Key takeaways
  • Vertical video (9:16) captures 100% of mobile screen real estate and commands 4x higher completion rates than landscape videos.
  • Keep crucial text and graphic elements inside the 'safe zone'—avoiding the top 15% (header) and bottom 20% (caption overlay) of the screen.
  • Over 75% of social video is consumed with the sound muted; accurate burned-in captions are mandatory for retaining viewer attention.
  • SEO Runway's media composer validates video file sizes, bitrates, and aspect ratios prior to network API submission.
If your video forces mobile users to rotate their phone to watch it, 80% of them will simply scroll past. Build vertical-first.
