"Delivers a thorough explanation of VTubers, though the title is slightly vague and the video includes some fluff."

AI Summary

This video explains what VTubers are, how they work, and why people become them, using Kizuna AI as a case study. It covers the technology behind 2D and 3D models, the reasons for becoming a VTuber, and the personal stories that make the community special.

[00:04]
Kizuna AI: The Grandmother of VTubers

Kizuna AI is a Japanese VTuber who popularized the virtual creator trend in 2016, coining the term 'virtual YouTuber'. Her character lore is that she is an AI, but she is actually performed by a real human, which is the foundation of how VTubers work.

[01:10]
What is a VTuber?

A VTuber is a content creator who uses a virtual avatar, typically created with motion tracking technology. VTubers can be 2D or 3D, and they are not necessarily content creators; they can also be used for other purposes.

[01:49]
2D vs 3D VTuber Models

2D models are hand-drawn and rigged in Live2D, using layered images to create movement. 3D models are created in 3D software and rigged with a skeleton, allowing for full body tracking. 2D is more common and cheaper, while 3D offers more immersion.

[02:30]
How VTuber Tracking Works

VTubers use tracking software like VTube Studio, which tracks facial movements via webcam or phone, applying them to the model. 3D models can also use full body tracking with additional sensors.

[05:12]
Reason 1: Freedom to Be Anything

VTubers can choose any appearance, from anime girls to animals, and even create backstories (lore). This freedom allows for creative expression and personal branding.

[06:36]
Reason 2: Anonymity with Branding

VTubing provides privacy and protection from stalking and harassment while still allowing creators to have a recognizable brand and face for their content.

[07:43]
Reason 3: Overcoming Disabilities

VTubing allows people with disabilities or health conditions to pursue their dreams and connect with others. Example: Ironmouse, who has CVID, uses VTubing to live a fulfilling life and has raised over a million dollars for charity.

[11:33]
The Real Meaning of VTubing

VTubing is not just about escapism or roleplay; it's about giving people a chance to live life on their own terms and tell their own stories, even if through a virtual body.

VTubing is a unique blend of technology and personal expression, offering privacy, creativity, and opportunity. Behind every virtual avatar is a real human with a story, and the community is built on these shared experiences.

The Real Meaning

Summarizes the core message: VTubing is about living life on your own terms.

11:33

[00:04] the internet thinks. This is Kisuna, a Japanese VTuber. In fact, she's regarded by many to be the grandmother of all VTubers, the OG. She was the first to really popularize the entire virtual creator thing all the way back in 2016,

[00:17] 10 years ago. Like, she literally coined the term virtual YouTuber. >> And now she's in Fortnite. Yeah, that's actually kind of crazy, bro. So, what did I mean earlier about her being an AI? Well, it's because her character

[00:32] story is that of an AI, an artificial intelligence, real breathing flesh and bones human performing her. However, that decision

[00:44] to make her an AI was keeping the real human behind the scenes, well, that's the very foundation of how VTubers work even to this day. If you've been around VTubers long enough, her name and that iconic headband might ring a bell. But

[00:57] if it doesn't, great, because that's exactly why this video exists. So, if exactly why this video exists. So, if Tisuna I isn't well AI, but is actually a VTuber, then what is a VTuber and why do so many people want to become one? My

[01:10] VTuber guides, speaking from my own experiences. Let's get into it. So, WTF experiences. Let's get into it. So, WTF is a VTuber, and why on earth is Kizuna Eye now in Fortnite? Well, first of all, Kisuna Eye is in Fortnite because Epic

[01:24] Games is adding her in as a skin. Yes, I'll be getting this skin and no, you can't stop me. But kind of like how you become a character in Fortnite by become a VTuber character through the use of motion tracking technology. And

[01:37] the cool thing about this is that whilst many are content creators, being a VTuber doesn't always mean that you have to be. You'll see what I mean in just a bit. The virtual avatars or VTuber models are commonly found in the wild as

[01:49] two main types: 2D and 3D. Depending on what's chosen, the type of content could are by far the most common. Popularized by large VTuber agencies like Hol Life and Nijis Sanji for their eyegrabbing

[02:02] made is really interesting. 2D V YouTubers are meticulously handdrawn layer by layer by a skilled artist, then brought to life by a rigger in Life 2D. car, then the rigger's job is to engineer it so that it actually runs.

