I have already made a post about this (Contour ShuttleXpress Preset) but the diagram needed updated and the download link no longer worked.
The Contour Shuttle Xpress is a neat little peripheral that lets you assign five buttons and two dials to anything you want for any program.
You can buy a Shuttle here: Amazon.com here: Shuttle Xpress - Multimedia Controller for Editors or here: https://www.bhphotovideo.com/c/product/697104-REG
There is no preset for Shotcut, but don’t worry, you can download one with the link below! Here is a diagram showing what actions my preset assigns to each button.
Of course you can change the buttons to do whatever you want with the configuration software (which you can download here: Drivers – Download Software for Contour Design Products scroll down the page)
Just download this file, and import it into the Shuttle Configuration software
I hope this helps someone! Happy editing!
