I then wrote a research script and arranged with journalists, picture producers and editors to do some user testing. This involved anther prototype I built using Axure. We tested with around 12 participants, some in the newsroom and some remotely from other newsrooms around the UK.
The research gave us valuable insights that we wouldn't have found without putting it infront of users, such as the users wanting to be able to drag the entire sub-clip area once it had been defined. We also disproved some of our assumptions, such as the user being able to see the duration of their clip. We thought this was important but it didn't seem to be.
