BATMAN "Sharpen" When needed?

Sorry for a newbie question.

When are you supposed to use "Sharpen" command in BATMAN, and which level: 1, 2, or 3

And what negative effect will you get from using "Sharpen"?

Thank you for all input.

Hi chris, please read the BatMan Help which you can invoke with "?".
You never "need" sharpening, it's just an optional "special command".

Thank you BobbyQ

I know it is a special command but I would like to know if you often use it to sharpen the picture and what the negative effect of using it to the picture.

Does a normal DVD ripped video need to use this command?

Thank you

You never "need" sharpening. DVDRips look fine without.
This was designed for people who like very sharp pictures, and for unsharp material such as bad vhs rips.
Just try it out and you'll see.

Thanks a lot, BobbyQ.
