在Windows平台上观看您喜欢的电影或视频时，VLC 多媒体播放器(VLC multimedia player)是推荐的选择。这是一个很好的程序，但已知偶尔会导致不良问题 - 特别是当程序的默认设置更多地关注兼容性而不是质量时。例如，有时图像中的黑色等级可能无法正确显示，并且可能显示为灰色。图像褪色或呈乳白色，如下图所示。
对于播放电影或视频等任何类型的多媒体文件，媒体播放器比其他任何东西都更重要。这个开源媒体播放器功能非常强大，易于使用，可以根据用户要求轻松定制。VLC令人印象深刻的功能可播放大多数多媒体文件，包括流媒体协议并在所有平台上运行。此外，VLC播放器支持大多数视频文件格式，无需额外的媒体编解码器。此功能丰富的媒体播放器可供免费下载。
显然，一些VLC媒体播放器用户报告了在VLC上播放视频的一些问题。用户看到失真的视频，并且在视频播放期间可能会随机观察到奇怪的颜色。视频无法呈现正确的颜色，并且颜色似乎褪色。问题的根本原因可能是由于图形驱动程序的问题或无法正确解码视频的编解码器的问题。
如果您面临 VLC 褪色(VLC)和颜色失真的问题，那么只需进行一些小的调整，您就可以恢复VLC播放器的正常状态。这里有一些解决问题的建议。
VLC 褪色(VLC)和颜色失真问题
乍一看，您可能很难注意到变化，但是，如果您在不同的视频播放器中播放相同的视频，例如在两个不同的屏幕上播放 VLC Media Player(VLC Media Player)和Windows Media Player，并比较图像，差异应该是很容易辨别。
因此，如果您发现颜色有任何差异，尤其是黑色级别，请尝试根据您的要求调整系统配置。
1]使用NVIDIA设置调整(Adjust)视频颜色
右键单击(Right-click)计算机系统的桌面并从中选择NVIDIA 控制面板(NVIDIA Control Panel)。如果您找不到/找到该条目，请按Windows 键(Windows-key)，键入NVIDIA 控制面板(NVIDIA Control Panel)，然后从搜索结果中选择选项。
在那里，在“选择任务(Select a Task)”部分下，您会看到 3 个标题 -
- 3D 设置
- 展示
- 视频。
选择“视频”并转到“调整视频颜色设置”。
在这里，启用“使用 NVIDIA 设置”选项并切换到“高级(Advanced)”选项卡。
现在，在 Dynamic Range 菜单中选择Full (0-255)而不是Limited (16-235) 。
单击应用进行更改。
完成后，您会注意到显示的变化。(Once done, you will notice the change in the display.)
2]更改视频卡设置
该问题主要发生在VLC上的视频问题上，在(VLC)Nvidia卡上选择了硬件YUV > RGB转换。默认情况下， VLC以(VLC)RGB 16到 235 而不是 0,255播放YUV MKV内容的所有视频。那就是 VLC播放电视格式的视频，从RGB 16到 235。禁用将每一帧从电视格式YUV转换为RGB的功能。这是针对YUV(YUV)内容的客户端修复。
打开 VLC 媒体播放器。
转到工具(Tool)并从下拉菜单中单击首选项。(Preference)
点击视频。(Video.)
在视频设置(Video Settings)中，取消勾选Use hardware YUV> RGB conversions.
启用加速视频输出（叠加）。(Accelerated video output (Overlay).)
启用窗口装饰(Window decorations)。
保存(Save)以应用更改。
重新启动 VLC 播放器。
3]将OpenGL设置(Set OpenGL)为输出(Output)视频方法
转到工具(Tool)并从下拉菜单中单击首选项。(Preference)
点击视频。
找到输出(Output)视频方法并从下拉列表中选择OpenGL 视频输出。(OpenGL video output)
保存(Save)以应用更改。
重新启动 VLC 播放器。
如果这没有帮助，请从菜单中选择“工具”，导航到“设置”并选择“视频”。然后您可以按照播放性能降低的顺序尝试以下操作：
- 切换到 DirectX (DirectDraw)
- 如果这不起作用，请切换到Windows GDI视频输出并查看。
我希望有帮助。

VLC washed out colors & color distortion problem
Whеn it comes to vіewing your favorite mоvies or videos on Windows platform, VLC multimedia player is the recommended choice. It’s a good program but is known to cause undesirable problems occasionally -especially, when the program’s default settings focus more on compatibility than quality. For instance, sometimes the black levels in images may not be displayed correctly and may appear as gray. The image is washed-out or milky, like the ones seen below.
The media player is more important than anything else for playing any kind of multimedia files like movies or videos. This open source media player is extremely powerful, easy to use and can be customized according to user requirements hasslefree. VLC’s extremely impressive features play most of the multimedia files including streaming protocols and runs on all the platforms. Moreover, the VLC player supports most of the video file formats without the need of additional media codecs. This feature enriched media player is available to download for free.
Apparently, some VLC media player users have reported few issues on playing video on VLC. The users see a distorted video and may observe a strange color at random intervals during video playback. The video fails in rendering a proper color and colors appear to wash out. The root cause of the problem may be due to the issue with graphics drivers or an issue with a codec that fails in the proper decoding of a video.
If you are facing VLC washed out colors & color distortion problems, then with few minor tweaks, you can restore the normalcy of VLC player. Here are a few suggestions to fix the issue.
VLC washed out colors & color distortion problem
At first sight, it might be difficult for you to notice the change, however, if you play the same video in different video players, say VLC Media Player and Windows Media Player on two different screens, and compare the images, the difference should be readily discerned.
So, if you notice any difference in colors, particularly black levels, try adjusting the system’s configuration to your requirements.
1] Adjust video color with NVIDIA settings
Right-click on the desktop of the computer system and select NVIDIA Control Panel from it. If you cannot find/locate the entry, press the Windows-key, type NVIDIA Control Panel, and select the option from the search results.
There, under ‘Select a Task‘ section, you’ll see 3 Headings-
- 3D Settings
- Display
- Video.
Choose ‘Video’ and go to ‘Adjust Video Color Setting’.
Here, enable “With the NVIDIA Settings” option and switch to the Advanced tab.
Now, select Full (0-255) instead of Limited (16-235) in the Dynamic Range menu.
Click on Apply to make the change.
Once done, you will notice the change in the display.
2] Change the Video card Settings
The issue mainly occurs with a problem on video on VLC with Hardware YUV>RGB conversion selected on Nvidia cards. By default VLC plays all the video of YUV MKV content with RGB 16 to 235 instead of 0,255. That is the VLC plays video in TV format from RGB 16 to 235. Disable the function that converts each frame from YUV which is a television format to RGB. This is a client-side fix for a YUV content.
Open VLC media player.
Go to Tool and click on Preference from the drop-down menu.
Click on Video.
In the Video Settings untick the option for Use hardware YUV> RGB conversions.
Enable Accelerated video output (Overlay).
Enable Window decorations.
Save to apply the changes.
Restart the VLC player.
3] Set OpenGL as the Output video method
Go to Tool and click on Preference from the drop-down menu.
Click on Video.
Locate the Output video method and select OpenGL video output from the drop-down.
Save to apply the changes.
Restart the VLC player.
If this does not help then select ‘Tools’ from the menu, navigate to ‘Settings’ and choose ‘Video’. Then you can try the following, in the order of decreasing playback performance:
- Switch to DirectX (DirectDraw)
- If that does not work, switch to Windows GDI video output and see.
I hope something helps.
