Style

There are several concepts of style in music video and the styles in music video are all about relating and engaging with our environment. Expression through music video is greatly accented through the use of bodily movement, technology used and the story of the music video.
Music video as a categorical tool is used to put music into genres. This is used to answer questions about the period of time used in the music video and how authentic the music video is. As an evaluative concept, style is a brand of quality that distinguishes high quality videos from the low quality videos. The offensive and the non-offensive, etc.
Style can be purchased in the world of the music video, this means that style is the latest fashion or trend in the market. Whatever is in or out at the time music videos will try and capitalize on these trends to make the most successful music videos possible. (pg. 92,93)

Three-point editing

Three-point editing is a process used to insert media into a track in your editing software. The first two points that would be set are the in and out points of the clip in the viewer. The next step is to set the in and out points in the sequence where you want the clip to appear. One would then choose the tracks in the timeline where they want to clip to appear, then dragging the clip into the timeline.
To me the significance of three-point editing is an easy way to make sure that you get exactly what you want in your video. Setting the in and out points lets an editor get exactly what he/she wants into their video with ease. You can cut exactly what you want in our out and just drag it where you want it to be in your timeline, it's very simple.
