video-edit

Original：🇺🇸 English

Translated

Edit existing video on RunComfy — this skill is a smart router that matches the user's intent to the right edit model in the RunComfy catalog. Picks Wan 2.7 Edit-Video (general restyle / background swap / packaging swap, identity + motion preservation), Kling 2.6 Pro Motion Control (transfer precise motion from a reference video to a target character), or Lucy Edit Restyle (lightweight identity-stable restyle / outfit swap). Bundles each model's documented prompting patterns so the skill gets sharper edits without burning iterations on the wrong model. Calls `runcomfy run <vendor>/<model>/<endpoint>` through the local RunComfy CLI. Triggers on "video edit", "edit video", "restyle video", "swap video background", "motion control", "outfit swap video", or any explicit ask to transform a video.

Video Edit — Pro Pack on RunComfy

runcomfy.com · Wan 2.7 Edit-Video · Kling Motion-Control Pro · Lucy Edit Restyle · GitHub

Video edit, intent-routed. This skill doesn't lock you to one model — it picks the right video-edit model in the RunComfy catalog based on what the user actually wants: general restyle, motion transfer from a reference clip, or lightweight identity-stable outfit / background swap.

bash

npx skills add agentspace-so/runcomfy-skills --skill video-edit -g

Pick the right model for the user's intent

User intent	Model	Why
Restyle a talking-head video — preserve face / pose / lip movement	Wan 2.7 Edit-Video	Strong identity + motion preservation; supports up to 1080p
Swap product background, keep camera motion	Wan 2.7 Edit-Video	Camera motion preserved; one-direction edit honored
Replace packaging design using a reference image	Wan 2.7 Edit-Video + `reference_image`	Reference-conditioned design transfer
Apply cinematic color grade / commercial polish	Wan 2.7 Edit-Video	Good at single-direction global look changes
Transfer precise motion from a reference video to a target character	Kling 2.6 Pro Motion Control	Designed for motion mapping with identity hold
Lip-sync motion of a target character to source video's lip movement	Kling 2.6 Pro Motion Control	Built for tight temporal coherence
Lightweight outfit / costume swap with identity preservation	Lucy Edit Restyle	Core strength is localized identity-stable edits
Identity-stable restyle ("astronaut in desert", "warm golden-hour lighting")	Lucy Edit Restyle	Specializes in temporal consistency for restyle
Default if unspecified	Wan 2.7 Edit-Video	Most versatile, highest resolution

The agent reads this table, classifies the user's intent, and picks the matching subsection below.

Prerequisites

RunComfy CLI —
```
npm i -g @runcomfy/cli
```
RunComfy account —
```
runcomfy login
```
.
CI / containers — set
```
RUNCOMFY_TOKEN=<token>
```
.
A source video URL — formats and limits depend on the chosen route.

Route 1: Wan 2.7 Edit-Video — default for restyle / background / packaging

Model:

wan-ai/wan-2-7/edit-video

Schema

Field	Type	Required	Default	Notes
`prompt`	string	yes	—	Lead with preservation. One edit direction per call.
`video`	string	yes	—	MP4/MOV URL, 2–10s, ≤100MB.
`reference_image`	string	no	—	URL — use for direct design / appearance transfer only.
`resolution`	enum	no	(input)	`720p` or `1080p` .
`aspect_ratio`	enum	no	(input)	W:H. Defaults to input.
`duration`	int	no	0	`0` = match input; `2–10` = truncate from start.
`audio_setting`	enum	no	`auto`	`auto` or `origin` (preserve source audio).
`seed`	int	no	—	Reproducibility.

Invoke

Background swap, identity preserved, audio kept:

bash

runcomfy run wan-ai/wan-2-7/edit-video \
  --input '{
    "prompt": "Preserve the speaker'\''s face, pose, and lip movement; change the background to a modern office with neutral lighting.",
    "video": "https://.../speaker.mp4",
    "audio_setting": "origin"
  }' \
  --output-dir <absolute/path>

Packaging swap with reference image:

bash

runcomfy run wan-ai/wan-2-7/edit-video \
  --input '{
    "prompt": "Maintain the original framing and hand movement; replace the packaging design using the reference image.",
    "video": "https://.../hand-holding-package.mp4",
    "reference_image": "https://.../new-packaging.png",
    "audio_setting": "origin"
  }' \
  --output-dir <absolute/path>

Prompting tips

Preservation goals first:

"Preserve [face / pose / motion / framing / lip movement]; [then state the change]"

.

One edit direction per call. Compound edits drift on motion.
reference_image
only when justified (packaging swap, costume swap with target visual). Don't pass refs for general restyle.
audio_setting: "origin"
for talking-head where you don't want soundtrack regenerated.
Source video constraints: 2–10s, ≤100MB.

