Animals
Animals could have been something which we could not control if they had been in our filming.
Children
Children were using the park and running around this was something that we could not control.
Lighting
Lighting could have a huge effect on the colour of filming to bright would make the music video very unclear, to dark we will not be able to see the filming.
Weather
The weather was very bright so the filming was hard to do; weather is something we could not control.
Mud
The park was very muddy so it was hard to film were we wanted to film but this is something we could not control.
