This workflow is intended to allow video generation with the incredible Hunyuan Model with 12gb vram (tested on 4070). Workflow isn't fancy, as I hate those workflows. I perfer simple workflows you can easily adapt to your needs.

With this workflow, you can generate your videos at a lower resolution (720x416 in my tests), then upscale to 1080p and generate new frames to result in a higher resolution, longer video. This also includes the ability to use wildcards and combination prompts.

Required models

Hunyuan BF16 or Hunyuan FP8 or Hunyuan Fast

Hunyuan VAE

Foolhardy Remacri 4x (or your favorite upscaler)

Workflow include a optional node to hook to a local instance of Ollama if you wanted to generate prompts with LLMs. (Disabled by default)
