One thing that they kind gloss over is that rotoscoping is used a lot in films to separate objects. For example, I did an exam on prince caspian (https://eu.southcoasttoday.com/story/entertainment/local/2008/05/15/prince-caspian-improves-on/52409998007/ https://eu.southcoasttoday.com/story/entertainment/local/200...) to separate his hair from the forest. They didn't have green screen, and even if they did, it would obliterate his hair. (hair is translucent so glows green, and is removed by the software.) I failed the rotoscoping part, but passed the painting section (where you remove markers, crew or other features not wanted in the final image.) Whilst "a scanner darkly" is a brilliant example of rotoscoping, its not the example. if you look at this showreel towards the end you see captain marvel, https://www.youtube.com/watch?v=_sYWzFNobEo https://www.youtube.com/watch?v=_sYWzFNobEo look at her hair, every individual wisp of hair that extends past her neck is individually masked out. Good rotoscoping is often the building block of "expensive" looking VFX. For computer vision its also important so you can get ground truth on tracking various object and training models like segment anything
