How I Constructed a Comedian Generator with OpenAI and Gemini

We’ve got all loved comics in some unspecified time in the future, be it superhero comedian books, comics in newspapers, or manga from Japan. Comics are temporary, expressive, and encapsulate storytelling inside just some frames.  However what if there’s a new twist: what when you might use a comic book generator to show a brief video clip into a comic book strip of 4 panels with speech bubbles, expressive caricatures, and humour?

That is the concept behind Comedian Generator or Comedian Warfare, not simply one other content material generator. Nonetheless, a system I designed that takes a video clip and a brief, temporary inventive thought and turns it right into a completed sketch picture. It’s greatest to consider it as an imaginative partnership between two minds: one “writing the screenplay” and the opposite “drawing the comedian.”

On this article, I’ll information you thru the journey of Comedian Warfare, explaining the way it works, what elements are required, which programming language to make use of for coding, the challenges I encountered throughout the course of, and the place the mission can go from right here.

The Idea of Comedian Warfare

All inventive purposes hinge on an ordinary system:

• Enter: What the consumer provides.
• Transformation: How the system operates and furthers it.
• Output: The distillation of the expertise that feels full and polished.

For Comedian Warfare, the system appears to be like like:

• Enter:
  • A brief video (like a YouTube brief).
  • A one-line inventive thought (“Substitute the combating within the clip with exams”).
• Transformation:
  • Systemically, the system analyzes the video, rewrites the concept right into a full comedian screenplay, and strictly enforces guidelines (layouts, model, humor).
• Output:
  • A 4-panel sketch in PNG format with dialogue balloons and captions. 

What makes this enjoyable? As a result of it’s customized. As an alternative of random comics, you’ll obtain a reinterpretation of the very clip you simply chosen, tailor-made round your one-line thought.

Contemplate a battle scene in a film, echoing a pupil morphed right into a goofy classroom battle about homework. This concoction of relatable visuals – acquainted usernames with a stunning, personalised comedian rewrite twist – is what makes Comedian Warfare addictive.

How Comedian Warfare Works

The pipeline is deconstructed as follows:

1. Inputs from the Person

The method begins with two easy inputs:

• Video URL: Your supply materials (ideally YouTube shorts of round 30-40 secs).
• Thought Textual content: Your twist or theme.

Instance:

Video URL: https://www.youtube.com/shorts/xQPAegqvFVs

Thought: As an alternative of violence, change it with exams, like Yash saying

“Violence, violence, I don’t like violence, I keep away from… however violence likes me.”

That is all of the consumer has to supply, no advanced settings, no sliders.

2. The Storyteller’s Job (Gemini)

The primary a part of the pipeline is what I consult with because the Storyteller. That is the place the uncooked enter of a YouTube video hyperlink and a short thought you typed in will get remodeled into one thing structured and usable.

Whenever you paste a video URL, Gemini appears to be like on the clip and extracts particulars:

• What’s taking place within the scene?
• The temper (tense, dramatic, lighthearted).
• How the characters are transferring and interacting.

Then it takes your one-liner (for instance, “change violence with exams”) and expands it into a comic book script.

Now, this script isn’t simply random textual content. It’s a screenplay for 4 panels that follows a strict algorithm. These guidelines had been explicitly written into the system immediate that guides Gemini. They embrace:

• All the time a 2×2 grid (so each comedian appears to be like constant).
• Strictly a comic book e-book model (no life like rendering of characters).
• Dialogue written as meme-like speech bubbles.
• Captions added for further punchlines or context.
• Nothing cropped, no cut-off textual content, and no dangerous references to copyrighted names.

By baking these constraints into the system immediate, I made certain the Storyteller at all times produces a clear, dependable screenplay. So as a substitute of asking the picture generator to “simply make a comic book,” Gemini prepares a completely structured plan that the subsequent step can observe with out guesswork.

3. The Illustrator’s Job (OpenAI / Imagen)

As soon as the script is prepared, it’s handed on to the Illustrator.

This half doesn’t need to interpret something; its single accountability is to attract precisely what the Storyteller described.

The Illustrator perform is addressed by a picture technology mannequin. In my setup, I’ve OpenAI’s GPT-Picture-1 as my first selection, and Google’s Imagen as a secondary fallback if the primary software fails.

Here’s what it appears to be like like in apply:

• The Illustrator receives the screenplay as one lengthy, detailed immediate.
• It then renders every panel with the characters, poses, background, and speech bubbles precisely as laid out.
• If OpenAI is unavailable, the identical immediate will get despatched to Imagen robotically, so that you at all times get a completed comedian.

This separation is the important thing to creating Comedian Warfare dependable.

• Gemini thinks like a director: it writes the script and units the stage.
• GPT-Picture-1 or Imagen, they draw like artists, they observe the directions with out attempting to vary something.

That’s why the output doesn’t really feel messy or random. Every comedian comes out as a correct four-panel strip, styled like a meme, and matches your thought nearly one-to-one

4. Output: The Ultimate Comedian

The result’s a 4-panel sketch picture:

• Panels are clearly framed.
• Characters in the proper poses.
• Speech bubbles with the proper textual content.
• Humour intact.

And better of all, it appears like a completed comedian you may be printed on-line.

Applied sciences Behind Comedian Warfare

Right here’s what powers the system:

• Language & Utilities
  • Python is the glue language.
  • dotenv for API key administration.
  • Pillow for picture dealing with.
  • base64 for processing picture information.
• The Storyteller (Evaluation + Prompting)
  • Gemini (multimodal mannequin): reads video + expands consumer enter.
• The Illustrator (Picture Technology)
  • OpenAI GPT-Picture-1 (a DALL·E variant).
  • Fallback: Google Imagen (for resilience).

