How does the video recover to the default settings?

[xuboleo]

Once i push the button Q\E\T\U\A\D\G\J\Z\C\V\N, the video dould never be clear displayed. Even i pushed the recover bottons, which did little to recover the video. Thanks for helping!

Do you mean that if you, e.g., increase brightness, your video remains "very bright" forever? Can you increase, but not decrease...? I think I need more information to understand your problem.

Does your video looks normal when you start playing (without pushing those buttons)? Have you ever reset to default KMP? What video filter are you using?

Thanks for your concern!
I can increase, decrease and reset the brightness, color, contrast, etc.
but it helps little to the video, i mean once i changed the settings, it cannot return back to nomal-the perfect video.

:confused: I understand that you push the keys to change colour, contrast, etc. but it has not the desired effect on the video you are watching...

So, for example, you want to change brightness: What happens if you push "E"? And when you push "U"?

In my case, only one of the keys work to increase brightness, the one which does it depends on the video filter or other video settings. What video filter-settings are you using?

but it helps little to the video, i mean once i changed the settings, it cannot return back to nomal-the perfect video.

:confused: :confused: Return back to normal-the perfect video? So, when you start whatching the video, do you start watching a "perfect" video? And, when you change colour controls, does it become a "non-perfect" video?

Sorry, I still can't understand your problem, so I can't reproduce it. So, if you could give a better explanation, some example...

I used "KMP Built-In Filter".
Let me try my best to give you an example: Suppose the default state after installation is A, which i said as the perfect video. But if i push the increasing/decreasing brightness button T/U, the video's state become B, which cannot return back to state A whatever i do. There always some defects when i adjust the video, the color, the bightness, the contrast, or the caption, etc. And i cannot find the button of returning back to default settings.
Again, thanks for attention!

Thank you, this example has made me understand your problem better.

I think you already know the button to reset KMPlayer to default settings: it's in Preferences window, on the lower left corner as "Reset current preset". Does your video return to "state A" after resetting to default?

I think those problems deal with the video config, or the capabilities of the video card. Someone in this forum has been able to see the black bars in their videos in blue, after changing some settings...

I would like to know what video renderer are you using: right click on the video window, then go to "Video (advanced)" option, and then select "Video renderer" in the sub-menu. What of these video renderers have you selected?

I have experienced some differences when using each one. And concerning to the colour controls, the behaviour is different depending on the one I have chosen.

Try changing the video renderer and tell me if you can experience some changes in the visualization, and if you can reach the perfect video.
