
