My role for iMovie macOS & iOS was designing the UI/UX. I have been apart of a few releases for both products. Some key features that I helped work on are updating and designing a new look for the apps & rethinking key user workflows.
macOS - NEW LOOK
Following the release of iOS 7 and OS X Mavericks, the user interface of Apple apps changed drastically. Skeuomorphism is no longer the trend and apps now have a flatter design. The team had to update iMovie with a new flatter and modern look.
The team also noticed iMovie was getting more difficult to get a project started and how media was being organized. It was pushing a pro workflow on to novice users making it hard for some to understand.
iOS - NEW LOOK
For iMovie iOS, the team was tasked to update the visuals - removing overlays on thumbnails and showing only the content. We also redesigned the inspector in the timeline view to where new features and tools can be added with ease.
