6 Ways to Fix VLC 4K Choppy

• 1. Update VLC
• 2. Disable/Enable GPU Acceleration
• 3. Change Cache Time
• 4. Change VLC Video Output Settings
• 5. Amend FFmpeg Thread Settings and Loop Filter Skipping
• 6. Change 4K Video File Parameters

Can VLC play 4K (or some people call it 2160p)? Yes, but it can be extremely annoying to watch a super choppy 4K video in VLC that hampers the UHD video-playing experience. VLC 4K videos not playing smoothly or VLC 4K stutters are the common errors. The footage recorded in 4K at 60fps can be extremely lagging at times if VLC is not configured properly. Thus in this post, we will explain some of the leading causes behind the choppy 4K video playback in VLC, and show you the corresponding 6 fixes to the problem.

Why 4K Videos are Choppy on VLC

There are more than just one or two factors that can lead to your choppy 4K playback in VLC. And it could be related to the VLC player itself, your hardware, or even the 4K video. To sum them up, here are the top four reasons behind a choppy or stuttering 4K video playback in VLC.

• The resolution is too high

If the resolution of the video is too high, then it is possible that while running the video playback in VLC, you will have a lagged video that might buffer or stutter at many points.

• The frame rate is too high

The stuttering can also happen if the frame rate is high as well. This is because the GPU takes a longer time to render the frame than it is expected and sometimes it might even skip the frame. Once that happens, the video is bound to give a choppy output. That's in fact the trade off when CPU is overloaded. VLC enables frame dropping to decode fewer frames, thus causing the choppy video performance.

• Encoding affects the video playback

If the video coding engine is not up to the mark and 60fps video is being run with equal quality and speed, then the lag will be a continuous part of the playback and there will be a workload on the GPU.

• Slow system

If the system is too slow to decode the images, then the 4K video can also be choppy or stuttering while playing in VLC.

6 Methods to Fix VLC 4K Choppy

To fix VLC 4K video choppy issue, we have 6 possible solutions. They are updating VLC, disabling/enabling GPU Acceleration, changing Cache Time, changing VLC video output settings, amending FFmpeg Thread Settings and Loop Filter Skipping, and changing 4K video file parameters. Check how to fix VLC 4K choppy video in detailed steps:

Method 1. Update VLC

Update your VLC media player to the latest version. In fact, VLC 3.0 and higher versions provide better 4K video support.

Method 2. Disable/Enable GPU Acceleration in VLC

This method seems contradictory, but the situation various since users have different systems and hardware environment. Toggle GPU acceleration on or off? Feedbacks from users are divergent. Enabling GPU acceleration works for some users and disabling it works for others.

For instance, StackExchange user harrymac provided his example in the thread How to configure VLC to play 4K content properly. When Hardware-accelerated decoding is not disabled, 4K video freezing issues exists; when disabled, VLC can manager better frame rate, though it requires high-end CPU.

You can try to switch it on or off and stay with whatever works for your 4K videos.

Step 1. From VLC menu, click tools > Preferences.

Step 2. Click Input/Codecs, in Hardware-accelerated decoding, select Disable.

Step 3. Save settings, close VLC and restart it again. See if the 4K video plays smoothly this time. If not, follow step1-2 to enable hardware decoding.

Method 3. Change VLC Cache Time

Increasing cache value can improve the smoothness in video playback. You can change the File caching value from 300 (3 seconds) to 1000 for instance. Keep adjusting the value until you find one that suits you. Here are steps to change VLC cache time.

Step 1. Go to Preferences > Input/Codecs.

Step 2. Tick Show settings: All.

Step 3. Navigate to Input/Codecs advanced section, and change caching time.

Step 4. Save the changes, restart VLC and see if it fixes the VLC 4K choppy playback.

Method 4. Change VLC Video Output Settings

Changing output settings from automatic to DirectX, Open GL, and DirectDraw are proved as workable for many users. You can go to tools > Preferences > Video, and switch output settings.

Method 5. Amend FFmpeg Thread Settings and Loop Filter Skipping in VLC

This fix is from VideoLAN official forums, where many users found changing FFmeg settings works to avoid choppy 4K playback. Here are the steps.

Step 1. VLC menu Tools > Preferences > Select All in Show settings to manage advanced settings.

Step 2. Search for FFmpeg in filter box, or navigate to Input/Codecs > Video codecs > FFmpeg.

Step 3. Change threads from the default 0 to 1, 2, 3, 4 or other numbers.

Step 4. Save, close VLC and restart it. Load your 4K HDR videos.

Tips: You can also tweak loop filter skipping settings for FFmpeg until you yield a smooth 4K video playback.

Method 6. Change 4K Video File Parameters

Don't fret out if none of above method works. If you want stick to VLC instead of switching to default Media Player, VideoProc Converter AI can help you out. With this tool, you will be able to fix 4K choppy, stuttering or lagging issues, and compress unlimited 4K files as well as time-lapse videos.
