Hunyuan Video is an AI text-to-video generator that excels at turning text prompts into cinematic-quality videos.
The model can generate videos at resolutions up to 1024×576 pixels and up to 16 seconds in length.
It supports different levels of GPU, with even lower VRAM (24GB minimum) still affecting video quality and generation speed.
Hunyuan Video is a novel open-source video foundation model developed by Tencent, designed for high-quality video generation from text descriptions. It integrates data curation, image-video joint model training, and an efficient infrastructure to facilitate large-scale model training and inference. Hunyuan Video aims to bridge the gap between closed-source and open-source video foundation models, empowering the community to experiment with AI-driven video creation.

Hunyuan Video distinguishes itself as a novel open-source video foundation model, a deliberate effort to democratize access to advanced AI video generation technology. Tencent’s release of the model’s code and weights aims to bridge the gap between proprietary, closed-source alternatives and the open-source community.
Only Text-to-Video
Hunyuan Video is presented as a text-to-video (T2V) model. The image-to-video model’s release has been delayed, with a possible release expected later.
Hardware Requirements
Considering these points, the hardware requirements can be considered relatively high for individual users but more accessible compared to some competing AI video generation models.
Basic Requirements: • VRAM: 24GB minimum, 45GB recommended, 80GB optimal • GPU: NVIDIA with CUDA support • RAM: 32GB • Storage: 100GB free space
Unified Generation Framework • Leverages advanced Transformer with Full Attention • Unique “Dual-to-Single stream” design • Seamlessly fuses video and text processing
Enhanced Language Understanding • Powered by Multimodal LLM (MLLM) • Decoder-Only structure excels at detail comprehension • Superior image-text alignment vs traditional CLIP/T5 models
Efficient Video Processing • Advanced 3D VAE with CausalConv3D • Optimized latent space compression • Maintains high quality at original resolution/framerate
Smart Prompt System • Built-in prompt optimization engine • Two modes: Normal (basic) and Master (detailed) • Automatically reformats user inputs for optimal results
Comparisons
VBench is a robust and comprehensive benchmark suite designed to evaluate video generative models. It breaks down “video generation quality” into hierarchical, disentangled, and specific dimensions, each equipped with tailored prompts and evaluation methods. The main evaluation metrics include:
Large Motion Generation
Human Artifacts
Pixel-Level Stability
ID Consistency
Physical Plausibility
Smoothness
Comprehensive Image Quality
Scene Generation Quality
Stylization Ability
Single Object Accuracy
Multiple Object Accuracy
Spatial Position Accuracy
Camera Control
Action Instruction Following
Currently there are no authoritative V-Bench evaluations for Hunyuan, only experiments conducted by Hunyuan themselves on GitHub. Here are their testing methods:
To evaluate Hunyuan Video’s performance, they selected five strong baselines from closed-source video generation models. They used 1,533 text prompts, generating an equal number of video samples with HunyuanVideo in a single run. To ensure fairness, they only ran inference once, avoiding cherry-picking results. When comparing with baseline methods, they used default settings for all selected models to maintain consistent video resolution. Videos were evaluated on three criteria: Text Alignment, Motion Quality, and Visual Quality. Over 60 professional evaluators conducted the assessment. Hunyuan Video showed the best overall performance, particularly in motion quality. Note that this evaluation used Hunyuan Video’s high-quality version, which differs from the current fast version release.
