Beyonce- Countdown

In this shot they have used green screen and they’ve used it by layer many different thing of what Beyonce doing with the hands to create the effect that the shot goes with the narrative of the video as the song is called count down and when she has her hands up her fingers are used like in some of the picture she got 10 up or she got 4 and they have done that to make it look like she is counting down so that the shot goes with the narrative of the music video.

They have used green screen here by putting an orange background on top of the green screen and then layering it by putting 4 of Beyonce next to one another in different coloured outfits. This create an effect of her emotions as they have used quite bright colours which makes the audience feel that it is a happy video.

They have used green screen in this part they done it by putting a layer on top of the green screen and changing the background colour the adding another layer by putting Beyonce over the top of it wearing the same colour outfit to blend in with the background they used various different colour backgrounds as you can see in the picture below. This creates and effect of how she's feeling as they have used bright colours which makes the audience feel happy and make enjoyable to watch as it doesn't have dull colours in it.

Where they have used green screen here is by doing the layering again by where the put various shots of Beyonce up so that again the narrative can go with the story by the way that they have put the pictures in order of her counting down this make the audience wonder when they look at that shot and make them think why is she counting down what's going to happen when it get to 0.

Christina Perri- Jar of hearts

I think the reason that they have used green screen here and made it look as if she sitting on the stairs is to make the background go with the lyrics as the song is quite depressing and they've made her sit on the steps and have a dark dull background with the brick wall behind it to give it that effect and to make the audience feel sad and to go with the lyrics as its a depressing song.

They have used green screen here where they have got the Smokey background and the car next to her they have done this to make the audience feel that something is going on and that the place has been abandoned because of the way that the car has been smashed up and there's no-one about and they way the background on top of the green screen is that its foggy and dark.

They have used green screen here to make a very dark and depressing background as there are people fighting in the middle and they have also used to smoke to create an effect. They have used green screen here to create the effect of her emotions as you can tell that she feels angry and said by the background as the colours are dark and the smoke in the background.

They have used green screen in this shot because when she is singing she gets very loud and powerful and they have changed it to a very bright white background to make the audience feel that she seems very powerful when the background goes very bright, and they have used it to create her emotions and what she is feeling.

They’ve used green screen here to show that when she has killed the bad person they have changed the colour of the background and made it brighter to give that effect that you know that the bad person has going and its all good again.
