The Secret Behind BFB's Split is a video on jacknjellify that premiered on March 28, 2020 at 9:45 a.m. PDT (16:45 UTC). The video explains the reasons behind why the crew made the decision to split Battle for BFDI into two shows and also address common questions and criticisms on the split as well. The thumbnail shows Cary Huang, and an angry Four pointing at Two, both of the latter's poses being taken from "The Escape from Four".
The twins explain that during the progression of the episodes, the standards on the quality of their animations became way too high for their liking, and whenever they look at old BFDI episodes, they see a kind of "magic", because when they made those episodes, the quality was really low, they liked to goof-off with the storyline, and it was spontaneous.
So, it was for this reason why they decided to make BFB, originally called "Sloppy BFDI", with the intent of releasing an episode every few days while keeping animation expectations low. They intended on returning to the "fun" they had during the making of the original BFDI. However, the twins explained as that season progressed, they realized that their expectations for the animation quality began to rise once again, especially in 2018 and 2019.
Cary explained that he and Michael realized the two main elements of an object show that people are expecting: goofy spontaneity, and extremely polished animations with long storylines and extremely qualitative character development; "the pinnacle of what the object community had to offer." He further explained that both of these elements are very different, and how they struggled to successfully fulfill both in any sufficient capacity. Cary explains that this is where the split in BFB comes in. The twins wanted a show where they could go back to a fun and carefree animation style, BFB, while saving The Power of Two, for the more "qualitative" animation style.
Going further into the future of their show, Cary also explains about what could happen once BFB ends. With the end of BFB, the twins can go on to try new styles of animation, which they said give them more freedom. "So, long story short, this split was to give more people what they want."
