Experiments
The experimental design includes evaluating multiple comedy video datasets. The primary dataset is a collection of comedy videos from YouTube, featuring clips of various styles and languages. The experiments use viewer ratings and diversity tests as evaluation metrics. Baseline methods include traditional video generation techniques and existing comedy generation systems. Ablation studies assess the impact of the LLM critic and agent population on system performance.
Results
Experimental results show that the COMIC system excels in both quality and diversity. Specifically, the system achieved an average viewer rating of 4.5 stars on YouTube, closely matching the 5-star ratings of professional productions. In diversity tests, COMIC-generated videos covered over 80 different humor styles, significantly surpassing the 50 styles achieved by traditional methods. Additionally, ablation studies revealed that removing the LLM critic module resulted in a 20% drop in viewer ratings for generated videos, highlighting the module's critical role.

Additionally, it can be applied to online content platforms, helping creators enhance content appeal and viewer engagement.
Limitations & Outlook
Despite the COMIC system's excellence in short comedic video generation, it has limitations. Firstly, the system performs poorly with non-English videos as its LLM critics are primarily trained on English corpora. Secondly, the system's performance declines in generating long-form comedy videos, indicating potential limitations in its agent structure and optimization mechanism.

Plain Language Accessible to non-experts
Imagine you're in a kitchen preparing a grand feast. You have a team of chefs, each with their own specialty: one excels at chopping, another at seasoning, and another at cooking. You provide them with some basic ingredients and a rough recipe, then let them get to work. Each chef adjusts the recipe based on their expertise, trying to create the most delicious dish.
During this process, you also invite a food critic to taste each dish and provide feedback. The critic's opinions help the chefs refine their dishes, ultimately creating a perfect dinner. This is similar to how the COMIC system works: each agent is like a chef, generating ideas based on their role, while the LLM critic acts like the food critic, evaluating humor based on viewer preferences.
Through this approach, the COMIC system can generate high-quality and diverse comedic videos, much like a well-prepared dinner that satisfies the audience.

Hey there! Imagine you and your friends are playing a game where everyone has to come up with a funny story. Each person has a role, like one is the director, another is the writer, and someone else is the actor. You all brainstorm and come up with all sorts of funny scenes.
Then, you invite a super funny teacher who tells you which stories are the funniest and which ones need some work. The teacher is like the LLM critic in the COMIC system, evaluating your stories based on what viewers like.
By doing this, you all end up creating a super funny short video that makes everyone laugh! That's how the COMIC system works, helping AI create funny comedy videos, just like you guys creating funny stories together.
So next time you see a funny video, it might just be created with the help of the COMIC system!
