MKV Not Supported in Premiere Pro CC? Let's Fix It Now

Many people use the MKV format extensively. MKV files may be high quality Blu-Ray rips, OBS captured footages, or something else. However, when we try to import MKV file into Adobe Premiere Pro - the most popular industry standard video editing software in the world, the file import failure window will pop up with an error message "File format not supported" or "Unsupported format or damaged file".

I've been editing videos using a .mkv file format in CC 2019 on windows 10 but I noticed not only does CC 2019 on Mac OS not import .MKV but when I upgraded to CC 2020, my older projects and a new project I created doesn't let me import .mkv. I have no idea how I got mkv to work on CC 2019. – Adobe Support Community

Does Premiere Pro support MKV? How to import MKV files into Premiere Pro? We’ll answer these questions below.

Part 1 Does Premiere Pro Support MKV Format?

According to Adobe help center, we find that MKV isn't in 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 later, 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 CC 2019 13.1.3, Adobe removed the support for decoding MKV.

I recently updated Premier Pro CC to the version 13.1.3 (Build 44) and... all of the sudden, it no longer supports .MKV files. I've worked with this type of file for quite a while now, but right after the update, it won't let me use it. – Adobe Support Community

Why Premier Pro dropped the limited support for MKV? The Adobe Community professional RjL190365 and R Neil Haugen make a guess.

They can't code for unlimited number of codecs, and maintain performance and stability. So they are continuing support for some codecs that have still a large use in their pro base, and discontinuing lesser-used codecs. MKV is definitely a 'niche' use codec, no matter how good it may be.

Although MKV isn't supported in Premiere Pro, it doesn't mean that you cannot import MKV files into Premiere.

Part 2 How Can You Import MKV File into Premiere Pro CC/CS?

If your MKV file can play fine but can't be imported to Premiere, then file import failure should be due to incompatible file format or codec missing instead of file corruption.

Some people may suggest you to try installing the K-Lite Codec Pack to fix MKV import failure. However, we don't recommend this because this has been known to cause issues with the Adobe Suite, such as crashes, slowdowns and other issues.

Here we'll introduce 3 simple and workable ways for you.

Method 1. Rename File Extension

Sometimes, we simply need to change the file extension from mkv to one that Premiere supports and then we can get rid of file import failure.

Right click on your .mkv file, and choose Rename. Then, change the file extension from mkv to mp4, avi, or something that Premiere Pro can recognize. Then click Yes when a warning pops up. Once done, put the file into Premiere Pro and see if it can be imported without error now.

Method 2. Remux MKV File to MP4 Container

Sometimes, Premiere Pro can support the video and audio codecs in your MKV video but just doesn't support the MKV container format. In this case, you can simply remux the MKV file to an MP4 container without changing the video stream inside. WinX HD Video Converter Deluxe can remux files quickly and help you import MKV into Premiere without converting.

Step 1. Download and install WinX HD Video Converter Deluxe on your PC or Mac computer.

Step 2. Choose MP4 from the Output Profile window.

Step 3. Check Auto Copy.

Step 4. Hit RUN. Then WinX will put your video and audio files into MP4 container without recoding and re-encoding. No quality will lose. It is 10X faster than transcoding.

Method 3. Convert MKV to Premiere Pro Supported Format

If rename and remux don't work, it probably means that Premiere Pro doesn't support the video and audio codecs in your MKV video. Then, you need to convert MKV to a more industry standard format that Premiere Pro supports. This can also be easily done with WinX HD Video Converter Deluxe.

  • Support any HD/4K MKV file, no matter what video and audio codes are used.
  • Convert MKV files to MP4, MOV, AVI, H.264, and more Premiere supported formats. Batch conversion is allowed.

  • You can use High Quality Engine and choose HQ to get perfect output quality.
  • Also support compressing, editing, downloading, and recording video (record feature is only available in Mac version).

Click the download button above, install it, and follow our guide to convert MKV to Premiere Pro compatible format.

Step 1. Open WinX HD Video Converter Deluxe, and click the + Video button to browse and open target MKV file. Alternatively, you can simply drag and drop the source MKV file into this converter.

Step 2. Choose an output profile that Premiere Pro supports. Every profile has codec information. If you're not sure which one to choose, you can go to General Profiles, choose MP4 Video, and hit OK.
