1. Green screen test analysis When i put the white background on the green screen video on imovie it created a dark black mark in the top right hand corner of the screen and there was a mark on the left hand side as well which you can see on the image on the right. As this ruined the effect of the illiusion of the green screen i tried to change the setting on imovie to try and fix it by using the brightness tools. However there was no change therefore i decided to test black background to see if there was any difference. When i put the black background on the green screen video on imovie it created a light white mark in the middle left hand side of the screen which you can see on the image on the right.When i ran the video with the two background in it the marks on the screen were obvious which made the video look unprofessional.As this ruined the effect i was tying to create of the illiusion of the green screen i tried to change the setting on imovie to try and fix it by using the video effects. However there was no change and after audience feedback i decided it would be best not to use the green screen in the music video. When i put the grey background on the green screen video on imovie it created a light white mark in the middle left hand side of the screen which you can see on the image on the right.When i ran the video with the all the backgrounds the marks on the screen were obvious which made the video look unprofessional.As this ruined the effect i was tying to create of the illiusion of the green screen i tried to change the setting on imovie to try and fix it. However there was no change so overall this proves that all the background colours will not work on the green screen

2. Green screen test analysis As you can see from the images above that the only colours that worked on the green screen for a background were blue and green with out having any dark/light marks to make the effect look unprofessional. After audience feedback as a group we decided to scarp the green screen idea and start again by planning a story board for the same song. As one of us already had an concept we could do we started that.
