Black bars on videos

You may notice some widescreen videos that have black bars on all sides. Here’s why this formatting may appear:

  1. The video file includes horizontal black bars (letterboxing) at the top and bottom of the video player in order to fit a 4:3 aspect ratio.
  2. Our 16:9 aspect ratio player then adds vertical black bars (pillarboxing) to fit a 4:3 formatted video to YouTube player dimensions.
  3. The end result is black bars all around the video (windowboxing).

If you’re uploading widescreen videos, you can avoid windowboxing by cropping your video to the 16:9 format.
