ViMax: Agentic Video Generation
🚨 Current Video Generation Limitations:
- ❌ Limited to Short Clips - Most AI tools generate only seconds of footage.
- ❌ Consistency Chaos - Characters and scenes change unpredictably across frames.
- ❌ Visual-Only Focus - Missing scripts, audio, narrative structure, and storytelling depth.
💡 ViMax Solution:
🎬 Director, Screenwriter, Producer, and Video Generator All-in-One! We're exploring a future where AI becomes a complete creative powerhouse. 💡 Simply input your concept. ViMax autonomously handles the rest. It orchestrates scriptwriting, storyboarding, character creation, and final video generation—all end-to-end. 🚀

✨ Key Features
ViMax is an agentic video creation framework that connects narrative planning, visual consistency, image generation, video generation, and final assembly in one extensible workflow.
- Idea2Video — turn a short concept into structured stories, characters, scripts, storyboards, shots, and a finished video.
- Script2Video — convert an explicit screenplay into controllable multi-scene, multi-shot video while preserving its creative intent.
- Novel2Video — adapt long-form fiction into episodic visual narratives with narrative compression, character tracking, and scene planning.
- AutoCameo — place a person or pet from a reference photo into generated stories while maintaining a consistent appearance.
- Agent Loop and TUI — discuss ideas, revise plans, resume sessions, review text artifacts, and control rendering from one interactive workspace.
- Web UI — manage named projects, work with the ViMax Agent, upload source files, inspect artifacts and storyboard progress, preview renders, and configure providers from the browser.
- Consistent production pipeline — coordinate references, first frames, camera continuity, and final assembly end to end.
- Parallelized generation — generate compatible shots and media assets concurrently to accelerate multi-shot video production.

🖥️ ViMax Web UI
The Web UI brings agent conversation, project artifacts, storyboard previews, and render progress into one visual workspace.
🎯 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.

🚀Quick Start
🖥️ Environment
OS: Linux, Windows
📥 Clone and Install
We use uv to manage the environment. For uv installation, please refer to the https://docs.astral.sh/uv/getting-started/installation/.
git clone https://github.com/HKUDS/ViMax.git
cd ViMax
uv syncAgent TUI
ViMax also provides a minimal TUI for interactive agent-based video creation. Create a private local configuration from the tracked example first:
cp configs/agent.example.yaml configs/agent.local.yamlThen configure the model and API key information in configs/agent.local.yaml, including the LLM, image generator, and video generator, as shown below.
llm:
model_provider: openai
model: <YOUR_LLM_MODEL>
base_url: <YOUR_LLM_BASE_URL>
api_key: <YOUR_API_KEY>
image:
model: <YOUR_IMAGE_MODEL>
base_url: <YOUR_IMAGE_BASE_URL>
api_key: <YOUR_API_KEY>
video:
model: <YOUR_VIDEO_MODEL>
base_url: <YOUR_VIDEO_BASE_URL>
api_key: <YOUR_API_KEY>Then, start the TUI from the ViMax root directory:
vimax tuiStart a new session or resume an existing one:
vimax tui new
vimax tui resume
vimax tui resume <session_id>You can also keep configs/agent.local.yaml empty and provide the same values through environment variables, such as VIMAX_LLM_API_KEY, VIMAX_IMAGE_API_KEY, and VIMAX_VIDEO_API_KEY.
Web UI
The Web UI uses the same ViMax agent runtime, sessions, tools, and private configs/agent.local.yaml configuration as the TUI. Node.js 18 or newer is required.
From the ViMax repository root, install the frontend dependencies once and start the local server:
cd web
npm install
npm run devOpen http://127.0.0.1:4173 in your browser. The Web UI supports named projects, agent conversations, slash commands, artifact and render inspection, storyboard previews, file uploads, and provider settings.
The server binds to 127.0.0.1 by default. When ViMax runs on a remote machine, forward the port from your local computer:
ssh -N -L 4173:127.0.0.1:4173 <user>@<server>Use VIMAX_WEB_PORT when another local port is required:
VIMAX_WEB_PORT=4174 npm run devUsage
Image Selection
ViMax generates 2 keyframe candidates in parallel and selects one using your vision-capable chat model. This can improve visual quality and consistency, at a higher API cost. Set in your YAML config:
image_selection:
num_candidates: 2 # Set to 1 to disable selection.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/idea2videoThen, provide a simple yet thoughtful idea and the corresponding creative requirements in main_idea2video.py.
idea = \
"""

"""
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.

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!
