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 files to DaVinci Resolve (now at version 18) - one of the best professional tools that take video editing to the next level, the file import failure windows will pop up with an error message "File format not supported", "MKV file not adding audio" or "DaVinci Resolve only shows the audio in the MKV file".

"Im trying to edit using an MKV file. The footage imports just fine. An audio track shows in the timeline but there it no actual sound or waveform, as if its just a silent track. The playback volume is up, and the audio plays fine if I view the file in vlc. Am I missing something? Its a 5g file if that makes a difference..."

Does DaVinci Resolve support MKV files? Why MKV file imported but there is no audio? If you're facing problems editing MKV files in DaVinci Resolve, you've come to the right place. In this post, we will show you how DaVinci Resolve works with MKV format and 3 workable ways to fix "DaVinci Resolve not support MKV file".

Part 1. Does DaVinci Resolve Support MKV Format?

DaVinci Resolve 17.2, which was released on May 12, 2021, can decode mkv clips. That means DaVinci Resolve 17.2 and above versions support MKV natively. Older versions like DaVinci Resolve 17.1, 17, 16, 15, etc. do not support MKV.

Does this mean we just need to upgrade older version to the latest version, then we can solve MKV editing or importing issues in DaVinci Resolve?

"I just updated to Resolve Studio 17.2 on my iMac (Big Sur OS). I read that Resolve can now import MKV files, but when I do this, all that shows is the audio. I've tried quite a few MKV files with the same result (and the file inspector only shows Audio). Is anybody else having this issue?"

As you see above, things might still doesn't work. This is because MKV is just a container format. Though DaVinci Resolve can recognize the MKV container, the things inside the MKV container might be encoded by codecs that are unsupported by the program, which will lead to file import failure or MKV no audio or no video after importing to DaVinci Resolve.

In fact, I was surprised when Resolve started to introduce MKV support in version 17.2, 18, etc, but there it is. It's buggy and incomplete and I wouldn't recommend ever relying on it. One of the greatest things about MKV as a format is the sheer amount of stuff it can contain - you can have multiple subtitles in there, multiple audio tracks and even multiple video tracks. But that's just a bloody nightmare to try to handle in editing software.

Part 2. How to Get DaVinci Resolve Work with MKV Files Beautifully?

Let's face it. MKV is not an editing-friendly format for DaVinci Resolve. As for DaVinci Resolve 17.2 or above are compatible with the MKV format, they might not support the codecs inside the container. To import MKV files into DaVinci Resolve without error and for further editing smoothly, we need to convert MKV to Resolve-friendly formats. Luckily, there are multiple ways to do that.

Method 1. Rename or Remux MKV to MP4?

Sometimes, we simply need to change the file extension from mkv to one that DaVinci Resolve 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 DaVinci Resolve can recognize. Then click Yes when a warning pops up. Once done, put the file into DaVinci Resolve and see if it can be imported without error now.

Or, you can use a video remuxing software to remux MKV to MP4 so see if it works.

Method 2. Convert MKV to MP4, DNxHD, ProRes for DaVinci Resolve

If rename and remux don't work, it probably means that DaVinci Resolve doesn't support the video and audio codecs in your MKV video. Then, you may have to convert MKV to a more industry standard format that DaVinci Resolve supports. EaseFab Video Converter for Mac ( or EaseFab Video Converter for Windows) can quickly help you convert MKV to DaVinci Resolve highly compatible MP4 (codec: h.264+aac), MOV, DNxHD, Apple ProRes without any quality loss.

● Support any HD/4K MKV file, no matter what video and audio codes are used.
● Convert MKV files to MP4, MOV, H.264, DNxHD ProRes and more Resolve supported formats. Batch conversion is allowed.
● 30X real-time faster conversion speed thanks to the support for Intel/NVIDIA/AMD hardware acceleration.
● Also support compressing, cutting, cropping, merging, adding effects, etc.

