We wanted to let you know that we will be removing support for the MKV file format in the next updates of Adobe Premiere Pro and Adobe Media Encoder.

Our previous MKV file format was limited to decoding for playback. We have never offered support for encoding MKV, and overall usage of this format has been very low.

Users who need access to MKV files can consider third-party utilities. For rendering out video content for online platforms we encourage our users to take advantage of existing output options, such as H.264 and HEVC formats, which are widely used and supported.
