Something You Gotta Known Between MKV and Adobe Premiere Pro
MKV was natively supported in Adobe Premiere Pro 2018 12.1 and later, but there is no place to find any official announcement about this improvement. And till now, MKV has not been added to the official supported format list. Why Adobe remove and doesn't add the the ability of Premier Pro to import .mkv files? Maybe we can find the answer from some words from Adobe's official 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."
Actually, the reason varies. You should know that codec format decides whether you can load a video or audio file successfully or not, while MKV is just a container format. So even though you are importing an .mkv video, the encoded file wrapped in the MKV box might not be supported, which leads to file import failure. Also it could be caused by an old-version Premiere Pro. Different Operating Systems have an impact on it as well.
MKV Import Failure in Adobe Premiere Pro is mainly due to incompatible file format or codec missing, which can be easily solved by transcoding MKV to other Premiere freindly formats with video converter software like EaseFab Video Converter.
