What is "black bar detection" about? (1 Viewer)

[Klez]

Hello,

First: Thanks for this great plugin. It works nicely for me. But to tune up some settings i would like to understand the exact functionality of IFC.

1.) Can someone explain me what the black bar detection is about and whats the advantage of cropping the bars?
2.) Whats the difference of "single black bar" and "double black bar"? (except the wording )
3.) Why is the default setting for 16:9 "stretch" if my screen has a 16:9 resolution? It should be native or?

Maybe someone is so nice to answer my "stupid" questions. Thanks!

Is there no-one who can answer my questions?

Black bars is black areas in video when your broadcaster provides 16:9 material in 4:3 frames. In this case black bars are parts of frames and we should detect for it if we want to see full screen 16:9
2 if i understand correctly it is a detection method, only by one black area for exaple upper or by two of them.
3 cant comment, im changing it to normal on my setup.