Route 2: Kling 2.6 Pro Motion Control — when motion FROM a reference clip is the point

Model:

kling/kling-2-6/motion-control-pro

Use when the user wants to transfer the motion of a reference video onto a target character (driven by an image OR another video). This isn't restyle — it's motion mapping with identity hold.

Schema

Field	Type	Required	Notes
`prompt`	string	yes	Describe target motion / style.
`image`	string	yes (image orientation)	Reference for character / background consistency.
`video`	string	yes	Motion reference. 10–30s depending on orientation.
`keep_original_sound`	bool	no	Preserve audio from reference video.
`character_orientation`	enum	yes	`image` (max 10s output) or `video` (max 30s output).

Invoke

bash

runcomfy run kling/kling-2-6/motion-control-pro \
  --input '{
    "prompt": "A young american woman dancing",
    "image": "https://.../target-character.jpg",
    "video": "https://.../motion-reference-dance.mp4",
    "character_orientation": "image",
    "keep_original_sound": true
  }' \
  --output-dir <absolute/path>

Prompting tips

Subject must be > 5% of frame in the image reference for clean identity hold.

Spatial constraints help:

"character on left side, background motion right"

.

Simplify if results drift between iterations — drop adjectives, keep core motion description.
character_orientation: "image"
caps output at 10s;
```
"video"
```
allows 30s.

Route 3: Lucy Edit Restyle — lightweight identity-stable restyle / outfit swap

Model:

decart/lucy-edit/restyle

Use when the edit is localized style modification — outfit swap, scene relight, atmospheric restyle — and identity preservation is critical. Lighter-weight than Wan 2.7 Edit; capped at 720p.

Schema

Field	Type	Required	Default	Notes
`prompt`	string	yes	—	Natural-language edit instruction.
`video_url`	string	yes	—	MP4/MOV/WEBM/GIF.
`resolution`	enum	no	`720p`	`720p` only on this tier.

Invoke

Outfit swap:

bash

runcomfy run decart/lucy-edit/restyle \
  --input '{
    "prompt": "Change outfit to professional business attire; preserve face and motion.",
    "video_url": "https://.../subject-walking.mp4"
  }' \
  --output-dir <absolute/path>

Atmospheric restyle:

bash

runcomfy run decart/lucy-edit/restyle \
  --input '{
    "prompt": "Make lighting warm and golden hour; preserve face, pose, and motion.",
    "video_url": "https://.../subject-portrait.mp4"
  }' \
  --output-dir <absolute/path>

Prompting tips

Localized change phrasing wins. "Outfit", "lighting", "background" — pick one bucket.
Preserve identity goals —
```
"preserve face and motion"
```
is enough; don't over-specify.
Avoid total replacement ("astronaut in space" works; "swap subject for a different person" doesn't). Lucy is built for localized style mods, not full character swap.
No aspect ratio control — output matches input. Cropping happens server-side if you don't pre-match.

Limitations

Each route inherits its model's limits. Wan 2.7 Edit: 2–10s, 1080p ceiling. Kling: 10s (image orientation) or 30s (video orientation). Lucy: 720p ceiling, no aspect control.
No multi-route blending. This skill picks one model per call.
Brand-specific overrides — if the user named a specific model, route to the corresponding brand skill (
```
wan-2-7
```
) for fuller treatment.

How it works

The skill picks one of Wan 2.7 Edit-Video / Kling 2.6 Pro Motion Control / Lucy Edit Restyle based on user intent and invokes

runcomfy run <model_id>

with the matching JSON body. The CLI POSTs to the Model API, polls the request, fetches the result, and downloads any

.runcomfy.net

/

.runcomfy.com

URL into

--output-dir

.

Ctrl-C

cancels the remote request before exit.

Security & Privacy

Token storage:
```
runcomfy login
```
writes the API token to
```
~/.config/runcomfy/token.json
```
with mode 0600 (owner-only read/write). Set
```
RUNCOMFY_TOKEN
```
env var to bypass the file entirely in CI / containers.
Input boundary: the user prompt is passed as a JSON string to the CLI via
```
--input
```
. The CLI does NOT shell-expand the prompt; it transmits the JSON body directly to the Model API over HTTPS. No shell injection surface from prompt content.
Third-party content: image / mask / video URLs you pass are fetched by the RunComfy model server, not by the CLI on your machine. Treat external URLs as untrusted; image-based prompt injection is a known risk for any image-edit / video-edit model.
Outbound endpoints: only
```
model-api.runcomfy.net
```
(request submission) and
```
*.runcomfy.net
```
/
```
*.runcomfy.com
```
(download whitelist for generated outputs). No telemetry, no callbacks.
Generated-file size cap: the CLI aborts any single download > 2 GiB to prevent disk-fill from a malicious or runaway model output.
