Reduct makes the process of reviewing research footage very easy.
If you'd like to pull in study sessions from UserTesting click the "Import from web" button in your project.
That modal will show you a field where you can paste a link to your UserTesting video(s).
Once your test is published you can paste a link to the published page or to a single video from there to get that content uploaded. For a step-by-step on how to publish a test visit this help article on UserTesting.
