continued to provide music for the show from their second and third albums, Ghosts That Linger and Flying by Wire. Beginning with Red vs. Blue: Revelation, the main score for each season has been crafted by Jeff Williams, the former keyboardist of Trocadero, in addition to many of Trocadero's songs being reused. Williams's soundtracks have genres containing mixed elements of score music, hard rock, and sometimes electronic and rap. Williams often features others on vocals including Lamar Hall, Red Rapper, Barbara La Ronga, Nicole D'Andrea, his daughter Casey Lee Williams, Sandy Lee Casey, and some members of the cast, and collaborates with Steve Goldshein on some tracks. The soundtracks also feature several parody songs, and some songs included are heard in PSAs and Rooster Teeth shorts.

Trocadero returned as the sole-provider of Red vs. Blue's score for the first time since season seven, also providing a new theme song "Contact" effectively replacing "Blood Gulch Blues". David Levy joined the music team alongside Trocadero in season 13 and has continued to write music for the show since.

The camera is simply another player, whose first-person perspective is recorded raw to a computer. The Apple Macintosh games Marathon and Marathon 2: Durandal were also used in Season 3 for scenes that occur in the distant past; this has the effect of making the graphical quality of the series an indication of time's progression throughout the story. The first five seasons of Red vs. Blue were later reshot in high definition using the PC ports of Halo: Combat Evolved and Halo 2, which have also been featured in later seasons whenever those games were required. In the interview on The Screen Savers, Burns described the use of machinima techniques to record the show thus: "It's like normal animation but instead of, y'know, sitting down, drawing everything by hand, we just use
