what factors must be taken into consideration when planning ?

There are a couple of key factors that we need to be aware of when planning our music video. :

1. Mood of the song
2. length of the song 
3. target audience
4. costumes
5. willingness of cast

The mood of the song effects the sort of setting we will need to find for a video.

We have to make sure we out as many things we can in to attract our target audience for example young cast for a young target audience. 

If we need to hire costumes we need to make sure we hire them for a long enough period.
