Fixed - VLC Player Stutter and Lag When Playing HD MKV Files

VLC Player is a widely used player and encoder that supports many video and audio formats. Like other software, VLC users may experience various technical problems. One of the common technical problems you might often experience is VLC MKV playback issue: VLC stuttering or jumping when playing 1080p mkv; the audio(of MKV files) won't work at all; when open VLC, it just loads .mkv forever... Get frustrated? Don't worry. Here are 3 possible solutions to view 1080p/720p MKV with VLC flawlessly without any trouble.


Solution 1: Change Parameters

If the MKV file that is skipping is playing from a local hard drive, choose the "All" settings at the bottom of the dialog to show all of the options, then navigate to Input / Codecs -> Access modules -> File.

The caching value here is set in milliseconds, so setting the value to 1000 will buffer for 1 second (the default is 600, or 0.6 seconds). The problem with setting this option too large is that if you want to manually skip to a new point in the file, there will be a larger lag while the content is buffered again.

Solution 2: Disable hardware decoding

Some users resolve choppy VLC Playback on mkv files by disabling hardware decoding. Normally you would want hardware acceleration of the decoding process, but in some cases, it can conflict with your drivers, and it is worth a try.

Solution 3: Convert MKV Files

If you still can't play MKV files in VLC nicely after trying the solutions above, try converting MKV to another file format and then opening the clip in VLC Media Player.
