If the following three conditions are met:
1. The user has their system configured to use a SYNC | HD
as the loop sync master.
2. The SYNC | HD is locked to an external video reference.
3. The user imports a video whose frame rate does not match
the speed of the external video reference from step 2.
Then display a warning that effectively says "The frame rate of the video you have imported does not match the speed of your selected video reference. What would you like to do?" The two clickable buttons are "Ignore" and "Switch the SYNC | HD to internal sync".
