Chroma key is a special effect and post-production technique for combining two images/videos or more together. This technique is heavily used in many different fields of media such as news casting, film, television, music videos, video games. They are used to remove a background from the subject of a photo or video. They are used for performance in different location.
Chroma keying can be done with backgrounds of any colour but I recommend using the colour green which is the most common colour for Chroma keying. We use the colour green because it is a less common clothing colour, meaning it's less likely to make part of your body to disappear with the green screen. Wearing green clothing with green screen behind won't be exactly a good idea. Green is also used often because it's easiest for most modern cameras to pick up, make it easier for the video-editor. White is a bad colour to use as it's common clothing and eyes. Same go to the colour black, which include hair. Both of these colours play a strong role in lighting and shadowing, which is also another reason for you to avoid these colours. Red is another bad colour because it's seen in our lips and mouth. To select a good colour aside from green and blue, pick one colour that's not going to be found on anything else in the shot.
Green screen is used to add effect to videos. It’s used to focus on the performance of Artists. Artists don’t want their music videos to look boring, they want the music video to catch the audience's attention. Artists may use green screen and effects for their music videos to create a sense of hyper-reality. As hyper-reality music videos can appeal to their target audience and make their music video successful. Most hyper-reality music videos are usually unusual and creative. It's also can be original and unique. This style of music video usually help the artist create bigger fan-base and generate revenue. It also allow to portray these artists as creative, artistic, dynamic, original or weird etc. Green screen could be use for sense of hyper-reality, to reflect the lyric, to focus on the artist/performance or to represent emotions etc.

We use green screen because it's cheaper and it allow us to be creative and unique. It also allow us to get to the location we can't normally get to. VFX have their own award as they are now conventional in music videos. We should use filters to blend the subject into the background so it would look realistic and not fake. Usually when green screen is over-used, it doesn't have a purpose.
David Hasselhoff - Hooked on a Feeling is an good example of an bad chroma key. You could tell it was bad, the subject did not blend with the background at all, there was some scene that were cringe and laughable as if it was a comedy film. At 0:51, when he catches a cube you could clearly see fake and unconvincing it was, then the next scene he started flying as if he got some supernatural power.
There was another scene where he was standing on top of a moving motorbike like it was nothing, droving past a monster and started to fly. At 1:56, the way he was flying was not believable at all. It look like he just bending over with his arms out. The overall of this music video was obviously not convincing, to make the video better they would have to use filters to blend the subject into the background to make it more convincing.
However, bad use of green screen can make the video go viral as it will be enjoyable to watch. The video has over 12 million views, 34 thousands likes and only 3 thousands dislikes, this show many people have enjoyed watching this music video. This generated a lot of revenue.
Labrinth - Earthquake ft. Tinie Tempah is an good example of an good chroma key. This music video has used green screen to make the artist the centre of attention. The green screen helps create a sense of hyper-reality. Music videos with good chroma key bring power to the beat which will engages with the audience more. When he says "I predict an earthquake up in here", the room/screen shakes along with visual sound waves with a touch of his hands or feet, the green screen has given the artist the control of his music as he has control of everything he does in this music video. This created link between the lyric and visuals and also music and visuals.
The green screen can make the audience think they are in another world with the artist. The music video has over 79 million views, 350 thousand likes and 10 thousand dislikes. This also show many viewers were entertained by this video and they decided share to their friends. As it was hyper-reality music videos, there's likely a chance that the music video will be successful or viral or both. Most hyper-reality music videos are usually unusual and creative like this one. This style of music video usually help the artist create bigger fan-base and generate revenue. This has helped them generate revenue.
Chroma Key Guide
Chroma Key Guide
This is a footage I kept from last year when I did a practice music video. Once you have filmed the footage with the green screen and you got what you wanted, you can now begin to edit your video which would be entering post-production. In order to remove the background (green screen) from the subject of the video, you'll need editing software such as Final Cut Pro, Premiere Pro, After Effects, Sony Vegas etc. So you can get to use this Chroma key plugin which could be called different depending on what software you use, for example, 'Chroma Keyer, Keylight 1.4, Ultra Key' etc. On Final Cut Pro, it's called 'Keyer'.
After importing your footage and placing it on the timeline, you'll need to go to the Effects library and search for Keyer. Once you found Keyer, you'll need to apply the effect to the footage. After you've applied it, you will noticed that the green screen have been removed and the background is now black. This mean you can now look for clips online that could be used as a background or you can record that footage yourself as well. Once you've found the footage you want to use as a background, you have to import it to Final Cut Pro and drag and place it under the footage which background you already removed.
This is the final outcome, I decided to use a white backdrop as my background because it's the perfect foundation for showcasing your creativity. It focus the viewer's attention on the artist as it will prevent visual distractions. We can use the space for other things such as visual effects or text etc. I also replace the original audio that came with the footage and swapped it with the soundtrack as it's much better sound quality.
