The Base64 Email Overhead Trap
Email protocols (MIME) encode binary video files as plain text via Base64, inflating attachment weight by ~33%. Keeping your raw export file strictly at or under 20MB guarantees that Outlook and corporate Exchange firewalls will never reject your email.
Universal Compatibility
Always export using the H.264 video codec and AAC audio in an .mp4 container. This guarantees your video will play natively inside Outlook, macOS Mail, iPhones, and Android without requiring third-party players.
