1 Import the video to this video resize for Mac

To start working with this video editor on Mac, download and install the software on your computer. Then go to Import and select your video file from the media browser to add it to the program. You can also directly drag and drop your video file to the timeline.

2 Start resizing video size in Mac

If you want to resize the aspect ratio of the video, highlight the target file and right-click Crop and Zoom. In the pop-up window, then you can manually customize the marquee or keep the marquee in 16:9, 4:3, 1:1, and 9:16 aspect radio according to your desire.

3 Export the new video

Then hit the EXPORT button in the toolbar. In the Local tab, choose from a list of video formats that your video file can be converted to. By converting, you can easily get a new video file in a different size. But if you want to keep the original video format, just click SETTINGS to adjust the output options such as Resolution, Bitrate, and Frame Rate to resize your video.

After that, name the new video file and select the directory where it will be created as well. Then hit EXPORT and the program will begin resizing the video file. This process may take some time depending on the size and the selected options. When the process is completed, find the folder containing the file. Right-click on the file and click Properties. Look for the size of the new file. It should be different from the original file.
