ComfyUI for Local AI Video: Installation Paths, Native Workflows & Hardware Reality
A practical documentation-first guide to using ComfyUI as a local workflow engine for AI video. The key distinction is simple: a computer may run ComfyUI while still lacking the memory or backend support required by a particular video model.
Technical research notice
This guide is based on official ComfyUI documentation, official model repositories and official workflow templates. Unless explicitly marked Hands-on Tested, VideoToolMap has not independently tested the exact hardware/model combinations described here.
ComfyUI itself does not define one universal VRAM requirement for AI video. Actual requirements depend on the model, precision, offloading, resolution, frame count and workflow.
Quick verdict
Best starting path
Use an official ComfyUI installation path, then choose the video model before planning VRAM.
Best workflow rule
Prefer native/official templates before adding third-party custom nodes.
Biggest hardware mistake
Buying a GPU because it can run ComfyUI instead of checking the exact video model/workflow.
Best evidence rule
Treat official requirements as documentation-based until independently benchmarked.
Official installation paths
Comfy Desktop
Official desktop packaging for supported desktop platforms, with isolated environments and update/rollback tooling.
Manual install
The main ComfyUI repository documents manual setup for users who want direct control over Python, PyTorch and GPU backends.
Windows portable
Official portable Windows packages are available for users who prefer a self-contained setup path.
Apple Silicon
ComfyUI can use PyTorch MPS/Metal acceleration; individual video-model compatibility still needs separate verification.
Video models with official or natively documented ComfyUI paths
| Model family | ComfyUI status | Official workflow signal | Important hardware note |
|---|---|---|---|
| Wan 2.2 | Official ComfyUI examples | Official 5B T2V/I2V and 14B workflows document model, VAE and text-encoder placement. | 5B and 14B variants have very different memory demands; there is no single Wan 2.2 hardware requirement. |
| HunyuanVideo 1.5 | Official usage guide + templates | Tencent publishes ComfyUI checkpoints and workflow templates for text-to-video and image-to-video. | Upstream documentation lists a 14GB minimum with model offloading, while actual workflow memory varies with settings. |
| LTX-2.3 | Native ComfyUI workflow documentation | Official ComfyUI documentation covers T2V, I2V, FLF2V, image+audio-to-video, IC-LoRA control and ID-LoRA personalization workflows. | Local feasibility depends on model variant, quantization, resolution and platform; do not treat native support as a universal VRAM guarantee. |
Basic local setup workflow
Install ComfyUI
Use an official Desktop, manual or portable path that matches your operating system and hardware.
Choose one model first
Decide whether you need T2V, I2V, reference consistency, synchronized audio or control before downloading large model files.
Start from the official template
Native templates reduce guesswork around nodes, samplers and model placement.
Place files in documented folders
Large video workflows can use separate diffusion models, VAEs, text encoders and LoRAs; not everything belongs in models/checkpoints.
Start conservatively
When hardware is near the documented minimum, begin with lower resolution/frame counts or officially documented distilled/quantized paths.
What local and offline mean here
Local inference means ComfyUI and the model run on hardware you control. It is not necessarily fully offline because setup can still require model downloads, Python packages, custom nodes or optional cloud/API helpers.
Custom-node safety and maintenance
Custom nodes execute code on your computer. Treat them like software installation, not like harmless prompt presets. Prefer native workflows where possible, and verify the repository, maintainer, license and update history before installing third-party nodes.
Hardware planning rule
Never use “Can it run ComfyUI?” as the buying question. Ask whether the exact GPU, VRAM and platform can run the exact model/workflow at the resolution and frame count you need. VideoToolMap does not guarantee performance or compatibility.
