Follow our quick guide and learn how to downscale Ultra HD 4K MKV files to 1080p/ 720p with three simple steps on a Mac.

Step 1: Launch the Program and Import MKV Files

Getting 4K .mkv videos onto the program is a simple matter of opening the folder on your computer and dragging the MKV files contained in it to the program's window. Alternatively, head to the toolbar and use the tradiitional "Add File" option to load your files.

You can preview the videos on the right area to make sure they are exactly the ones to work on.

Step 2: Tweak the resolution in "Settings"

If you stick to MKV format, you can click "Profile" down-down menu in the lower left-hand side of the interface and set MKV Video Format (*.mkv) as output format from the list. Other formats are also available, depending on your specific needs.

Next, click "Settings" near the "Profile" option to open up Profile Settings window. In Resolution field, set the value to 1920*1080 (aka 1080p) or 1280*720 (aka 720p). It's worth pointing out that the lower your resolution is the smaller your file size will be and vice versa.

If you don't have much knowledge about other parameters such as Aspect Ratio, it is wise to ignore them because you don't want black bars to appear on the sides on a display, which leads to a great discount on movie watching experience.

Furthermore, it's possible to select a device-oriented preset from the presets list. Each preset contains already optimized settings for popular device you choose: Apple iPhone, iPad, TVs, Samsung, Huawei, Sony, HTC, Xiaomi, LG, and the like.

Step 3: Begin converting 4K MKV videos to 1080p/ 720p for Mac

Before you get started, please pick a directory on the local hard drive to save the video to. You should spot the "destination" option in the lower left corner of the interface.

Now let's start the process. Hit the big "Convert" button to embark on the MKV 4K to 1080p/ 720p conversion process. Since the length of every movie is different, the time to finish may vary, but basically it can be complete in a fast manner. Sit back and relax.

That's it! You're done.
