Using other people's work in your film
When creating a video, you may want to add some extra footage or images into your final piece that you were unable to shoot yourself. However, you have got to be aware of who owns the materials and you'll need to check the copyright on them before you use them. There are some places where you can access copyright free material, please see the links below for a few examples.
The Creative Commons are an organisation that allows people to add copyright-licences to their work. Allowing the creators to clearly define what which rights they reserve and which they waive for the benefit of the people who are wanting to use it in their work.