This twin strategy ensures each creativity (from the storyteller) and visible consistency (from the illustrator).

Implementation

Now, let’s look into the precise implementation.

1. Configuration

@dataclass

class ComicGenerationConfig:

    primary_service: str = "openai"

    fallback_service: str = "imagen"

    output_filename: str = "photos/generated_comic.png"

    openai_model: str = "gpt-image-1"

    imagen_model: str = "imagen-4.0-generate-preview-06-06"

    gemini_model: str = "gemini-2.0-flash"

The place the fashions have been used within the following method:

• OpenAI is the default illustrator.
• Imagen is the backup.
• Gemini is the storyteller.

2. Constructing the Screenplay

def extract_comic_prompt_and_enhance(video_url, user_input):

    response = gemini_client.fashions.generate_content(

        mannequin="gemini-2.0-flash",

        contents=[

            Part(text=enhancement_prompt),

            Part(file_data={"file_uri": video_url, "mime_type": "video/mp4"})

        ]

    )

    return response.textual content

This step rewrites a imprecise enter into an in depth comedian immediate.

3. Producing the Picture

OpenAI (major):

end result = openai_client.photos.generate(

    mannequin="gpt-image-1",

    immediate=enhanced_prompt,

)

image_bytes = base64.b64decode(end result.information[0].b64_json)

Imagen (fallback):

response = gemini_client.fashions.generate_images(

    mannequin="imagen-4.0-generate-preview-06-06",

    immediate=enhanced_prompt,

)

image_data = response.generated_images[0].picture

Fallback ensures reliability; if one illustrator fails, the opposite takes over.

4. Saving the Comedian

def save_image(image_data, filename="generated_comic.png"):

    img = PILImage.open(BytesIO(image_data))

    img.save(filename)

    return filename

This methodology writes the sketch to disk in PNG format.

5. Orchestration

def generate_comic(video_url, user_input):

    enhanced_prompt = extract_comic_prompt_and_enhance(video_url, user_input)

    image_data = generate_image_with_fallback(enhanced_prompt)

    return save_image(image_data)

All of the steps tie collectively right here:

• Extract screenplay to Generate comedian to Save output.

Demo Instance

Let’s see this in motion.

Enter:

• Thought: “Substitute violence with exams.”

Generated screenplay:

• Panel 1: Hero slumped at a desk:  “Exams, exams, exams…”
• Panel 2: Slams e-book shut: “I don’t like exams!”
• Panel 3: Sneaks away quietly: “I keep away from them…”
• Panel 4: A large e-book monster named Finals: “…however exams like me!”

Output:

Challenges in Constructing Comedian Warfare

No mission is with out hurdles. Listed below are some I confronted:

• Imprecise Inputs: Customers have a tendency to provide brief concepts. With out enhancement, outputs look bland or imprecise as a result of restricted data. Resolution: strict screenplay enlargement.
• Picture Failures: Generally picture technology stalls. Resolution: computerized fallback to a backup service.
• Cropping Points: Speech bubbles received minimize off. Resolution: specific composition guidelines in prompts.
• Copyright Dangers: Some clips reference well-known films. Resolution: auto-removal of film names/manufacturers within the screenplay.

Past Comedian Warfare

Comedian Warfare is only one use case. The identical engine can energy:

• Meme Turbines: Auto-generate viral memes from trending clips.
• Academic Comics: Flip boring lectures into 4-panel explainers.
• Advertising Instruments: Generate branded storyboards for campaigns.
• Interactive Storytelling: Let customers information tales panel by panel.

Briefly, something that mixes humor, visuals, and personalization may benefit from this strategy.

My DHS Expertise

Comedian Warfare began as one in all our proposals throughout DHS, and it’s one thing very private to me. I labored with my colleagues, Mounish and Badri, and we spent hours considering collectively, tossing concepts and ideas on the market, rejecting concepts, and laughing at issues we got here up with, till we lastly discovered an thought we thought we might actually do something with: “How about we take a brief video and make a comic book strip?”

We submitted our thought, incognizant of what would occur… and we had been stunned when it received chosen. Finally, we needed to create it, every bit by piece. It entailed many lengthy nights, a lot of debugging, and loads of pleasure each time one thing ‘labored’ the best way we wished it to. Seeing our thought transfer from simply an thought to one thing actual was truthfully top-of-the-line emotions ever.

Response from Of us

What we witnessed, once we let it free, was effectively price it, as all of the responses had been constructive. Folks stored telling me it was nice, and that they had been intrigued by the concept and the method of how we arrived on the thought after which made it occur. 

Maybe essentially the most stunning half for me was how individuals started to make use of it in methods I by no means thought of. Mother and father started to make comics for his or her youngsters, actually turning mundane little tales into one thing particular and visible. Others began exploring and experimenting, considering of essentially the most superb prompts after which seeing what occurred subsequent. 

For me, that was essentially the most thrilling half, seeing individuals get enthusiastic about one thing we created after which go and create one thing even cooler, and to see this little thought second flip into one thing like Comedian Warfare was superb.

Conclusion

Constructing Comedian Warfare was a lesson in orchestration, splitting the job between a storyteller and an illustrator.

As an alternative of hoping a single mannequin “figures every thing out,” we gave every half a transparent position:

• One expands and constructions the concept
• One attracts faithfully

The result’s one thing that feels polished, private, and enjoyable.

And that’s the purpose: with only a brief video and a foolish thought, anybody can create a comic book that appears prefer it belongs on the web’s entrance web page.
