“I have used PotPlayer for a long time. Recently, I tried to play some PotPlayer 4K videos on my computer and a weird thing happened. PotPlayer starts playing the clips with a black screen, then the clip plays back in stop-motion after hitting stop and play.”

While some friends search for how to solve the PotPlayer 4K playback issues, the question comes to us. Is the PotPlayer 4K codec really available within the program? To dig out the truth, I would like to share some good solutions to help fix the PotPlayer 4K video playing problem in this article.

Part 1: Can PotPlayer Support 4K Playback

Released several years ago, PotPlayer has been growing up with amazing updates lately. Being a popular multimedia player, PotPlayer seems to support a large range of media formats such as AVI, WMV, FLV, MP4, MPEG. Common sense tells us playing different video and audio content requires corresponding codecs. In other words, streaming PotPlayer 4K video movies is only workable through necessary 4K codecs. At the moment, you may wonder where the PotPlayer 4K codec is.

Generally speaking, the majority of 4K movies come in MKV and MP4 files. That means PotPlayer is supposed to offer PotPlayer 4K video playback for most media. However, a number of PotPlayer users find that they can’t play MKV movies on PotPlayer. Although methods to deal with such situations vary, it is hard to get a solid answer to this question if the PotPlayer 4K codec is installed. Lots of people may figure out the latest PotPlayer release is more likely to contain the PotPlayer 4K HDR codec solutions while old versions face unknown problems.

On another side, there could be other factors impeding the PotPlayer 4K video reproduction. For instance, the external LAV filters will probably have conflicts with PotPlayer 4K HDR codec performances. Also, the computing systems matter in a distinct way whereas the 64-bit edition is proved to be more compatible with numerous PotPlayer 4K video displays and fewer mistakes. Next, I will introduce a couple of strategies to address the annoying trouble.

Part 2: How to Solve PotPlayer Won't Play 4K Videos

Well, there are many procedures to achieve the same goal of how to settle the PotPlayer 4K output problem. Besides trying to configure the puzzling PotPlayer panels, you can have other options. To be more precise, it is possible to convert 4K videos to 1080P (HD) or other widely acceptable formats while retaining the highest quality using a handy transcoder. Alternatively, you can turn to another powerful 4K player.

Before the first step, make sure the PotPlayer version is the latest one. Just check the title menu and move to the last option of “About” to see if there is any new version available. If you are applying an out-dated PotPlayer on Windows, it is simple to go with the update instruction then download and install it properly. Notice that adopting the x64 version of the PotPlayer will have a better chance of success. Once you have completed the preparation, follow the detailed steps below to disable the LAV filters.

Step 1. Open the PotPlayer program

Needless to import any media files, you can double-click the PotPlayer icon to view the interface.

Step 2. Navigate to the “Preferences”

The confusion may appear while the home page looks difficult to conduct operations. Be aware of the title banner and a small drop-down button next to the logo. Click on the triangle to call out the main menu. You need to scroll down plenty of items and find the “Preferences” near the bottom.

Step 3. Choose the “Filter Control” tab and the “Filter management” button

The last click will activate an advanced panel full of massive options. In the left side menu, look for the “Filter Control” and expand the headline to view further selections. “Source/Splitter” submenu is sitting at the top. Select it to extend the right window. As can be observed, most cases include built-in MKV and MP4 sources. At the lowest part, click on the “Filter management“ to another dialog box.

Step 4. Scan the potential PotPlayer 4K codecs

Don’t be afraid if you haven’t seen any of those terms. Simply hit the “Scan” button to detect the LAV filters. Usually, they will be bundled as a group including LAV audio decoder, LAV video decoder, LAV splitter, LAV splitter source.

Step 5. Go to the “Filter priority (Overall)” tab

Here the “Custom Filter Manager” will list the external LAV filters. A single click on each check-box in front of the LAV group filters then select the “Delete” button to clear up all of them.

Step 6. Hit the “Apply” and “Ok” to confirm the changes

Restart the PotPlayer to repeat steps 1 to 5. When the control board shows blank content, it is time to input some PotPlayer 4K videos to test the outcome.
