Premiere Pro allows you to add special effects to your video projects, such as transitions, titles, credits, and rotation. The most common way to rotate a video is by using the Transform effect. This effect lets you change the orientation of a clip. Using this effect, you can create cool visuals or fix angle issues that your clip might have.
PS: The process is exactly the same if you're using Adobe Premiere Pro CC's lighter version, Premiere Rush.
