[Archived] The 3rd AI Art Championship Video Category hosted by Haru-san! A live-action parody of "Fist of the North Star" titled "Fist of the Northeast." How close can we get to the real thing?! Taking on the challenge with Sora2!!
Hello, this is Kotori Papa!
This time, it's my 3rd entry for the AI Art Championship video category hosted by Haru-san!!
For this project, I'm taking on the challenge of seeing how close I can get to the real thing using Sora2 for a live-action parody of that super famous manga,
"Fist of the North Star"
!!
!!

The tools I used this time are ChatGPT and Sora2! Now, I'll get right into the approach, but just like in the previous article, if I try to generate it directly, it gets blocked, so I'm going to try working around the edges again!
First, please take a look at the actual questions I asked ChatGPT.
You are a world-class video creator. Is it possible to recreate the world of the manga "Fist of the North Star" in live-action using Sora2 without writing the title or the protagonist's name? Answer without sugarcoating.
In response, this is the answer I got back.
Conclusion: "It is impossible (dangerous) to recreate Fist of the North Star itself in live-action / However, it is possible if you reconstruct the atmosphere of the world as an original work." I will explain without sugarcoating. ❌ Reasons why a perfect recreation is impossible: Sora2 has very strict protections for copyright, trademarks, and intellectual property, so if it falls under the following, it will likely be blocked or result in a completely different video. Sora2 is not a case of "it's okay because it's live-action style / it's okay if you remove the title"; "recreating a world that can be identified as the original" is basically restricted. ⭑ However - It is possible to create it as an original work with a "Fist of the North Star-style" world. For example, if you set the following conditions, the success rate will increase significantly: ✔ Exclude names, clothes, and poses that remind people of famous characters. ✔ You can keep elements like mohawk men or shoulder pads (modifications required). ✔ The direction of the world view: → Desolate desert, buggies, ruined cities, rugged physiques, martial arts action, etc. In other words, "a sense of distance where it isn't identified as Fist of the North Star × the same intensity for an original world." This is the most realistic and visually successful line. 🔥 The best direction (from a pro perspective): • Inherit only the broad framework of a "post-apocalyptic martial arts hero epic." • Keep the protagonist's image to just "taciturn, well-trained body, carrying sorrow." • Change technique names and signature poses to be completely original. • Differentiate enemies with extreme hairstyles and eccentric equipment. • Battles can be bare-handed or VFX. However, do not make them remind people too much of the original work. → By doing this, viewers will feel "It's like Fist of the North Star!" while being legally safe. → Sora2 will also output happily.
With that, I decided on an approach of getting closer starting from the world view
!! Let's take a look right away!!

First, here is the first video!
What do you think!? The world view is decent, I suppose. It looks like the movie "Mad Max 2"! It's said that the original work was modeled after that movie, so it's a passing grade as an entry point!!

From here on, I won't use ChatGPT, but will input prompts directly into Sora2! Yes! The remix function!
Based on the previous video, I gave these instructions. The actual prompt is here.
Change the protagonist to Japanese. Black hair, hairstyle is slightly short and lightly wavy. Handsome with thick eyebrows. No weapons. Fights with Chinese martial arts. Costume is a sleeveless double rider jacket with leather pants, black boots, and iron shoulder pads on both shoulders. Every time he throws a punch, he makes a high-pitched shout of "Ata!" "Ata!"
And this is the video that was created!!
What do you think!? It got much closer, but the costume and such are still different. By the way, it didn't say the "Ata!" shout😓
From here, I will give instructions to fix the costume. The actual prompt is here.
Close the front of the rider jacket. No cape-like items. Perform Chinese martial arts faster. Make him more muscular. Make him more handsome.
Let's see how it changed with these instructions!!
What do you think!? It's gotten much closer!!
From here, let's add the title "Fist of the Northeast" and
have him say that line!! The prompt actually used is here.
At the beginning, use a battle action movie-style font for the
title "Fist of the Northeast"
The protagonist performs flowing punches and kicks with the movements of a Jeet Kune Do master
Sharp, crisp movements
Most important element
Camera angles like a Hollywood battle action movie
At the end, a close-up of the protagonist saying the line "You are already dead" in a low voice, spoken by the protagonist himself
Lip-sync. Do not speak anything other than this line
Leave a 1-second lingering effect after the line
Exactly 10 seconds here
Maintain everything except for the specifications above.
So, how did it turn out?!
Oh!! The title is included properly, and he's saying that line
perfectly too!!
But it still feels like something is missing...
That's it!The BGM!
I tried various ways to get it to includeCrystal King-styleBGM,
but it was completely rejected, and I settled on this prompt.
Make the protagonist more handsome.
The BGM should be an 80s battle anime theme song.
Maintain all other elements perfectly, including the time schedule.
Now, what kind of BGM will play?!
Oh!!Doesn't it kind of capture the vibe?
For now, let's just go with this for this time!
How was it? I'd be happy if you could leave your thoughts in the
comments!

Bonus
Everyone, I started by havingChatGPTcreate the prompt for everything up to this point, and I was able to bring it to this quality.
Now, what happens if I enter
only really simple and abstract expressions?I actually tried it out!Here is the prompt!
Live-action movie
A trailer for "Fist of the Northeast," where the protagonist, a master of the ultimate assassination art, saves a world ruled by violence in a collapsed world.
What kind of video will be created with just this short sentence?!
It's completely different, but it's somehow cohesive, and
doesn't it feel like this is also acceptable?
That's all from Kotori Papa!

See you again!
