include the flag (CTF), only two colors could be used (Sarge's and early Donut's red, and Caboose's blue) as CTF is a team game and only red and blue colors could be used. When the flag used among different colored characters, it is only shown with a standard red or blue character, mixed with scenes with other characters behaving as if it is present. During recording, there was an issue with the Blue Team's deceased leader, Church. Church appears as a ghost for some parts of the show, and he needed to appear transparent to the viewer. To achieve this, all scenes with ghost-Church had to be recorded twice, once with Church in them and once without him. After the switch to Halo 2, Church's ghost form was portrayed using the "Poor Camo" Armor enhancement. Another difficulty when recording in Halo 2 was the enormous shadow over Red Base in the map Coagulation. This shadow had a detrimental effect on the appearance of the characters. To avoid this, late in Season 4 a glitch was discovered that allowed a character to appear lit even in a dark area. Burnie Burns stated in the Season 4 audio commentary that the glitch was something they kept noticing a lot while recording the episodes, and when they discovered how to replicate it they utilized it extensively. During the first five seasons, the videos were mostly recorded on the Halo map Blood Gulch and its Halo 2 counterpart, Coagulation, although later episodes have increasingly been recorded on other maps. Episodes that have been made with the games starting with Halo 3 have used the theater mode camera. The Forge Mode from Halo 4 onward also helped by providing a green screen and the creation of entire areas for certain scenes. Starting in season 8, action sequences have been made with dedicated animation that involve stunts not possible with the previous game engine. For this, they teamed up with animator Monty Oum, a fan of the series. Making the show more ambitious and reliant on computer animation led to extensive planning – fight choreography, storyboards, animatics – for episodes that take months to be completed, in contrast to machinima ones that are done in just a week. Post-production Adobe Premiere Pro is used to edit the audio and video together, add the titles, and create some of the special effects not normally possible on the
