Topic: Blurred Blobs when there's Motion

http://i.imgur.com/K30hxKa.jpg   I'm not sure why this is happening.  I installed an AMD driver so I assume that's the issue but how do I fix it???

It is interpolation artifacts.
You can't remove them completely. But you can reduce them.

What settings are you using?
SVP tray menu - Information - Additional information

That opens up a blank txt document named debuginfo.txt.  Also thank you for your quick reply, much appreciated.

Open your video with artifacts from picture in the first post. Wait while SVP make his work. Triangle in tray menu will become green.
Then open Additional info.

Re: Blurred Blobs when there's Motion

Your video has framerate 23.976 fps, your display has refreshrate 59.997 Hz.
So you get not integer multiplier.

Smooth factor: 5:2

Try to switch you monitor to 48 Hz mode or to 72 Hz mode.

Re: Blurred Blobs when there's Motion

How do you make a 60 Hz monitor run at 48 Hz? And if it doesn't run at 24/48/72 etc. frequencies then it would have artifacts?

Re: Blurred Blobs when there's Motion

If you're using amd, you could change the refresh rate

http://i.imgur.com/O7O38NO.png

it's about exact multiple from video frame rate. If the video has 24fps, then the exact multiple will be 48, 72, ...
If the video has 30fps, then 60hz will be the exact multiple.

Re: Blurred Blobs when there's Motion

I have GTX580 mate, its Nvidia. I created a custom resolution under Nvidia Control Panel and used 48 Hz but the monitor went black and said current input settings not supported by the monitor, so I am guessing this monitor (U2412M) only supports 60 Hz. I thought going lower frequencies should not have any problem, but I was wrong.

Re: Blurred Blobs when there's Motion

Yeah, that's must be it.

I'm too, when changing the refresh rate to lower, from 60Hz -> 48Hz, it automatically lower the resolution too.

The best you can do to reduce the artifact is by changing target frame rate to 2x or 3x instead of to target display refresh rate. Exact multiple is always the safest option, smoothness wise and artifact-less wise

If the video has 24fps, you have to play it to 48fps interpolated, this would be less smooth but it certainly less artifact than to 60fps
but if the video has 30fps, then you're lucky because the interpolated frame rate is same as monitor refresh rate, viz. 60

Try to make custom resolution with 72 Hz refreshrate. It works in more cases. 48 Hz works very rarely.

It is not so. When you watch 48 fps at 60 Hz display you see some frames twice. To reduce visibility of artifacts It must be only source frames not interpolated. So I recommend use 2m Frames interpolation mode with Target frame rate To screen refreshrate. It is the same 2x but doubleframes are garantee source frames.

Re: Blurred Blobs when there's Motion

Protip: you can change your refresh rate on any GPU, including Intel and Nvidia, without the need for making a custom resolution:
http://windows.microsoft.com/en-us/wind … =windows-7

The only reason you'd need to make a custom resolution is if the refresh rate in question isn't available.

Also note, AMD Radeon users need to use CRU - Custom Resolution Utility in order to make a custom resolution.

Re: Blurred Blobs when there's Motion

2m interpolation does make artifacts almost non existent, true, but the purpose of SVP gets kind of killed. I mean there's a HUGE difference between 2m interpolation and the default adaptive mode, once someone sees the default mode it's rather hard to go to anything else smile.

Right now I am more or less happy with 1m interpolation and artifact masking at above normal. Artifacts are there, but in much lesser extent.

PS: This damn monitor doesn't support 72 Hz either, tried that already. I am buying a 120 Hz monitor soon big_smile
