Fill Frame on the sides - Guided Edit
This Guided edit is a walkthrough on how to fill in the black bars around the video to match the video frame.

You might have often seen black bars on the sides of your pictures or videos. This happens when the aspect ratio of media is different from the aspect ratio of the PRE project. This can often make your output look unappealing. Use the Fill Frame feature to fill the bars around your pictures and videos to match the video frame.
