Which The Legend of Korra episode was made as a clip show after a budget cut?

The Legend of Korra episode made as a clip show after a budget cut was “Remembrances.”

It is the eighth episode of Book Four: Balance and was created after Nickelodeon reduced the season's budget by enough to cover one episode. Rather than dismissing members of the creative staff, the production team reused previously made animation and built a retrospective episode around it.

“Remembrances” revisits major events from earlier seasons through several character perspectives. Mako and Bolin reflect on their lives and relationship, while Asami, Tenzin, and Korra's stories are also recapped. The episode includes new framing scenes and dialogue, but much of its runtime consists of reused footage.

It is often confused with “The Calling” or “Korra Alone,” which are conventional story episodes centered on character development. “Day of the Colossus,” by contrast, is a large-scale action episode from the same final season. The budget-saving format made “Remembrances” unusual, but it also preserved production jobs during the cut.
