Videos sent via email and social media are nothing new, but now there's a way to send videos alongside physical, paper invitations via Engaging Invites. Each 5- by 8-inch invitation includes traditional printed copy designed by the bride and groom on the left side plus a seven-inch LCD video display and built-in speaker on the right. When the invitation is opened, the custom video, lasting from 30 seconds to three minutes, automatically plays. Engaging Invites start at $38 each for 500 or more. Assistance with design and video production is available for an additional fee.
