Windows 8 videos are grainy and have jagged/rough edges (PIC) Incl

[marybus]

Hi All

This seems to have been a very common issue for many with Windows 7 and now this is a issue in Windows 8

All my videos played fine in WinXP now on this brand new computer with windows 8 I am getting grainy / jagged edges problem.

What I have already tried

I am running win8 64bit computer model is samsung dp700a3d-k02us
Updated the video drivers
Downloaded codecs including klite, xvid, bsplayer, vlc, MPC etc (made sure to remove and then test new etc)
Downloaded quicktime to test same issue
Played with the options / filter

Only reason im not jumping the gun and blaming it on hardware failure is because too many people have this same exact issue right after upgrading a machine that had XP to win7 or 8, in other words in their case it cannot be a hardware issue and the web is loaded with these posts most are from a few years ago, my guess is many are reading the posts there and either resolving it or like many say they go back to xp.

I am hoping someone here can shed some light on a fix, it will help myself and a ton of others.

The pic below is thanks to others who posted photos describing the issue, kindly ignore any text on image, just look as a sample to see the issues, left ok right side bad.




thanks in advance

looks like the deblocker during decoding is not working.
If you use MPC-HC:
- Which decoder is used during playback?
- Which renderers have you tried?
- Have you tried using madVR in combination with MPC-HC?

[TreeTops]

Hmm..On the top two, the one on the right looks better to me. On the bottom two the one on the right is same as left but enlarged so it would normally be a little fuzzier. Posting someone's photo may not help us figure out your problem. But you have a different video correct? What is the video source?

Since I no longer have my win xp i cant take proper screen shots of the same content to post, but all the photos I found online of the problem are exactly the same.

Another hint here for the experts, videos that have text in the start like say a title called "Video One" the video starts playing, it takes a a second for the text to become sharp first its fuzzy.

Really a big mystery here

[jagabo]

Post a screen cap of the bad video. Made on your computer, not somebody else's that looks similar.

Perhaps more information would help. What file TYPE is that? MP4, AVI, WMV? What kind of format and encoding methods were used.

My suspicion is that its an AVI with XVid or DivX, at any rate a X263 encode and the player has the deblocking off as it should with MP4 but not with Xvid. MP4 has inline deblocking during the encode and does not need deblocking from the player. Xvid NEEDS deblocking from the player unless a very high bit rate was used. The spray looks very much like Xvid blocking at too low a bit rate.

In any case you need to give us a bit more info as the what files are. A printout from Mediainfo would help a lot.

[Atak_Snajpera]

Most likely your re-sizer was not set at least in Bilinear mode
MPC-HC

[marybus]

Thanks for trying to help
To Atak tried that with no luck

I am posting some samples, keep in mind when I paused video to take screenshot it made it a bit worse on the pause but its pretty close to how things look.

I tried all file types mentioned in my orig post all with same result,

[Atak_Snajpera]

Now I suspect that you have activated some dumb deinterlacer. Can you post screenshots on some high quality 720p rips or 1080p?

[jagabo]

The first is probably just too low a bitrate. The second is an interlaced source encoded progressive. The last may have been poorly interlaced. What does a well produced video look like?

[marybus]

all these videos where great on win xp pro and win vista

well produced videos might have less jagged edges etc but still not clean

bottom line, on win xp these videos looks 50x better

[Atak_Snajpera]

upload sample for us and we will judge

[jagabo]

How does this 1080p clip (Blu-ray rip) look on your computer? Here's what I see:

[jagabo]

And how about this clip (full screen)? The idea is to isolate decoding (paramount.mkv) and scaling (xvid2.avi).

[marybus]

hi

here is a sample I downloaded from demo world called souther paradise
Dolby Digital 2.0 1080/29.97p 20.02.10
amazing how crystal clear it is, the screenshot might degrade it a bit but its amazing

[Atak_Snajpera]

problem solved! next!

[marybus]

xvid file


mkv file


on xvid file notice the roof on the building on the back has a big jagged edges while mkv is clean

thanks again

[marybus]

problem solved! next!

can you elaborate please? meaning what do I do to get the windows 8 machine to show clear videos (same videos on this machine where great on xp and vista)

or does windows 8 only play high def files etc good and older files it degrades lol?

[Atak_Snajpera]

do not expect super detailed image if movie is not in your lcd native resolution. upscaling will always degrade image quality.

Xvid is in 720x480 while mkv is in 1920x1080 !

So once again. Problem solved! Actually problem never existed You just have crappy sources. That's all.

[jagabo]

xvid file

mkv file

[Attachment 19116 - Click to enlarge]

on xvid file notice the roof on the building on the back has a big jagged edges while mkv is clean

Your images look about like I would expect. Except the the Xvid image is over sharpened. Go to the graphics card's setup applet and turn off all the video "enhancement" features. The applet is different for different graphics cards but here's an example of one:



Also, did you do what Atak_Snajpera suggest in post #8?

first off thanks allot, I happen to have the same interface as you (intel) I copied your settings and a huge part of the fuzzyness and jagged edges are gone! Thing is I went from a 19 inch old monitor (square) to a 23inch lcd so like atak said it wasnt high quality all along its just more pronounced with my new system.

As far as post number 8 I copied all settings, but there is one checkbox that is checked and greyed out and I cannot uncheck it, that is the box vmr-9 mixer mode,

thanks

[jagabo]

Another thing you might try is disabling the DXVA decoders in MPCHC. View -> Options -> Internal Filters (left pane) -> Transform Filter (right pane): H264/AVC (DXVA), VC1 (DXVA), WMV (DXVA). Only use the software decoders (the FFmpeg equivalents).
