1What the pages say

Sora's guide names sizes rather than tiers: 1280x720 in its examples and 1920x1080 or 1080x1920 on sora-2-pro. Both models support 16- and 20-second generations. The guide says nothing about marks on the file.

Maximum resolution: 1080p

Use sora-2-pro when you need 1080p exports in 1920x1080 or 1080x1920 .
