How about a matte box filter that has an aspect ratio "window", an Aspect Ratio Imaging Device or ARID for short, etched into its surface. Or an overlay with the same "windowing" feature?
The ARID would be like a window-within-a-window, in that what lies within the window would be the aspect ratio that you would desire to have. While what lies outside of the window, would be the specific aspect ratio of that filter's window, i.e. 4:3, as well as the thickness of the overlay or filter.
The ARID would then be editted out in post.
At the risk of revealing my ignorance, the ARID matte box filter could not only act as a lens protector but also as a shim-like device that could help eliminate any slippage, caused by a poorly fitted filter, during panning, tilting, or other camera movements, thus reducing any "visual aberations" from shooting through an angled filter.
The ARID could come in a handful of favorite aspect ratios and thicknesses at first, and could grow to include more in the future if the tool proved practical or beneficial. Any comments, suggestions, or otherwise polite feedback would be appreciated. Thank you.
