View Full Version : Colour of DVD subtitles off in MPC

Hi,
If I watch a DVD movie with subtitles in PowerDVD the subtitles look fine, black edges with solid yellow fields inside. However when using MPC (and with the internal mpeg2-decoder on) the inner subtitle colour (chroma/luma?) is always a couple of pixels off on the x-axis, creating an annoying effect where there is some yellow missing inside the edges and an equal amount of pixels of orange is seen outside the edges of the subtitles instead. What could be the problem and is there any way to fix it? I'm pretty sure it worked if I used the CyberLink Video/SP Decoder in overrides, but I'd rather not do that.

That's happening probably because you are running the decoder in yv12 mode where the chroma planes only have 1/4 of the full resolution, and where there is no way to map the colors to the pixels individually, each painted color affects 2x2 pixels making it look like washed away a bit. If you disable yv12 in the options, the second fastest (yuy2) color mode will be used, this is a bit better/slowe since one color is distributed between 2 pixels only (horizontally).

I unchecked the 'Enable planar YUV media types' option and it looks a lot better now, thanks!
