Multi-Platform Video Strategy

Creating Videos for Multiple Platforms

  • Master in 16:9: Create your main content in 16:9 for YouTube, then adapt for other platforms
  • Safe Zones: Keep important content in the center 80% to allow for cropping to different ratios
  • Vertical Versions: Film separate 9:16 versions for Shorts/Reels rather than cropping horizontal video
  • Template Approach: Use editing templates with guides for different aspect ratios
  • Export Multiple: Export different versions optimized for each platform's requirements
