About MKV HEVC Conversion

Before getting into the conversion, the first thing we should be clear about is that HEVC and MKV are two completely different things.

HEVC, also called H265, is a video codec for encoding video data; MKV, however, is a container format that stores the video/audio streams, the codecs, and other metadata (e.g. subtitles). So, in a sense, it’s incorrect to say convert HEVC to MKV or MKV to HEVC since such conversion is impossible. What most people mean by saying this is that they want to encode MKV video with the HEVC codec or convert HEVC MKV to H264 MKV/MP4. (Tips: To learn more about video container and video codec, please read this article What is Video Encoding?)

The reason? Well, HEVC is an advanced video encoder that offers much better data compression at the same level of video quality when compared with other encoders. For example, if a 2GB H264 MKV video is to be re-encoded with HEVC (H265), the output size could be reduced to 1GB while the quality still remains the same (H265 vs. H264). Hence lots of people try to use HEVC to encode their movies to compress files. Yet, on the other hand, the HEVC codec and MKV container do not work on as many playback devices as H264 and MP4 can. So a group of people also wish to convert HEVC MKV to H264 MP4/MKV to achieve smooth video playback on any device.

Now, the good news is, you can make either the MKV HEVC conversion with only an HEVC converter. The following parts will introduce such a converter and explain how to convert “MKV to HEVC” and vice versa in detail. Read on.
