would seem to imply that presence of real border is unimportant. (dont want an argument here).
RoboCrop crops to the outermost border.

Slowish, Would need to use ScriptClip().
Could use RT_Stats RT_AverageLuma(x=X,y=0,w=1,H=0) to scan vertical colums at X. (inside Scriptclip script).
RT_AverageLuma(n=current_frame) # is the default.
Not too difficult to code that really, go on, have a go
EDIT: Would of course also need GSCript.
