YouTube videos can be embedded in your idea by pasting video link in Idea description or Idea comment.

IdeaScale will automatically render the video clip inline in the idea as shown below. 

Also you can set up set up the custom field called "YouTube Video","Screen Video" or "HapYak Video" from the Community Settings >> Workflow>> Idea Submission>> Idea Custom Fields so that community members can paste in a YouTube, Screen or HapYak video link within the custom field of an idea. However streaming of video in custom field is not supported.

Hosted video from other online services may also be supported. Contact your account representative to learn how to add your preferred video service to IdeaScale.
