🎯 End-to-End Video Creation Engine
The Challenges:
🌅 Reference Images: Time-consuming acquisition, organization, and alignment of reference frames that accurately capture characters, objects, positions, and environments.
🫠 Consistency Check: Sometimes, the image generator may generate unusable images even if it is given the correct characters, position, environment reference image and prompts.
📄 Scripts Generation: Professional and high-quality videos need to have rich information density and structured design.
📝 Storyboard Design: Converting stories into visual narratives requires expertise in cinematography, scene composition, and visual storytelling that most creators lack.
🎬 Shot Design: Creating coherent camera sequences with proper angles, transitions, and pacing while maintaining narrative flow across complex scenes.
🎨 Development Delays: Ensuring character appearances, environments, and artistic style remain consistent across hundreds of shots in long-form content.
⏱️ Production Efficiency: Traditional video creation involves multiple specialists and lengthy workflows, creating barriers for independent creators and rapid prototyping.
🎥 Scaling AI Generated Video: AI-generated videos are usually only a few seconds long, high-quality long videos at the minute or even hour level require complex cross-scene continuity and multi-storyboards design and processing capabilities.
ViMAX: eliminates these production bottlenecks by automating the entire video creation pipeline from narrative input to final video output.

🏗️ Architecture
📊 System Overview
ViMax is a multi-agent video framework that enables automated multi-shot video generation while ensuring character and scene consistency. Our system seamlessly translates your ideas into corresponding videos, allowing you to focus on storytelling rather than technical implementation.
🎯 Technical Capabilities:
🧬 Intelligent Long Script Generation
RAG-based long script design engine that intelligently analyzes lengthy, novel-like stories and automatically segments them into a multi-scene script format. The process meticulously ensures that all key plot developments and character dialogues are accurately retained within the new structure.
🪄 Expressive Storyboard Design
Shot-level storyboard design system that create expressive storyboards through cinematography language based on user requirements and target audiences, which establishs the narrative rhythm for subsequent video generation.
🔮 Multi-camera Filming Simulation
Simulates multi-camera filming to deliver an immersive viewing experience while maintaining consistent character positioning and backgrounds within the same scene.
🧸 Intelligent Reference Images Selection
Intelligently select the reference image required for the first frame of the current video, including the storyboards that occurred in the previous timeline, to ensure the accuracy of multiple characters and environmental elements as the video becomes longer.
⚙️ Automated Images Generation
Based on the selected reference image and the visual logical order on the previous timeline, the prompt of the image generator is automatically generated to reasonably arrange the spatial interaction position between the character and the environment.
✅ Automated Image Generation Consistency Check
Generate multiple images in parallel and select the best consistent image as the first frame through MLLM/VLM to imitate the workflow of human creators.
⚡ High-efficiency Parallel Shot Generation
Parallel processing for sequential shots captured from the same camera enables highly efficient video production.

🎯 Usage
main_idea2video.py is used to convert your ideas into videos. You need to configure the model and API key information in the configs/idea2video.yaml file, including three parts—the chat model, the image generator, and the video generator, as shown below
chat_model:
init_args:
model: google/gemini-2.5-flash-lite-preview-09-2025
model_provider: openai
api_key: <YOUR_API_KEY>
base_url: https://openrouter.ai/api/v1
image_generator:
class_path: tools.ImageGeneratorNanobananaGoogleAPI
init_args:
api_key: <YOUR_API_KEY>
video_generator:
class_path: tools.VideoGeneratorVeoGoogleAPI
init_args:
api_key: <YOUR_API_KEY>
working_dir: .working_dir/idea2video
Then, provide a simple yet thoughtful idea and the corresponding creative requirements in main_idea2video.py.
idea = \
"""
If a cat and a dog are best friends, what would happen when they meet a new cat?
"""
user_requirement = \
"""
For children, do not exceed 3 scenes.
"""
style = "Cartoon"
main_script2video.py generates a video based on a specific script. You similarly need to set up the API configuration in configs/script2video.yaml file. Then, provide a scene script and the corresponding creative requirements in main_script2video.py, as shown below.
script = \
"""
EXT. SCHOOL GYM - DAY
A group of students are practicing basketball in the gym. The gym is large and open, with a basketball hoop at one end and a large crowd of spectators at the other end. John (18, male, tall, athletic) is the star player, and he is practicing his dribble and shot. Jane (17, female, short, athletic) is the assistant coach, and she is helping John with his practice. The other students are watching the practice and cheering for John.
John: (dribbling the ball) I'm going to score a basket!
Jane: (smiling) Good job, John!
John: (shooting the ball) Yes!
