The editing platform I have used for all the film openings is iMovie. The program is quite useful and easy to manage for what I need it for.
The process of editing does not take me long to complete because I already have a solid idea of what I want once the shots and music have been taken and recorded. As we filmed three different days, I started editing what I could after the first day and went on from there. The music had already been recorded but was added at the end.
Throughout the entire edition process, I would message my partner if I was unsure of which shot we wanted to use and also to get her approval to how it was coming along. It was quite a seamless process as we work well together.
