View Full Version : Video playback issue and question.

I'm using MPC-HC on EMR Custom, Bicubic 1.0 Resize with CoreAVC as a decoder.

The issue I'm having is with scenes that are dark but have lighting in them. An example of my issue I would describe as a candle on a black background. As the light is further from the candle a type of banding occurs. Instead of a smooth transition from light to dark, it appears as different levels of brightness. Is there a correction for this? Is it just part of the quality of movie I am watching?

Also, is there a guide or suggestions for MPC-HC shaders I should be using? I mostly watch 720p, 1080p movies, but also anime. I use CoreAVC for h264 playback of course and FFDShow for everything else. I did find a guide advising different Blurs and Sharpenings and such within FFDShow, but of course those corrections won't affect h264 playback since I use CoreAVC.

Thanks.

Edit: I actually turned on the 16-235 -> 0-255 shader and it removed the banding but at the same time made the video a little darker. I'm still accepting suggestions if anyone has any.

Edit2: I then changed the output levels to Auto Detect in CoreAVC which I can only assume changed it to 16-235 instead of 0-255 like I had set. I was able to remove the MPC shader at this point.

You can get ffdshow to load if you enable its raw video processing on the codecs page. Then you can Use ffdhow as a post-processor for most videos.

Anyway, to remove banding using ffdshow, enable the Deband filter.

I did a right side only processing and it definitely looks better. have any suggestions for any other settings?

If you want to hide them more try: raise the deband threshold, use the noise filter, use something via the avisynth filter. As for other problems that one might want to correct, I sometimes use the levels filter with gamma at 1.2, turn on deblocking, use the internal resizer and very occasionally use the sharpen filter.

I get lagged video when using FFDShow with CoreAVC, but my CPU doesn't have pegged % usage. What else could cause this? GPU or something?

Sorry, I have no idea. If you are not running out of cpu power then it should work fine together. I haven't got CoreAVC but it works with other decoders (WMV and MPEG2)

Quick question:

Are you watching this on a computer monitor or a TV? LCD?
