Unlock Stunning Architecture Animations: A Low-VRAM Workflow Guide
1. Workflow Overview

This architecture animation workflow is optimized for low-VRAM devices (6GB+), generating up to 60s videos. Key features:
Input: Static building image (e.g.,
work-04.jpg
) β Output: Camera motion animation (push-in, orbit, etc.)Uses tiled decoding and model quantization (
FramePack
BF16)Exports 30FPS MP4 (H.264, 512x512 default)
2. Core Models
Model Name | Function |
---|---|
| Main video generation model (Hunyuan architecture) |
| Video VAE decoder (BF16 precision) |
| Dual-CLIP text encoder (multimodal prompts) |
3. Key Nodes
Node Name | Function | Installation |
---|---|---|
| Controls video generation (supports | Requires |
| Tile-based decoding (128x128 tiles) | Built-in |
| Video rendering (needs | Via ComfyUI Manager |
| Smart resizing ( | Install |
4. Workflow Groups

5. Inputs & Outputs
Inputs:
Image: 608x640 JPG/PNG (auto-resized to 512x512)
Motion prompt: Verb-centric phrases (e.g., "Drone flyover of buildings")
Seed: Fixed at
47
for reproducibility
Output:
512x512 MP4 (YUV420P with metadata)
6. Notes
VRAM Optimization:
Use
tile_size=128
for 6GB VRAM (60s video max)Do NOT modify
temporal_overlap=8
to avoid crashes
Prompt Tips:
Use action-focused short phrases (e.g., "Pan across the skyline")
Negative prompts are pre-configured
Troubleshooting:
Model Download: Manually place

Choppy Video: Reduce

to 24 or shortentotal_second_length
