Notes
Height = width × 9 ÷ 16. A 1920-wide frame is 1080 tall. A 1280-wide frame is 720 tall.
YouTube encodes 16:9 cleanly. Pillarbox only appears if you upload a taller ratio without letterboxing yourself.
Thumbnails are 16:9 at 1280×720. Design titles in the center third so mobile crops still read.
