THE 1 SECOND THAT DECIDES IF YOUR VIDEO GOES VIRAL

Summary from the TLDR Marketing newsletter

Most captions are added as an afterthought and miss what holds attention. The first subtitle should appear at second 0 and stay under 6 words. Key phrases should be enlarged 1.5 to 2X for emphasis. Background contrast like a semi-transparent bar or drop shadow improves readability. Platform auto-captions should be turned off to avoid duplicate text. Subtitles should sit within the middle 60% of the frame to avoid TikTok, Instagram, and LinkedIn UI overlays.