Guide: How to decode MKV to DaVinci Resolve supported formats

The step-by-step guide is almost the same on Windows and Mac. Here we will take EaseFab Video Converter for Mac as the example.

Step 1. Download and launch EaseFab Video Converter on Mac or Windows PC. Click Add Video to import your MKV video. Dragging and droppping works too. (Note: batch conversion is supported, so you can several mov videos to the program to convert at a time.)

Import MKV Video File(s)

Step 2. Click the Profile drop-down list and move mouse cursor to Editing Software category. Here you're recommended to select ProRes for transcoding MKV to DaVinci Resolve on Mac. For Windows users, you're recommended to use DNxHD as the output format.

Besides the high-quality codecs, you can also select MP4 (codec: H.264) or MOV (H.264) from Common Video category for further using in DaVinci Resolve.

Important Note: Though high-quality ProRes and DNxHD codecs typically need ten times as much storage than the H.264 codec video needs, they are specially designed for heavy editing task and they trade storage space and bitrate for quality and ease of processing.

Choose DNxHD or Apple ProRes for DaVinci Resolve

Step 3. (optional) You can cut, crop, merge, rotate, etc. to make some easy video edits in a linear manner with EaseFab Video Converter. You can also click Settings button to adjust the codec, resolution, frame rate, bitrate, etc.

Step 4. Hit Convert and it will begin fast video decoding, conversion and processing your MKV video at one go.

After the conversion is complete, get the resulted files via clicking the Open button. Now you can import and edit the converted MKV files in DaVinci Resolve without any trouble.

Method 3. Convert MKV to MP4 via VLC

VLC media player, widely known as a cross-platform and multiple media player, can also help you convert MKV to MP4 for importing to DaVinci Resolve. However, considering its confusing UI design, slow conversion speed, and limited codec options, I only recommend VLC media player for users who've already installed VLC to convert MKV for DaVinci Resolve.

Step 1. Go to the official site of VLC media player to download and install the software.

Step 2. Launch up the software, click on Media on the top menu bar, and choose Convert / Save.

Choose Convert / Save option in VLC

Step 3. Hit Add, choose the target MKV file that you want to import to DaVinci Resolve and hit Open.

Step 4. Hit Convert / Save on the right bottom of the Open Media panel.

Step 5. Click on the down-triangle button, choose Video – H.264 +MP3 (MP4).

Convert MKV to MP4 via VLC

Step 6. Select Browse, choose the output file folder. Hit Start. That's it.

Besides VLC, you can also use Handbrake or FFmpeg to convert MKV to MP4 for DaVinci Resolve.

Part 3. MKV or MP4 Editing Performance Issues in DaVinci Resolve

After making sure DaVinci Resolve can import your mkv file (or transcoded mp4 file), you start editing your footage. You realize that Resolve is struggling to playback the footage smoothly in real-time. This is mainly due to the codecs H.264 or H.265 of your mkv or transcoded mp4 file.

Both of them are highly compressed codecs – especially H.265 is more compressed than H.264. So naturally, your CPU/GPU is under tremendous load to unpack them (decode) and process them in real-time.

The best option is to convert your MKV files to ProRes or DNxHD codec for DaVinci Resolve with EaseFab Video Converter or any other video encoding software. What's good is that they don't compress the video as much. They trade storage space and bitrate for quality and ease of processing. They typically need ten times as much storage. That's a lot, but hard drives are tending towards being free, so it hardly matters these days.

Both ProRes and DNxHD are effectively "visually lossless" at their higher bitrates. That means exactly what it says: you can't tell the difference between your original video and the same material encoded to ProRes or DNxHD.

Once you've converted, your edits will fly. These codecs are so efficient that you can play multiple streams with a fraction of the effort you need for a single stream of H.264 - based video. As an example, on my Macbook Air, playing any HD Long-Gop clip will cause the fan to come on at full power within seconds, but with ProRes, I can play a clip - in much higher quality - with no sign of the fan.
