For users who take VLC as the main media player app, you may try to playback some 4K video shot with your 4K camera, camcorder, smartphone or downloaded from YouTube on VLC, however, one of most common issues when people encounter is the VLC 4K video playback choppy issues.
“I’m trying to playback 4K video from my GoPro in VLC and it’s super choppy, more actually freezes and that’s it. It’s not a CPU issue as the CPU isn’t pegged at 100. I tried it in the Movied and TV player in Windows 10 and it works perfectly. Any idea? I have GPU decoding enabled and I’m running a 980TI so I don’t think it’s related to that.”
“New to VLC & love its many options, however I am unable to play 4k video, doesn’t start then very choppy. No problem with other players so nothing wrong with my system or CPU. Would welcome any advice.Thanks.”
Although VLC can handle a lot of media playback perfectly, however, a lot of people even encounters video playback choppy issues when they try to play high definition movie such as 720p or 1080p movie, not to mention the large 4K video files. The good news is that there are solutions for you to fix VLC choppy playback issue with 4K or HD video.
Solution 1: Enable GPU hardware acceleration in VLC
If you are noticing choppy playback in VLC Media Player when playing high resolution video files, you may under certain circumstances benefit from gpu accelerated decoding in the media player to smooth things out. The feature in theory uses the processing power of the graphic card to lighten the load on the processor of the system.
Here are the detailed steps to enable hardware acceleration in VLC
Open VLC Media Player and click on Tools > Preferences or press Ctrl-P to open the settings window of the program. If you are using the simple settings interface, click on Input & Codecs on the left sidebar and check the Use GPU accelerated decoding box there.
If you are using the “all” interface select Input/Codecs > Video Codecs > FFmpeg > Hardware decoding instead to enable acceleration this way.
There are a couple misconceptions about this though that need to be addressed first before you can make an educated decision about it.
First, according to VLC’s GPU Decoding page, it is only available for H.264 streams. Second, the data is decoded in the GPU at the decoding stage and then transferred back to the player so that the other stages, filtering and streaming for instance, can be processed. This means that it can under circumstances be slower than without gpu acceleration enabled.
Last but not least, GPU decoding is only available for select operating systems. While Windows Vista and newer versions of the Microsoft operating system are supported, Windows XP is not at this point in time. The majority of graphic cards should support hardware acceleration just fine. Make sure you have installed the latest drivers though.
Solution 2: Play 4K Video with VLC best alternative 4K Video Player
Besides VLC, you can also play 4K video with the following powerful but free 4K video player.
5KPlayer is a new and a pretty powerful video player in terms of playing the HD videos. Apart from playing 4K videos, 1080p HD videos smoothly, it also lets you play 5K videos, which is the biggest advantage of this player over other players.
Media Player Classic and K-Lite Codec Pack
Media Player Classic, also known as MPC, is an open source free media player, mimicking the look and feel of Windows Media Player 6.4. As a matter of fact, MPC on its own cannot play 4K UHD videos. It needs the help from K-Lite Codec Pack. To make things easier, you are suggested to download K-Lite Codec Pack full package which covers Media Player Classic. Despite that it can work on even the oldest computers, you still need a more powerful system to perform 4K playback.
The KMPlayer at first only serves for Windows users. But in April, 2016, a Mac alpha version was released for Mac users with OS X 10.6 or later operating system. It supports for a wide range of file formats and can play videos in superb quality, including 4K UHD. According to the description in its official site, the PC edition only works on Windows 2000/XP/Vista/7(32bit). If you need a 4K video player for Windows 10, 8.1 or 7, you’d better choose another program, such as 5KPlayer.
This very popular and well known video player now supports playback of files up to 4K in resolution. It supports DivX HEVC video with the HEVC plugin, as well as regular DivX and DivX Plus. DivX Player is promoted as a very high quality media player and is one of the most popular choices.
