Rapid Crop-Uncrop function to preferred or automatic screen resolution

[FireLink]

For videos without black bands (ex. 1920x808).
The current "c" function is only circular.
It would be extremely useful to switch from the default to the preferred crop (ex. 16:9).

- An automatic mechanism capable of cutting even the black bands present in the original format would be just as useful, but I realize the intrinsic difficulty and anomalies that would occur during the night scenes and in the end credits (maybe you could use a special button from manually select during pause?)

Thanks for your kind attention.
