Remove Vertical Lines in movie - Edward - 14.03.2018
Hi.
I want help to clearing up a movie with Vertical Lines!
The first image is my original movie, and the second is my encoded with DeGrain.
What are these vertical lines? And how to clear up them?
RE: Remove Vertical Lines in movie - Selur - 14.03.2018
DeGrain is the wrong filter for this, that is no grain or noise.
Looks more like a job for Avisynths DeFreq (https://avisynth.org.ru/defreq/defreq.html), Vapoursynths vcFreq (http://www.avisynth.nl/users/vcmohan/vcfreq/vcfreq.html) or Avisynths DeStripe (http://avisynth.nl/index.php/DeStripe) which are all not supported in Hybrid.
Also just saw something through my online search which looks like your problem: https://forum.doom9.org/showthread.php?t=163574
-> if you can share a few second long sample I can try looking into it some more.

Thank you very much for your guide.
Here, the sample for testing.

Got the file will look into it.

That file doesn't have any vertical lines such as you showed,.. -> seems like this is a playback problem on your end or the wrong sample.
In case you use a Radeon card, make sure you turn off the demo or any addition filtering in the video settings in your Radeon settings.

In normal play can't see those vertical lines, but with shaders in mpchc you can see vertical lines.

That aside I think I see something like those artifacts in the short scene (cut in) where the flower opens (frame 526-672).
So do you also only see those artifacts in that scene?

Yes, In that scene you can see without any shader. but if you use shader, can see those vertical lines in the all scene.
RE: Remove Vertical Lines in movie - Selur - 14.03.2018
Give me more details, because I can't see those artifacts when I just add a shader.
Just added Denoise to pre-resizing and the artifacts are still only in that scene.

Ps.: if you overclocked you gpu in any way or it is overclocked by default, this might be caused by overclocking,...

I use this shader to see that vertical lines:

Add that shader file in mpc-hc Shader presets and enable it.
Go to:
mpc-hc>View>Options...>Shaders
Click on "Add Shader file" and select shader file
Select Shader file in left box and click on "add to pre-resize"
Add a name for it on the "Shader presets" box and click on save.
Now play movie in mpc-hc and click ctrl+z
