I will convert vertical video to horizontal format

Solution 1: Add A Blurry Background

If you would like to keep the image quality of your video clip, then I'm going to create a blurred background for your vertically oriented video.

Solution 2: Cropping

Cropping is a common way to convert vertical videos to horizontal format. If you choose to use this method be aware that you'll lose around two-thirds of the shot and some image quality.
