MKV won’t play because of HEVC codec, how to fix?

MKV won’t play because of HEVC codec? Read this post to learn a workaround to make HEVC MKV movies play correctly.

Issues playing HEVC MKV movies through VLC
“Hi all, I am having issues playing HEVC MKV files on my system. I have a Windows 8.1 64 bit PC with 4GB RAM and Intel Core i5-4210U processor @2.40GHz. I tried the latest version of VLC player, and it can smoothly play 1080p H.264 MKV videos but sadly not the 1080p HEVC MKV files. I experienced very choppy playback, skipping frames, grey screens and audio and video out of sync issues. It’s totally unwatchable. Is there any way to fix this? Any solutions guys? Thanks for any advice.”

The reason you’re able to play H.264 .mkv files more smoothly is likely to do with the level of compression. In comparison to H.264/MPEG-4 AVC, HEVC (also known as H.265) offers about double the data compression ratio at the same level of video quality, or substantially improved video quality at the same bit rate. So because your HEVC files are more compressed, your computer has to do a lot more work per frame to uncompress everything.

An easy solution we suggest is converting HEVC MKV videos to the widely-accepted H.264 MP4 files. It’s maybe not the best possible solution, but it’s at least one solid workaround, and it’s worked for us when we had similar problems in the past. Here’s how.
