As the title says, is there any way to adjust color levels in VLC? It always plays back videos in TV levels format (RGB 16 to 235) so if I ever wanna watch most of my movies that are still in this format, I have to use mpc otherwise it looks very washed out.

In short, I'd very much like to know if it's possible to somehow make VLC convert the color levels from (16,235) to (0,255)!

You can use the "Extended GUI" to change Brightness, contrast, etc.

Depending on the power of your PC's CPU and whether your video card offers "hardware accelaration". You could try visiting: Preferences -> Video, and "uncheck" the "Overlay Video Output" option.

If you use DirectX 3D output, go to DirectX output module, be sure advanced options is checked, then uncheck "Use hardware YUV->RGB conversions". That'll correct the luma range from 16,235 to 0,255.

If you have an nvidia card, there should also be a registry tweak that enables the conversion, that would be the best way I think, so you can make use of your hardware, but I don't know much about this tweak. I think I've read that it doesn't even work in the newer forceware drivers.

Thanks, this corrects it perfectly!
