(Note that only the grayed out options are videos and audios in MKV that can't be imported on Windows 7) See the following test results on importing MKV into Premiere Pro CC 2018 on Windows 7. The fastest solution to import MKV files into Premiere Pro is changing the file extension from. mp4 or other Premiere Pro supported format. Sadly, this solution doesn't guarantee to work because changing the extension name won't affect what's inside the MKV container.

If the MKV contains Premiere Pro incompatible codecs like VC-1 and MPEG-4 Visual, Premiere Pro will still fail to read the MKV file. In addition, MKV can contain various video and audio codecs that might not be compatible with the new container format. Go to the video file on your file explorer. Input the new extension name that ends with. mp4 or other Premiere Pro friendly container format. Suppose Premiere Pro supports the video and audio codecs inside the MKV container, then simply remuxing MKV to MP4 will get the job done.
