You must consider.......
Who you have used in your video and if you have their permission.
Provide evidence (letter, disclaimer form, email etc...)
How have you represented groups or individuals in your film?
Have you been fair? Have you avoided stereotyping?
Consider the OFCOM Broadcasting Codes
Which codes would you have to consider?
Did you have to change any of your ideas because you felt they may contravene one or several of the codes?
Choose 3 or 4 of the codes and explain that you are aware of the conditions of the codes and that you are satisfied that you are abiding by the rules.
