Online companies partner on wedding video services March 2nd, 2012 None of life’s milestones generate more footage than nuptials, and the volume of video only promises to grow now that every wedding attendee can pull out a phone or camera to record the moment. The popularity of video pushed two area web-based companies to work together to offer marrying couples ways to manage, use and share the clips of their big event. Mywedding LLC, a popular online wedding-planning and advice service based in Castle Rock, is adding several online video services for newlyweds, which are powered by Pixorial Inc., a Centennial startup with 16 employees. Pixorial helps people put video online — a lot of which it transfers from customers’ analog home movies — and then store, edit and share it. Pixorial users bring it more wedding footage than anything else. Given that weddings often lead to those other major video moments — childbirth, kids’ birthdays, first steps, school plays, sports, graduations — Pixorial sought a partner that could help the company gain exposure with couples from the start, said Andres Espiñeira, its founder and CEO.
