HunyuanVideo is an open-source text-to-video model from Tencent, released in late 2024, praised for strong motion coherence and fast generation. It’s one of two models powering AI video on AllMediaTools — here’s what it does well, where it falls short, and how to get the best results.
What Is HunyuanVideo?
A ~13 billion parameter diffusion transformer trained for text-to-video generation. Tencent released the weights openly, which is why it’s available through free tools like AllMediaTools rather than locked behind a single paid platform.
| Spec | Value |
|---|---|
| Parameters | ~13 billion |
| Generation speed (AllMediaTools) | ~1.5 minutes/clip |
| Resolution served | 480p (for speed/capacity) |
| Clip length | A few seconds |
What It Generates Well — and Where It Struggles
✓ Strong at
- Fast motion and action (running, water, spinning objects)
- Camera movement (pans, zooms, tracking)
- Stylized/abstract content
- Fast iteration — generate 5–10 variations quickly
✗ Current limitations
- Faces and detailed hand movement remain imperfect
- Multi-step actions often only partially execute
- Short clips need stitching for longer sequences
How to Generate Video with HunyuanVideo
- Open AllMediaTools AI Video Generator.
- Select HunyuanVideo as the model.
- Enter your prompt and choose orientation.
- Click Generate (~1.5 minutes) and download.
Prompt Formula
[Subject/scene] + [specific motion] + [visual style] + [camera behavior] + [lighting/mood]
Example:
A cheetah running across golden savanna grass, dust kicking up behind it,
slow-motion, cinematic wildlife photography, warm afternoon light,
camera tracking alongsideAvoid: precise hand-object interactions, detailed facial expressions or dialogue, and long multi-step narratives. Keep it to one clear motion or scene.
HunyuanVideo vs Wan 2.1
| Factor | HunyuanVideo | Wan 2.1 (14B) |
|---|---|---|
| Generation time | ~1.5 min | ~3.5 min |
| Motion smoothness | Very good | Excellent |
| Detail/texture | Good | Very good |
| Best for | Fast iteration | Final, highest-quality render |
Practical workflow: draft with HunyuanVideo, then regenerate your best prompt in Wan 2.1 for the final version. See the Wan 2.1 practical guide and our full AI video generator comparison.
After Generating
Output is MP4 at 480p — fine for TikTok/Shorts, soft on larger displays. Run it through AllMediaTools Video Compressor before upload, and combine multiple clips in CapCut or DaVinci Resolve for longer sequences.
Frequently Asked Questions
Is HunyuanVideo better than Wan 2.1?
Neither is strictly better — HunyuanVideo is roughly twice as fast, while Wan 2.1 14B produces slightly higher detail. Many workflows use HunyuanVideo for drafts and Wan 2.1 for the final render.
Is HunyuanVideo free to use?
The model is open-source. Via AllMediaTools, generation is free for basic use with no local hardware required.
Who developed HunyuanVideo?
Tencent developed and released HunyuanVideo as an open-source model in late 2024.
