Frame rate
Content should be encoded and uploaded in the same frame rate it was recorded.
Common frame rates include: 24, 25, 30, 48, 50, 60 frames per second (other frame rates are also acceptable).
Interlaced content should be deinterlaced before uploading. For example, 1080i60 content should be deinterlaced to 1080p30, going from 60 interlaced fields per second to 30 progressive frames per second.
Bitrate
The bitrates below are recommendations for uploads. Audio playback bitrate is not related to video resolution.

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.
