Resolution and aspect ratio
YouTube uses 16:9 aspect ratio players. If you’re uploading a non-16:9 file, it will be processed and displayed with either black bars on the left and right (pillar boxes) or black bars at the top and bottom (letter boxes) to make a 16:9 ratio in the player.

Learn how to use resolution and aspect ratios correctly.

Learn how to use Spatial Audio , 360 video, and virtual reality video so your viewers can experience your video’s sound in all directions, just like real life.
