Comment (by mkoch):
This is a workaround for removing the left vertical border (between x=249
and x=250) by applying a suitable luminance gradient to all pixels in the
x=229 to x=249 range.

geq=cb_expr='cb(X,Y)':cr_expr='cr(X,Y)':lum_expr='if(between(X,229,249),lum(X,Y)+lerp((X-229)/20,0,lum(249,Y)-lum(250,Y)),lum(X,Y))',format=rgb24
