I’m running a projector/ screen setup.
I watch both 16:9 and 2.35:1 content, with different zoom levels on the projector to maximize picture size for each aspect ratio.
This does of course mess up my subtitle pasition. A subtitle positioned on the bottom of a zoomed 2.35:1 results in a too high position when playing 16:9, and vice versa.
It’d be really nice if subtitle position could be pre defined for different aspect ratios.
