The channel, which is due to launch in July, aims to become a "hub for high-quality, high-impact investigative videos" and is backed by $800,000 in funding from the Knight Foundation.
It is a partnership between the Center for Investigative Reporting and the Investigative News Network, who will work together to promote the channel and to engage users through social media and online chats.
The channel will feature videos from major broadcasters - including NPR, ABC and the New York Times - and will also seek contributions from freelance video journalists and independent filmmakers around the world.
The CIR said in a release that journalists would be trained in audience engagement and other best practices for online video. Revenue from the channel will be used to subsidise public interest journalism projects.
The centre's executive director Robert Rosenthal said: "One of the goals of this partnership will be to raise the profile and visibility of high-impact storytelling through video.
"We hope this initiative generates revenue that supports the work of nonprofit organizations and independent filmmakers everywhere. Collaborative efforts like this are no longer the future of journalism; they are today's reality."
Knight Foundation vice president for media innovation Michael Maness added: "This collaboration is poised to bring investigative reporting authoritatively onto the social web. We hope it will engage audiences and expand public appetite for visual storytelling."
The Center for Investigative Reporting was founded in 1977 and has produced stories for outlets including NPR, PBS, the Los Angeles and New York Times, Washington Post and San Francisco Chronicle. The Investigative News Network represents 60 not-for-profit newsrooms around North America.
