Run frontier video models — Sora 2, Veo 3.1, Kling 3.0, Seedance, MiniMax H3 — inside your ComfyUI workflow, plus face swap and hosted image generation. No GPU needed; everything renders on Magic Hour's infrastructure.

These models can't run locally. This node puts them in your graph next to everything that can.

Nodes

| Node | In | Out | |---|---|---| | Magic Hour · Text to Video | prompt | video path | | Magic Hour · Image to Video | IMAGE + prompt | video path | | Magic Hour · Image Generator | prompt | IMAGE | | Magic Hour · Face Swap (Photo) | 2× IMAGE | IMAGE |

Video nodes write an .mp4 into your ComfyUI output folder and return its path.

Install

ComfyUI Manager: search "Magic Hour" → install.

Manually:

cd ComfyUI/custom_nodes
git clone https://github.com/YOUR_GITHUB/comfyui-magic-hour

Restart ComfyUI.

Models

Labels in the dropdown tell you the plan you need and what each model is for.

Free plan

| Model | Credits/sec | Durations | Notes | |---|---|---|---| | wan-2.2 | 24 | 3–15s | physics & camera motion | | ltx-2.3 | 24 | 1–30s | fastest, good for iterating | | minimax-h3 | 24 | 1–30s | native audio, max 1080p |

Paid plans

| Model | Credits/sec | Durations | Notes | |---|---|---|---| | seedance-1.5 | 30 | 4–12s | smooth, precise motion | | kling-2.6 | 36 | 5 or 10s | action & motion blur | | kling-3.0 | 48 | 3–15s | best cinematic, up to 4k | | veo3.1-lite | 48 | 4–56s | Veo quality, cheaper | | seedance-2.0-mini | 96 | 4–15s | max 720p | | veo3.1 | 96 | 4–56s | highest realism | | veo3.1-audio | 96 | 4–56s | Veo + native audio | | sora-2 | 120 | 4/8/12/24/36/48/60s | max 720p | | seedance-2.0 | 144 | 4–15s | reference-to-video, max 720p | | seedance-2.5 | 288 | 4–30s | best quality, max 720p |

Resolution

Gated by plan, not by model:

| Resolution | Plan | |---|---| | 480p | Free | | 720p | Creator+ | | 1080p | Pro+ | | 4k | Business |

If you pick something above your plan, the node steps down and retries rather than failing — you get a video and a note in the console.

Behaviour worth knowing

Invalid durations are corrected, not rejected. Every model accepts a different set of clip lengths; ask Sora for 10 seconds and you get 8, with a console note.
Cost is printed before each run, e.g. wan-2.2 · 5s · 480p = ~120 credits.
Failed jobs are auto-refunded by Magic Hour — an error costs you nothing.
Nodes block while polling. A 5s clip usually lands in about a minute; longer or higher-res takes more.
Model list changes often. If something new appears in the web app, add it to VIDEO_MODELS and MODEL_CONSTRAINTS in nodes.py.
