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.
