In a stereoscopic project, grade files contain data for both the Left Eye and Right Eye.
In the Grade bin, each storage container can include Left Eye and Right Eye grading data. The thumbnail of the grade corresponds to the currently assigned eye. In the Grade view, the expanded Grade bin and its player demonstrate the same behaviour. See Using Grade Bins and Using the Expanded Grade Bin.
Disable Sync mode to apply data from a grade file to only the assigned eye: only the grade data for the current eye will be applied. When Sync mode is on, data from a grade file is applied to both eyes: if the grades are different for each eye, each grade is applied to the appropriate eye. See Synchronizing the Left and Right Eye.
