Playing a video stream on VLC has to go through four steps: access, demux, A/V decode, and output. And the output module is to present a video on our screens in the wake of the decoder turns a video into bitmap-like images. The reason why you need to change output modules is that various output modules provide different viewing experience. For example, OpenGL provides richer colors but takes more CPU utilization (depending on your PC specifications). So, changing output module maybe have a better result of playing of 4K video file in VLC.

6. Change Skip H.264 in-loop Deblocking Filter Setting.
When playing a video, you may notice small blocks appearing in flat areas, which is known as blocking artifact.
In order to reduce the artifacts in a video and improve video quality, a filter is applied to make the motion estimation more accurate, and this filter is called a deblocking filter. Skipping this in-loop filter can do harm to video quality but have a decent increase in playing high definition video streams.
- Step 1. Open VLC media player and click on Tool and choose Preference.

FFmpeg supports multi-threaded decoding for some codecs. If your processor has multiple cores, using multi-threaded decoding will take less time than single-threaded decoding. The number of threads used for decoding in VLC is set to 0 by default, which means it uses threads depending on the situation. Therefore, you can add to at least two threads for decoding 4K video files.

- Step 5. Remember to save the change and restart VLC.

File caching is used to solve the speed mismatch between CPU and memory, avoiding frequent access to data from memory and auxiliary memory, which improves the system efficiency and yields a better result of 4K video playback.
- Step 1. Open VLC media player and click on Tool > Preference.
- Step 2. Go to Show settings option in the lower-left corner and click on All.
- Step 3. Go under Input/codecs and click on the arrow in front of Video Codecs.
- Step 4. Find Advanced box on the right side and change file caching (ms) from 300 to 10000.
