In SMG4's videos, bloopers are remotely different from most other machinimist's bloopers, as they contain inappropriate, strange, and insane jokes that could easily be dubbed non-canon to other videos. The videos are also mistaken by fans to be the inspiration for numerous other successful machinimists who came before them when some videos weren't based on them at all. SuperMarioGlitchy4's videos also include small crossovers with TV shows (e.g. Teletubbies) and a few other video game franchises (e.g. TF2).
The method that SMG4 uses to edit his bloopers has changed over the years. Here, you can see his progression:
Early-Mid 2011: The audio of recorded SM64 clips used for the bloopers was present, which made the in-game music play over it. Subtitles here were outlined with simple lines and lasted for exactly 3 seconds.
Late 2011/Early 2012: By this time, the evidence of SMG4 using Sony Vegas gradually increased due to the presence of picture movements and text presets from the videos during this period. The recorded audio was removed. Profanity use and mature content also began to increase by this period.
Mid-Late 2012: New fonts for the subtitles were launched, such as Verdana, and the format of SMG4's bloopers by this time were shot to complete 4:3 stretch to widescreen.
2013/Early 2014: During this period, SMG4's bloopers became more wild and ditzy. The first use of the word "swag" was also present; the characters gained eye expressions, and their heads no longer moved while idling. The Super Mario 256 font also began being used as well.
Late 2014/Late 2015: Verdana and Super Mario 256 are no longer used majorly, with Sony Vegas text presets and Arial in their place. This isn't the first time SMG4 used these fonts (see Late 2011/Early 2012). The emotion and mood are still present. True, unstretched widescreen started being used in a few videos by this period before eventually becoming permanent from "SM64: ṩṩἔᾗмὄḋᾗᾄʀ 9 - Time travel edition". In 2015, the Super Mario 256 font was reintroduced in a few bloopers, though not used under the 2013/Early 2014 style, instead having the same type of outlines as the dialogue text. Since War of the Fat Italians 2015, a font similar to Super Mario 256 but with lowercase letters, known as Super Mario 286, has been used permanently for the dialogue text. This is currently SMG4's longest used style of bloopers since the previous one.
End 2015/Early 2017: The Project64 screen is used in 4:3 stretched widescreen and the resolution is now in HD. Around Late 2016, SMG4 is stopping to use Arial font's not counting the Super Mario 286 font that he already used for the speaking font’s in the characters.
