Frame rate

Content should be encoded and uploaded using the same frame rate that was used during recording.

Common frame rates include: 24, 25, 30, 48, 50 and 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.

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 correctly as well, with pillar boxes (black bars on the left and right) or letter boxes (black bars at the top and bottom) provided by the player.

Learn how to use resolution and aspect ratios correctly.
