Chroma Key can be described as a a digital technique by which a block of a particular colour (which is often blue or green) in a film or music video. However this image can be replaced by another colour or image, enabling, for example, a weather forecaster to appear against a background of a computer-generated weather map or an artist to be on the moon in their music video.
The first step of using chroma key is to make sure that you have a green screen to use. Without the green screen it will be impossible to use chroma key.
The next step is making sure that the subject is framed correct. this is important because depending on what kind of environment you would like to input your subject into , both shot type and framing need to be correct for example a mid shot or long shot are ideal for showing of bigger environment that you may potentially choose.
After this you will need to make sure that both the subject and the green screen are well lit. This is done because if the green screen is not being lit correctly it will affect the quality of your music video.The aim is to get rid of all the the shadows that will show up on the green screen, to this you will have to re adjust the lighting around the subject until the shadows are gone.
Now that you have recorded your artist performing the song make sure you record takes in different angles and shot types. After you've done this now you can begin to work with chroma key.
The reason why chroma key is used in music videos is to create imagery that won't be accessible to real life for example the artist here Action Bronson has used chroma key to show himself flying into space. This can be done to illustrate one of the lyrics in the song, or even yet illustrate the feeling of the music. This also allows the artist to be more imaginative.
Another reason why artist may use chroma key in their music videos is to portray a certain image better than a real life location. For example rapper "Yung Lean" claim to fame is for his music video "Hurt". In this video the artist is seen performing using chroma key how it has been edited to look strange and outlandish this is what drove the internet to react to it , cause the video to go viral. This was all possible because Yung Lean was able to put together all the images he wanted (no matter how random) to create a hypereality which of course plays into his image of being strange and outlandish.
On the other hand a more effective use of chroma key can be found in the visuals for will.i.am - T.H.E. in this music video there is a perfect blend of real life locations and locations that have need chroma key to appear as a result the artist looks like he is futuristic , however the budget for this video would surpass the budget for the previous examples., as result its puts the artist in a hypereality world however it is believable. Nowadays it is evident that videos are reliant on the use of chroma key. this is because it is a easier way of spacing a artist image, for example people how make popular music such as will.i.am. However i feel like indie artist may use chroma key to show how artist and strange they are and even to the extent it might be even mocking the commercial use of chroma key.
in conclusion the effectiveness of chroma key is dependent on what kind of image the artist is trying to portray. Whether it be a futuristic ranger or whether it being king of their own world chroma key is used to make it visually possible, because if we didn't use chroma key in music videos i feel it would cripple certain genres music videos from looks identical.
