Cannot to Import MKV into Vegas Pro? 3 Fixes Provided!

As stated previously, Vegas Pro has added an MKV reader option to Vegas Pro since the Vegas Pro 17 version.

You can upgrade your Vegas Pro to the latest version and then enable the MKV reader option in the preferences settings to get the MKV format support.

However, since the MKV format is still not included in the tech specs page of the Vegas official website, you should make sure the video and audio encoders in your MKV file are supported by Vegas Pro. Otherwise, you may still encounter the import error.

Follow the steps below to enable the MKV Reader option.

Step 1. Launch Vegas Pro and click "Options" from the menu.

Step 2. Select "Preferences" and switch to the "File I/O" tab.

Step 3. Check the "Enable MKV Reader (Experimental)" option.

Step 4. Close Vegas Pro and restart it. Import your MKV file to Vegas Pro to see if it works.

Step 3. Press the right-side format image to open the output format library. Go to the "Video" tab and select "MP4" or other Vega Pro supported formats.

💡 For better editing performance, you can also go to the "Device" > "Apple" tab to select ProRes as the output format.

Optional: You can open the "Parameter settings" to modify the video codec, resolution, bitrate, frame rate, etc.

Step 4. Click the bottom ▼ button to specify an output path and press "Run" to start the conversion.

💡 The conversion process depends on the file size and length.
💡 Hardware acceleration (Intel QSV and Nvidia NVENC) can be enabled for H.264 and H.265/HEVC encoding to improve the conversion performance, and speed will be greatly improved.

Sometimes, renaming the file extension can also help solve the MKV Vegas Pro import issue.

But note that if you want to change the file extension, ensure the video and audio codecs wrapped in your MKV files are compatible with Vegas Pro. Also, the new container format should support the video and audio codecs in your MKV files. Otherwise, the original file may be damaged.

For example, if your MKV video is encoded with H.264 and AAC, you can directly rename it to .mp4 since the MP4 format also supports H.264 and AAC encoders.

Anyway, before renaming the file, you'd better back up the file.

Follow the steps to change your file name extension:

Step 1. Find the video file in your file folder.

Step 2. Right-click on the MKV file you want to edit. Choose “Rename”.

Step 3. Input the new extension name that ends with .mp4 or other Vegas Pro-friendly container formats.

Step 4. Press the “Enter” key and hit “Yes” on the pop-up confirmation box.
