Blurred DVD playback with MPC-HC
Ultimately my aim is to be able to watch DVDs off my PC, upscaled to 1080p (either 25 or 23.976 progressive fps) through a DVI to HDMI cable to my plasma display.
So I was trying to set up and calibrate the display last night using the PAL version of Digital Video Essentials. Here is a screenshot of a resoltuion test: And here is what it looks like in MPC-HC v1.2.908.0: Looks like there is some kind of deinterlacing destroying the picture, but I've tried altering the settings in the MPEG-2 decoder, and in the video card drivers (ATI Catalyst Control Center) but cannot retrieve the lost detail. |

I hope to convince the mpc-hc developers to change the behaviour of this option in an upcoming release to make mpc-hc better out of the box. |

Have you tried changing the scaling options in the "Output" tab of mpc-hc. When using evr-custom presentation, you can select various resizing algorithms to use. The bottom most is the sharpest I believe. That might make the image sharper when scaled... worth a shot if you havn't tried it.

DVE displays still frame images not moving video for these tests. the screen is not redrawn until you manually refresh it. I have just done exactly this test here. I can confirm that using "auto" deinterlacing you get "bob" and half resolution - just what you see. "weave" correctly displays full resolution after you refresh the image. By the way, Cyberlink MPEG2 decoder displays full resolution in "auto" mode and uses DVXA. Generally I would recommend uisng an alternate MPEG2 decoder if you have one, if it can use DXVA and hardware de-interlacing. Last edited by Jong; 6th May 2009 at 15:09. |

Does the blurring also occur when playing in windowed mode? Resizing before deinterlacing is a possible cause of blurring.

Also tried using the Cyberlink video decoder within MPC-HC, and that gave the same results as well. However, if I play the disc with PowerDVD, then I get the full resolution. Last edited by FlimsyFeet; 7th May 2009 at 08:05. Reason: correct typo |

And it might help to list all the filters you see when you right click. Have you got ffdshow video decoder doing any post-processing? |

I don't know what I was thinking! The screenshot is clearly NOT bobbing (if it were the top right box would be all black and the bottom left all white). It is blending. Still changing to weave should fix it, as should using the Cyberlink decoder. That filter list will help.

Filters in use:
default directsound device video renderer audio switcher mpeg2 video decoder ac3 audio decoder dvd navigator I think it is something to do with the display scaling; if I take a screenshot now with alt+i it shows the full resolution. (Also, if I press F11 for full screen). It was probaby forcing "weave" that fixed it, but that didn't reflect in the winodwed display I was viewing. Edit: It appears to be caused by enabling View -> Video frame -> Keep aspect ratio Last edited by FlimsyFeet; 7th May 2009 at 22:14. Reason: more info |
