实现PC视频播放最强画质教程( PotPlayer播放器+MADVR插件)
(3) Image upscaling: Image upscaling means image enlargement. As long as the output target resolution is greater than the original resolution, this part of the algorithm will be used. For example, 1080P resolution video is played on a 4K moniTor.
Here we can choose to use ?doubling (image doubling) or ?upscaling (image upscaling). The former effect is much better than the latter, so if you can open it, let's open it. (Of course if the graphics card is not very good, do not use ?doubling?)
If you are confident about the graphics card, you can open NGU Anti-Alias, and set the drop-down box as shown in the figure below.
Here pay attention to the option of the fourth drop-down box (activate doubling): what we choose here is "...always -supersampling", which means to always enable ?NGU? for doubling.
The original default "let madVR decide" means that the width or height of the target resolution is greater than or equal to the original resolution ?1.2? times to enable ?NGU, if it does not reach ?1.2? times the enabling conditions, it will use ?Jinc?+? AR? Alternative.
If the above settings are a bit difficult, you can adjust the option of the first drop-down box (luma doubling) to medium.
If the configuration is medium, it is recommended to set it to Jinc + AR under "upscaling".
If you can't bear the graphics card, you can consider: Lanczos 4+AR (HD4600? level set display) or even Cubic? Bicubic60+AR (HD4000? level set display).
(4) upscaling refinement: The purpose of the sharpening algorithm is to improve the blur caused by the magnification Operation, and it is only used after the video is large.
4. Frequently Asked Questions 1. Will the screen be blacked intermittently when playing a video?
Trouble phenomenon: When Potplayer? plays a video, it will automatically switch back and forth between ?windowed? and ?exclusive? (the word switch will appear in the upper left corner of the video) from time to time. In this way, the entire interface will be black every time you switch.
The cause of the problem: madvr? The default is to use the full-screen exclusive mode (exclusive). Although this mode has its advantages, the above problems will occur if the computer configuration is not enough. Just turn it off.
Solution: Open the setting page of madVR. In the "rendering"->"general settings" selection, uncheck the "enable automatic fullscreen exclusive mode".
2. How to judge whether the setting is suitable or not, we choose the highest setting possible under the premise that the playback is not stuck. Whether it is stuck or not can be judged like this: You can use ?fraps? to check the frame rate. In full-screen mode, it should be equal to the refresh rate of your monitor. In window mode, it is generally the output frame rate.
You can also use the GPU-Z to view the GPU load. If it is less than 90%, there is no problem. The original text is from: www.hangge.com?? Please keep the original link:
