Best codecs for sharing videos

For sharing videos on mobile devices, MP4 with H.264 codec and AAC audio is the best overall format. It offers the ideal balance of high quality, small file size, and universal compatibility across smartphones, social media platforms, and web browsers.

• Why MP4 (H.264): It’s supported by virtually all mobile devices (iOS and Android), social media apps (Instagram, TikTok, Facebook, YouTube), and streaming services. It ensures smooth playback without compatibility issues.
• For high-resolution content (4K): Use MP4 with HEVC (H.265) for better compression and smaller file sizes, especially on modern devices like iPhones and newer Android phones.
• Avoid outdated formats: 3GP is suitable only for very old phones or low-bandwidth environments; it offers poor quality and is not recommended for modern mobile sharing.
• Best export settings for mobile:
  • Resolution: 1080×1920 (vertical for Reels/Stories)
  • Frame rate: 30fps
  • Bitrate: 5–8 Mbps for standard quality, 35–45 Mbps for 4K
  • Format: MP4 with H.264 or HEVC

This format ensures fast uploads, efficient streaming, and consistent playback across the wide range of mobile devices used today.
