To cite a YouTube video in your references list, follow this general format:
Last Name, F. M. [Username, if different]. (Year, Month Date). Title of video [Video]. YouTube. URL
TED. (2013, 16 July). Gavin Pretor-Pinney: Cloudy with a chance of joy [Video]. YouTube. https://www.youtube.com/watch?v=lhP52caGW6s&t=340s

For in text citations:
Use the author & year format you would normally use for APA in-text citations. Since there are no page numbers, quotations and paraphrases are cited the same. For example:
Many of the early UFO pictures were actually lenticularis clouds (TED, 2013).
New studies may indicate that humans can become immune to COVID 19 (CBS This Morning, 2020).
