ProCutX is an iPad app that we have recently discovered that is compatible with Final Cut Pro. It's free on the App Store and we're currently learning how we can implement it as a regular piece of software whilst editing.
The app communicates over WiFi with our iMac/MacBook Pro and has multiple hotkeys which make editing a smoother, quicker process, improving the quality and speed of our edits. Being the tech nerds 8-) that we are, we are always on the lookout for bits of software we can implement in to our workflow.
This will also greatly benefit us onsite at events and conferences. The MacBook screens, being much smaller than iMac screens, are sometimes difficult to access all of the hotkey functions, but now we will have a dedicated second screen for quick access to these functions.
