HunyuanVideo 1.5 - Everything you Need to Know about Tencent's best Video Model

HunyuanVideo-1.5 is a professional-grade text-to-video generator that produces highly realistic videos with smooth, coherent motion.

It's particularly strong at creating videos that look natural and polished — the kind of quality you'd expect from a much larger, more resource-intensive model.

What is HunyuanVideo 1.5?

HunyuanVideo-1.5 is Tencent's video generation model that delivers top-tier visual quality despite being remarkably lightweight.

It can generate videos at up to 1080p resolution with excellent motion coherence — meaning movements look smooth and realistic rather than jittery or artificial.

HunyuanVideo 1.5 Key features:

  • Generates high-quality videos with professional-grade visual quality
  • Produces smooth, natural-looking motion and realistic physics
  • Supports both text-to-video and image-to-video workflows
  • Creates videos at up to 1080p resolution with enhanced sharpness
  • Excels at aesthetic quality and human preference alignment

In other words, HunyuanVideo-1.5 is built for quality, while being remarkably lightweight. Use it when you need to generate videos with natural motion, are OK with generating a video without sound, and aren’t looking for the best quality available — if you need one of the best ai video generation tools, check out Sora 2 or Veo 3.1, though these consume more credits.

💡 What Makes It Special?

HunyuanVideo 1.5 generates professional-quality videos with only 8.3 billion parameters, which is remarkably small for a video model. The Tencent team created a new type of attention mechanism called SSTA, which makes the model nearly twice as efficient as competitors without compromising quality.

This is especially important for those who install and run AI models on local machines because it enables people with relatively inexpensive hardware to generate videos. It is also valuable for online use cases, such as Overchat AI, as it reduces the cost per generation, enabling you to create more videos. 

When Should You Choose HunyuanVideo 1.5?

In short, HunyuanVideo 1.5 is a text-to-video generation model. This means that you would use it to create videos from text prompts, not to animate images.

HunyuanVideo 1.5 offers a good balance of cost and performance, costing only 200 credits in Overchat AI. That being said, it’s not particularly fast — if you want to try many ideas quickly, you might want to check out Sana 2 instead. On the other hand, if you want the best possible quality, Sora 2 is the way to go, even though it consumes 800 credits per generation.

That being said, choose HunyuanVideo 1.5 when you need:

  • Polished videos
  • Complex motion and physics

What types of videos can you create?

Use HunyuanVideo 1.5 to create videos in these genres:

- Marketing videos

- Concept art

- Viral videos

- Stock footage

Cost and Pricing

HunyuanVideo 1.5 costs 200 tokens per generation on Overchat AI. This makes it one of the most cost efficient AI video generation models that we support, allowing you to crete more.

Where to Access HunyuanVideo 1.5? 

Normally, developers would run HunyuanVideo-1.5 locally on their own machines, using interfaces like ComfyUI to communicate with the model. This workflow has a rather difficult learning curve — a much easier alternative is to access HunyuanVideo 1.5 online in Overchat AI's video generator. From here, you can use it online without installing or downloading anything.

That being said, if you’re interested in running this model locally, you can install it from the project’s official github — use this link, but be warned that if you’re not a developer, you might find this a bit complicated.

Bottom Line

HunyuanVideo-1.5 is a professional-grade video generation model from Tencent.

HunyuanVideo-1.5 promises exceptional video quality, particularly smooth motion, at a fraction of the cost of the best AI video models, such as Sora 2 and Veo 3.1. It is a text-to-video generation model, meaning you would use it to create videos from text prompts rather than to animate images. This makes it versatile for a wide range of creative projects. Although it may be slower than ultra-fast models, the polished, professional results are well worth the wait.

At Overchat AI, we're constantly adding new models, bringing you the latest AI tools, video, and image generators. For example, we’ve recently added Gemini 3 — the smarter AI from Google, and Nano Banana Pro (also called Nano Banana 2) — their most advanced image generator. More exciting updates are on the way, so stay tuned for even more exciting updates in the near future.
