Modified workflow from the AI ​​Verse model: Click here to see the AI ​​Verse version.

I tested this workflow on an RTX 3060 video card with 12GB and 34GB of RAM, at 480x848 and 576x1024 resolutions.

I modified the model loader and started using the Load Diffusion Model. I installed the Power Lora Loader (rgthree). For export, I started using Video Combine VHS.

It works, but it is recommended not to have other activities in the background, as it required all the system resources.

Base model: Hunyuan Video FastVideo 720 Fp8 e4m3fn - Place in: ComfyUI_windows_portable\ComfyUI\models\diffusion_models

Dual Clip Loader: Clip_I.safetensors and llava_lhama3_fp8_scaled.safetensors - Place in: ComfyUI_windows_portable\ComfyUI\models\text_encoders

Vae: hunyuan_video_vae_bf16.safetensors - Place in: ComfyUI_windows_portable\ComfyUI\models\vae

You can leave everything else as default, or follow the notes. For low VRAM, try decreasing the tile_size and overlap values.
