Great question! To make a video, you'll need recording equipment and an application such as Lightworks, iMovie, or Adobe Premiere. (As a student, you have free access to Adobe software, which you can request at http://links.asu.edu/adobestudent.)
To create a podcast, you'll need recording equipment, an application like Audacity or Garage Band, a hosting platform such as Anchor or Podbean.
You'll also need recording releases for anyone appearing in the podcast.