[02:17] they're in charge of making the static images move by twisting and turning and warping every layer to create the illusion of movement in 3D space, fooling your brain to seeing more of a person rather than just artwork. Once

[02:30] Vtuber, the person behind the camera. The finished VTuber model is then imported into the tracking software like Vub Studio, now allowing for a real human to perform as the character. And the way it works is that V Studio tracks

[02:43] visual feed from your webcam or your phone. It detects your face, puts a bunch of tracking points on it, and then uses that data to make the character act uses that data to make the character act shocked, smile, or bombastic side eye.

[02:56] have more freedom with the art style, and they don't require as much extra equipment like 3D does. The model you get can then be used wherever and however you want. Be it for YouTube videos, streaming, or even just hanging

[03:10] out online on Discord, or on VOC chat. For many, this is basically their face on the internet. That being said, if you noticed, her model Kizuna I doesn't actually look 2D. Well, that's because she's actually 3D. So, how are those

[03:23] from 2D? In terms of the creation process, 3D VTubers are actually quite similar to 2D. A reference sheet is drawn, handed over to the 3D artist, who then makes and paints the model before handing it over to the rigger. But

[03:36] unlike life 2D rigging, the 3D rigger basically just gives the model a skeleton. It doesn't need to be warped and deformed because it's already in 3D. the Vtuber, who also uses tracking software. However, the key difference

[03:50] here is that 3D models also allow for full body tracking instead of just facial tracking. Extra sensors are put on key points of the body which lets the BTubers do stuff like this. >> Yeah.

[04:02] >> I mean, I'm wondering if is still gonna be feeling as confident [cheering] as you mentioned during that interview. Maybe so >> pretty cool, right? And that's exactly what people love about 3D. Even though

[04:17] it's more equipment heavy and maybe a bit more expensive, it really allows you to embody your virtual self and interact with these cool, awesome virtual worlds. Okay, that explains virtual models and how they're made. Great. But why do

[04:31] people even want to become YouTubers in the first place? Aren't they like cringe and weird and only used by 40-year-old overweight weebs with neck beers and a voice changer? Well, I'm sorry to disappoint you, but

[04:44] that's not the case. though I can see why it might be cringe to some people, especially for those who are not in the know. And honestly, I don't really blame you. It's basically a whole other crazy world. But I hope that listening to this

[04:57] help give you a little bit more understanding. And hey, if you still then fair enough. I appreciate you hearing me out either way. So, with that said, here's three big reasons as to why people become YouTubers. Number one, we

[05:12] can be whatever the we want. The first point is probably the most obvious. We're using virtual avatars to represent us online. And because it's all virtual, we can basically choose whatever the we want. You want to be a

[05:24] cute anime girl? Sure, go ahead. You want to be that one meme dog with a long you. >> Let me do it for you. >> Or how about a lime? The point is, you are given the freedom to be

[05:38] whoever or whatever you want. Some even go as far as to create backstories for call Vtuber lore. This is the reason why Kisuna is an AI because that's her lore.

[05:50] And for those who take the more business approach, the lore basically serves as sharks that hail from Atlantis. Some are sentient beings made out of soup. And I'm a bird who got struck by lightning and lost his wing. [music]

[06:08] always have to play your character to a tea. In fact, you're never really obliged to, and most people, including myself, just act and talk like how they when YouTubers create their characters, there's a tendency to sprinkle in a

[06:22] designs. It could be their sense of style, an accessory, or even a personality trait. And this is why VTuber models can be a very, very personal thing to someone. And speaking of personal, let's talk personal privacy

[06:36] because that's a big reason as to why people become YouTubers in the first place. Anonymity, but with branding. Being a creator online can be really cool. But the problem is that the more popular you get, the more you attract

[06:49] certain types of strange and unique individuals, to say the least. In some cases, this could lead into things like invasions of privacy, stalking, and IRL harassment. your personal life becomes a target to those with bad intentions and

[07:03] or unhealthy obsessions. So naturally, the solution would be to go faceless, right? No face, no problem. Well, sure, but now you're just another faceless channel amongst the sea of other faceless channels. You need a way to

