About MKV HEVC Conversion

HEVC/H265 is an advanced video codec for encoding video data, while MKV is a popular container format. People like to use HEVC to encode MKV videos because compared to other encoders, HEVC offers much better data compression at the same level of video quality. For example, if a 2GB H264 MKV video is to be re-encoded through HEVC (H265), the output size could be reduced to 1GB while the quality still remains the same (H265 vs. H264). On the other hand, HEVC is not widely supported as H264. So a group of people also wish to convert HEVC to H264 MKV or MP4 to achieve smoother video playback.

The following post will go over how to convert MKV to HEVC as well as change HEVC to MKV H264 with a powerful video converter. Read on for more detail of the MKV HEVC conversion.
