Pitching concepts to my class and feedback

I presented my prezi to the class, explaining my idea about a music video.

Afterwards I got some really good feedback from the class on things they thought were good and on things that were issues and could be improved.
Everyone really liked the stylistic idea of the UV paint on people in the dark, someone also suggested that we could film this section in the studio as that would illuminate difficulties filming outside in the dark. People also liked the idea of a big open field and having the whole video and atmosphere very chilled and casual with a group of people watching the band perform, they agreed that MGMT Time To Pretend was a good song to create this effect as it was upbeat and different. However most of all they loved the bouncing balls idea as it is a very visually exciting element to have in a music video. However we then discussed how I could tie in the bouncing balls with the field performance as they wouldn't bounce if we had them in a field as we would need a hard surface. I then thought perhaps we could have them rolling down the field or a hill, or if the band performed on a small stage we could have them bouncing on the stage to the beat of the song.
I also received some useful constructive criticism which has helped me understand the practicality of some of the aspects of the video. Most people loved the bouncing balls and UV paint, however decided it would be too much to have both ideas, picking just one would make it easier to link the video and make it flow. The issue of a field was also raised as a lot of music videos are set in a natural environment eg field, woods etc, so I should consider the originality of this and make sure it is unique and interesting. If I wanted to use old vintage cars, eg the combi, it would be difficult and expensive to find and hire for the day. Another big issue with filming outside would be the weather, as it will be Autumn time when filming the weather will be unpredictable and if it rains and is dark it will not have the summer festival chilled vibe to it and will look odd. Another suggestion was to film three different strands in order to interchange between them to make the video more exciting and not just people in a field.
