What is Hunyuan Video
Hunyuan Video is a state-of-the-art, high-fidelity AI video model developed by Tencent. It is well-known in the open-source community as being among the largest video foundation models available, powered by a massive 13-billion-parameter diffusion transformer model. This robust technology allows it to process both image and text inputs in a unified system, giving it a powerful multimodal capability. The model's major strengths are its capacity to generate videos of cinematic quality, high visual consistency, and fluid motion. The model is good at understanding intricate text descriptions and translating them into engaging, visually appealing scenes with strong text-to-video alignment.
Key features of Hunyuan Video AI
- 1
- High-fidelity text-to-video generation: Hunyuan Video possesses the ability to transform complex text descriptions into high-definition, film-style video clips. It's known for strong text-to-video alignment, motion diversity, and stable results even from simple prompts. 2
- Advanced image-to-video capabilities: The model is capable of transforming a static image into a dynamic, moving video. This Hunyuan image-to-video feature maintains the fine details and textures of the original image while generating fluid, lifelike motion. 3
- Hunyuan avatar for audio-driven animation: A specialized version, HunyuanVideo-Avatar, that facilitates the creation of high-fidelity, audio-driven human animations. It is capable of generating dynamic, emotion-controllable videos of one or more characters from a reference image and an audio clip, with natural lip-sync and facial expressions. 4
- Exceptional scene and character consistency: The model performs immensely well in maintaining consistent quality, lighting, and character integrity throughout a video clip, reducing the typical issues of frame drops or visual breakdowns faced by other models. It can also be combined with LoRA (Low-Rank Adaptation) for character consistency across multiple scenes. 5
- Multimodal & versatile architecture: The core of Hunyuan Video is a robust 13-billion-parameter diffusion transformer that can handle both image and text inputs. This multimodal approach allows one system to generate still images and videos equally, making it an adaptable tool for any type of creative work.
How to use Hunyuan AI video generator
Getting started with Hunyuan AI is straightforward, whether you want to create videos from text or animate avatars. The two primary methods for generating content are through text prompts or by using an avatar generator with an image and audio.
Method 1: Using Hunyuan AI's text to video generator
- STEP 1
- Access the platform and enter your prompt
Navigate to the Hunyuan Video platform at hunyuanvideo.org and click "Try it Free" to access the generation interface.
From the creation interface, click on "text-to-video," then in the text input field, describe the video you want to create in natural language. Be specific about scenes, actions, and visual style (e.g., "A lonely robot walking through a dusty desert at sunset, casting long shadows on the cracked earth. Shot in a cinematic wide-angle style, 3D animation, photorealistic.").
- STEP 2
- Customize settings
Below the prompt field, adjust the video duration using the slider (limited to up to 8.5 seconds). Optionally, enable "Improve Texture (multi-scale)" for better quality, though it's slower. You can also adjust advanced settings such as negative prompt, seed value, and resolution (height and width).
- STEP 3
- Generate and download
Click "Generate Text-to-Video" to start the process, which may take a few minutes or more depending on the length and server load. Once complete, preview the MP4 output, then click the "Download" icon to save it to your device or the "Share" icon for easy sharing.
Method 2: Using Hunyuan's avatar video creator
- STEP 1
- Upload your image and audio
Visit the Hunyuan Avatar platform and sign up for free to get started. Drag and drop a high-resolution image showing clear facial features from your computer, or paste it from the clipboard (Ctrl/Cmd+V) or provide a URL. Similarly, upload an audio file by dragging and dropping, pasting, or providing a URL, ensuring it's clear and matches the desired video duration. If you don't have an audio, click on the "mic" icon to record your audio on the platform. Make sure your audio is within 8 seconds.
- STEP 2
- Refine generation parameters
Customize the input with additional settings: optionally add a text prompt (e.g., "A professional speaking confidently") to describe the scene, set the number of frames, adjust the number of inference steps, and enable turbo mode for faster processing. Ensure the image is well-lit with the subject facing the camera for optimal results.
- STEP 3
- Generate and download
Click the "Run" button to process the avatar animation, which takes approximately 8 minutes. Once complete, review the output video (MP4 format) for natural lip-sync and movements. Download the file using the provided URL or use the queue API with a webhook for long-running requests, noting the cost of $1.40 for a 5-second video.
- High-quality output: Hunyuan AI, particularly its video model, is known for generating high-resolution, cinematic-quality videos. It produces smooth, natural-looking motion and maintains consistent quality with minimal glitches or frame drops.
- Strong prompt understanding: The model excels at interpreting natural language prompts. It has a high semantic understanding, allowing it to produce impressive and contextually accurate videos from simple text descriptions.
- Excellent visual consistency: Hunyuan maintains consistent character appearance, lighting, and scene details throughout a video clip, which is a major challenge for many AI models. It also performs well in complex, multi-person scenes.
- Open-source and accessible: Tencent has made Hunyuan AI's core code and pre-trained weights public and free for commercial use. This encourages community-driven innovation and allows developers to integrate and fine-tune the model for various applications without high licensing costs.
- High computing power requirement: To run locally and achieve optimal performance, Hunyuan requires significant hardware resources, specifically a high-end GPU with a large amount of VRAM (45GB minimum, 80GB recommended). This can be a major barrier for individual creators.
- Limited creative control: While its prompt understanding is strong, Hunyuan can be less flexible than some competitors when it comes to advanced, granular control. It may lack specific options for features like frame-by-frame editing, direct camera path control, or audio generation.
- Challenges with complex actions: The model can sometimes struggle with certain content, such as fast-paced action sequences or specific, detailed facial expressions. It may produce stiff or unnatural motion in complex scenarios.
While Hunyuan Video delivers impressive cinematic outputs, its steep hardware requirements and limited editing flexibility make it less practical for everyday creators. Many users find it challenging to experiment or refine videos without powerful GPUs or advanced technical knowledge. This creates the need for a more accessible, browser-based solution. That is where CapCut Web comes in, offering AI-powered video creation and editing tools without the heavy system demands.
