Tencent's open-weights video generation model: one of the first open releases to rival closed leaders on motion realism and cinematic camera work, with 13B parameters you can run yourself.

Product preview

Overview

When Tencent released HunyuanVideo's weights in late 2024, it reset expectations for what open video models could do: reviewers immediately ranked it alongside closed leaders on motion coherence and its signature cinematic sensibility — dolly moves, depth-of-field, dramatic lighting — which most open models of the time could not hold together.

It is a 13B model, which means serious VRAM for local use, but the community answered with quantizations, distilled variants and ComfyUI pipelines that bring it to prosumer rigs. The companion Hunyuan family (image, 3D, speech) shares the research backbone. Compared with Wan it is heavier and slower to iterate, but its camera realism remains a benchmark — for cinematic b-roll owned end to end, HunyuanVideo earns its GPU time.
