Whether you're animating a static image or bringing creative prompts to life, Hunyuan Custom ensures that the generated videos are both lifelike and consistent, preserving the unique features and identity of the subject.
The model supports flexible input options, including uploading an image to serve as the base for identity preservation. Users can input a detailed text prompt (up to 500 characters) to guide the video’s content, while a negative prompt option allows for the exclusion of unwanted elements such as blurring, distortion, or low-quality visuals. Hunyuan Custom offers two resolutions—512p for standard projects and 720p for high-definition needs—alongside adjustable aspect ratios (16:9 landscape or 9:16 portrait) to suit various platforms and creative requirements.
Hunyuan Custom stands out with its extensive customization settings. Users can specify the number of inference steps (10-30) for optimal quality, select the number of frames (81-129) for video duration, and set the frame rate (16-30 FPS) for smooth playback. The classifier-free guidance (CFG) scale (1.5-13) gives advanced users fine control over output fidelity and creativity. Automatic prompt expansion further enhances prompt interpretation, ensuring rich and nuanced video results.
Security and content integrity are prioritized with an integrated safety checker, and reproducibility is supported through optional seed settings. The model’s fusion technology ensures that the subject’s identity and features remain consistent across all frames, making it especially valuable for projects where visual continuity is paramount. Videos are generated quickly, often within 90-180 seconds, streamlining creative workflows.
Ideal use cases include content creation for marketing campaigns, social media storytelling, personalized video messages, entertainment, educational content, and brand animations. Hunyuan Custom allows you to transform static images into dynamic, high-quality videos that captivate audiences and elevate your creative output. With pay-as-you-go credit-based pricing, users have the flexibility to scale projects according to their needs, focusing on value and results rather than upfront costs.

Frequently Asked Questions
Hunyuan Custom uses advanced fusion modules to preserve the unique features and identity of the input image across all video frames, ensuring visual integrity and continuity throughout the generated video.
You can upload any image file or provide an image URL as the base for video generation. The model also requires a detailed text prompt to guide the video content.
Yes, you can adjust the number of frames, inference steps, frame rate, aspect ratio, and resolution, allowing precise control over video length and output quality.
Pricing varies by model and is based on a pay-as-you-go credit system, enabling flexible and scalable use according to your project needs.
Yes, the integrated safety checker automatically reviews generated content to ensure compliance and prevent the creation of unsafe or inappropriate videos.
Hunyuan Custom uses a pay-per-generation credit system where 512p videos consume baseline credits, while 720p output costs 50% more due to increased resolution. Compared to
Kling Video v3 Standard Image to Video, Hunyuan Custom typically uses similar credits for standard resolution but offers better facial consistency.
LTX 2.3 Image to Video Fast may cost slightly less per generation but produces shorter clips. For budget-conscious projects requiring multiple iterations, start with 512p in Hunyuan Custom to test prompts, then upgrade to 720p only for final approved videos. JAI Portal's credit model means you only pay for successful generations—no monthly subscription fees or unused capacity.
Yes, all videos generated using paid credits on JAI Portal come with full commercial-use rights. This includes client deliverables, advertising campaigns, social media content, YouTube monetization, product demos, and corporate presentations. You own the output and can license it to clients or use it in revenue-generating projects without additional fees. This applies whether you generate at 512p or 720p resolution. The commercial license covers the final video file but not the underlying model architecture. For high-volume agency work or white-label services, the pay-as-you-go credit system scales efficiently—purchase credits in bulk during campaign peaks and use them across any JAI Portal model, including Hunyuan Custom, without expiration pressure.
Hunyuan Custom generates MP4 video files with H.264 encoding, optimized for broad platform compatibility including YouTube, Instagram, TikTok, LinkedIn, and website embedding. At 512p resolution, output dimensions are typically 512×288 (16:9) or 288×512 (9:16). The 720p option delivers 1280×720 or 720×1280 respectively. Frame rates range from 16-30 FPS based on your settings, with 25 FPS as the default for smooth, natural motion. Video duration depends on frame count (81-129 frames) and FPS—at default settings (129 frames, 25 FPS), you get approximately 5-second clips. All videos include audio silence by default; add music or voiceover in post-production. Files are delivered via direct download link immediately after generation completes.
Hunyuan Custom's identity-consistency technology works across all ethnicities, age groups, skin tones, and facial structures. The model has been trained on diverse datasets to accurately preserve features including different eye shapes, nose structures, hair textures, and facial proportions. Whether animating portraits of children, elderly subjects, or individuals with distinctive features like glasses or facial hair, the fusion modules maintain visual integrity across all frames. For best results with any demographic, ensure your input image has clear facial visibility and even lighting. The model treats all subjects equally—there's no quality degradation based on ethnicity or age. If you encounter inconsistency, it's typically due to input image quality (blur, shadows, extreme angles) rather than the subject's features themselves.
JAI Portal supports API access for developers and agencies who need to integrate Hunyuan Custom into automated pipelines or batch-processing workflows. Through the API, you can submit multiple generation requests programmatically, monitor job status, and retrieve completed videos without manual intervention. This is ideal for agencies processing client photo collections, e-commerce platforms creating product videos at scale, or SaaS tools embedding video generation features. API usage consumes the same pay-as-you-go credits as manual generations, with no additional API fees. Rate limits and concurrent job slots scale with your credit balance. For teams needing batch capabilities without custom development, consider using JAI Portal's web interface to queue multiple generations sequentially—each completes in 90-180 seconds, allowing efficient processing of small to medium batches.
⚖️ How Hunyuan Custom Compares
