Video Letterboxing
Letterboxing is the practice of adding black bars at the top and bottom to change the aspect ratio of a video, while preserving the aspect ratio of the original video.
Why do we test it?
Letterboxing is not appreciated by most publishers, as it's not a great user-experience, nor does it use make full use of the ad unit's available space.
