879 "## How to use - Hunyuan Video Low-VRAM v1.1.2\n\n**What it does:** text to video with Fast Hunyuan Video (GGUF), RifleX, a tiled decode and a 4x anime upscale. Made for very small cards (4 GB). It works but it is slow; Wan 2.1 / 2.2 GGUF is often the better pick on tiny GPUs.\n\nThis file is text to video only: there is no image input in this graph.\n\n**Inputs**\n1. **Positive prompt** (top CLIP Text Encode in Prompts): describe the scene, action and camera.\n2. **Negative prompt** (lower CLIP Text Encode): empty by default.\n3. **LoRAs** (Lora Loader Stack, rgthree): all four slots are \"None\". Pick Hunyuan Video LoRAs here if you want them.\n\n**Important settings**\n- **Empty Video Latent For Hunyuan**: size 768x432 (16:9), 25 frames, batch 1.\n- **Hunyuan Video Sampler Save**: 20 steps, cfg 6, euler / beta, denoise 0.9, seed randomizes each run.\n- **FluxGuidance**: 6 on the positive, 2 on the negative.\n- **ModelSamplingSD3**: shift 5.\n- **RifleX RoPE**: k 4 (helps longer clips not repeat).\n- **HyVideo Decode**: tiling on (tile size widgets 32 and 64, auto tile size off). Keep it on for low VRAM.\n- **Upscale**: 4x-AnimeSharp, then Image Scale (lanczos, center crop) to 1095 x 1930. That target is portrait; for the default 16:9 latent set width/height to a 16:9 size or the center crop cuts the sides.\n\n**Outputs**\n- **Video Combine**: the upscaled clip as MP4 (10 fps, pingpong on).\n- **Save Animated WEBP**: the raw decode before upscaling (6 fps).\n\n**Tips**\n- Out of VRAM: fewer frames, a smaller latent size, or bypass the upscale nodes.\n- GGUF errors are usually fixed by updating the gguf node pack.\n- Faster attention: start ComfyUI with --use-sage-attention (less VRAM). --use-ck-attention changes the image for the same seed.\n\n**Tested on:** RTX 3050 Laptop 4 GB (slow)."
