Music videos nowadays commonly have CGI and VFX which creates a stunning and nostalgic feel when watching them as a viewer. It does this as CGI can do more than it ever has before, even if the budget is all over the place. The opportunities for Visual Effects in post production have been greater than they have ever been. One way they use Visual Effects is to test and try ideas to see if they would work as they can be more creative of what they can do. They can often deliver some crazy, cool effects in the final piece. Another technique is speaking to an animator or director who can share ideas as they know what things need to be added and how things should be. You could use chroma keying (green/blue screens) as it's easier to bring in certain clips together as it's all separated and it allows more freedom into what you can do with a screen. FX artists can add a look to music videos in post production giving it glows, contrast and colour effects, a grungy film feel, or a sharp digital look or even painted look. By using storyboards it makes it easier to compose your ideas and create a story which will flow easily. By getting a face in a video will promote a person as much as the song and at the forefront most of the time so therefore you don't need to be tempted to create a visual effect masterpiece that doesn't involve the person!
