I think what's most important would be the theme/story you want your mv to convey.
Like for example if it's about friendship, then all your shots chosen would be based on that. Your song choice and how you cut or time your shots would all be according to the mood and story you want your audience to experience.
Next, the good thing about music videos is that it doesn't have to make sense 100% of the time. So it's good to experiment what works and what doesn't even if it's not exactly logical.
