Part 1. Does Premiere Pro Support MKV Format?
Some versions of Premiere Pro support MKV files, while some versions don’t.
Only Premiere Pro CC 2018 (12.1-12.1.2) and Premiere Pro CC 2019 (13.1.2) support the import of MKV videos natively. So, if you are using other versions of Premiere Pro, you can’t import MKV files to Premiere Pro for editing. Also, the MKV container format can contain diverse codecs that all versions of Premiere Pro can’t handle.
According to Adobe Help center, we find that MKV isn’t on the list of Premiere Pro-supported file formats. In fact, MKV was a native support format in Adobe Premiere Pro CC 2018 12.1 and earlier, although any official announcement about this improvement can't be found. Below are words quoted from Adobe's blog:
"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."
And with the release of Adobe Premiere Pro CC 2019 13.1.3, Adobe removed the support for decoding MKV. Why Premier Pro dropped the limited support for MKV? Obviously, MKV is not the best file format for video editing in Premiere Pro. So, to import MKV files into Premiere Pro for editing, you need some help.
Part 2. How to Solve MKV File not Supported in Premiere Pro?
If your MKV file can play fine but can’t be imported to Premiere Pro, then the MKV file import failure can be due to incompatible file format or codec missing. In such a case, the MKV not supported in Premiere Pro error can be solved by converting MKV to a format or codec that is supported by Premiere Pro.
As mentioned above, some versions of Premiere Pro support the MKV file format. You may consider using such a version. In fact, the Premiere Pro CC 2018 (12.1-12.1.2) and Premiere Pro CC 2019 (13.1.2) also can’t support MKV files encoded with some codecs. Besides, these versions won’t give you the best video editing experience.

ffmpeg -i "original file name.mkv" -codec copy newname.mp4

Step 3. Now import the MP4 file to Premiere Pro CC for further editing.
