Planning Editing
The most common form of editing for a music promo is fast cut montage, rendering many of the images impossible to grasp on first viewing thus ensuring multiple viewing.
There are videos that do use slow pace and gentler transition to establish the mood.
This is particularly apparent for the work of many female solo artists with a broad audience appeal, such as Dido.
Often enhancing the editing are digital effects which play with the original image to offer different kinds of pleasure to the audience. This might take the form of split screen, colourisation and of course block buster film style CGI.

This Radiohead music video is an example of an unusual editing method because the whole song is filmed in one take, this is not following common codes and conventions of most music videos however it works because there is a lot happening in the video and it follows a storyline.