[07:16] stand out. And one way to do that is to create a brand. There's that term again. But do you see where I'm going with this one? Having a because now the audience has a face to attach [music] to the content. YouTubers

[07:29] basically have the advantages of high levels of privacy whilst still being recognizable to their fans. >> Wait a minute, who are you? >> And whilst Vtubing can prove as a solution to dangers like stalking, it

[07:43] unfortunately can't cure illnesses. But what it can do is give people another opportunity to achieve their dreams and live a life that they otherwise couldn't. Which brings me to point number three. We won't let disabilities

[07:55] stop our dreams. It's an unfortunate truth that not everyone in the world is in good health, nor do they have access to healthcare. There are some out there who have passions, dreams, and aspirations that were crushed due to

[08:07] medical conditions that were out of their control. That's just the unfortunate fact of life. It kind of sucks sometimes, but it doesn't mean that it has to stay that way. With enough passion and stubbornness, people

[08:20] will find a way to continue pursuing the things that they love doing the most. Even if that thing is just to live life like a normal human being. And if you can't do that in real life, then the next best place is the virtual world.

[08:33] Take Iron Mask for example, one of the biggest YouTubers on the planet right now and my personal favorite, or Kamioshi as we YouTubers like to say. Her personal story broke as many hearts as it has touched. She used to be an

[08:45] opera singer in training, but her dreams of the opera were taken away from her by CVID, common variable immuno deficiency. I'm no doctor, so I'll let Mousie >> What is your condition? I have a condition called CVID. It's called

[08:59] common variable immune deficiency disease. Uh, it means that my body does not make enough antibodies to fight off viral infections, bacterial infections, can't fight off viruses, can't fight off bacteria. So, I need to get donated

[09:12] plasma in order to have a functioning immune system. I need to get a donated immune system. Basically, I don't make antibodies. So, donate plasma if you >> If you're wondering why her voice is so high pitched, it's because her medical

[09:25] condition literally up her voice. It wasn't her choice to sound this way. Vtubing has given Iron Mouse a way to connect to the world, make friends, and make memories to continue living a life instead of just existing. The view of

[09:40] right? >> Yeah. >> it's okay. Look how beautiful the view is. >> I'm glad I could see it like this. At least

[09:52] it in person, too. >> I hope so. One day. It's just nice that there's so many of us like [music] me that can't go out and see stuff like this. And it's nice that we can see it. >> It's okay. We'll get to see so many more

[10:05] in [music] person. I'm sure we'll get to see some cool things. I would have never been able to see any of this stuff if I would never start YouTube. >> Yeah. >> That one decision you made to try it out

[10:17] you get to see the world. You get to see all these cool things and go all over I think that's [music] pretty amazing. >> And I'm glad that we met with friends. >> A going to make me cry. Me [music] too. You know that if if I had met you, I

[10:31] >> Yeah. >> Damn. Isn't that cool? [laughter] Haha. And through V tubing, she got help with funding her treatments, gradually got better over the years, and with the help of her loving community, even helped

[10:45] raise over a million dollars for the charity that provided her with crucial support when she was first diagnosed, the immune deficiency foundation. Vubing pursuing her dreams as an opera singer. Maybe not in the way that she initially

[10:59] envisioned, but through a new path that she and her precious family has carved out. >> [music]

[11:33] miss and subsequently never realize is that it's not always about escapism, roleplay, or being a cute anime character online. It's about being given a chance, a chance to live a life on your own terms and experience a world

[11:49] that you were never really able to. Everyone's lives are different, unique, and special. Everyone has their own story to tell. And the beauty about V tubing is that it gives you the opportunity to tell your own story in

[12:03] whatever way you want. So when people say that Kizuna Eye is AI, they are wrong, but they're also accidentally pointing towards something real just hidden away. Behind all of that lore, behind the virtual model and behind the

[12:17] behind the virtual model and behind the computer screens are real humans telling computer screens are real humans telling their own stories [music] just through a virtual body. So, let me ask you this. Did this video help you understand what

[12:30] become one? Are you interested in becoming a VTuber even? Do you have a story that you want to tell? Chiao.
