Install and run

Setup complexity: low.

clawhub skill install s17emme0e2m3cpf7k2jvp3a84984b8z9:nm-scry-media-composition
  1. Setup complexity is classified as HIGH. You must provision dedicated cloud infrastructure or an isolated VM. Do not run this directly on your local workstation.
  2. Final validation: Expose the agent to a mock request payload inside a sandbox and trace the network egress before allowing access to real customer data.

Contract: missing

# Media Composition Skill

Combine multiple media assets (GIFs, videos, images) into composite outputs for detailed tutorials and documentation.


## When To Use

- Combining multiple media outputs into compositions
- Creating composite demos from terminal and browser recordings

## When NOT To Use

- Single-format output that does not need composition
- Simple terminal recordings - use scry:vhs-recording directly

## Overview

This skill orchestrates the combination of separately generated media assets into unified outputs. It reads manifest files that define components and their composition rules, validates all inputs exist, and executes FFmpeg commands to produce the final composite media.

## Required TodoWrite Items

```
- Parse composition manifest file
- Validate all component outputs exist
- Determine composition layout and parameters
- Execute FFmpeg composition command
- Verify combined output file created
- Report composition metrics (file size, dimensions)
```
**Verification:** Run the command with `--help` flag to verify availability.

## Manifest Format

Manifests define the components to combine and how to

## Description:

Combines GIFs and videos into composite tutorials with vertical or grid layouts via FFmpeg.

This skill is ready for commercial/non-commercial use.

## Publisher:

[athola](https://clawhub.ai/user/athola)

### License/Terms of Use:

MIT-0

## Use Case:

Developers and documentation authors use this skill to combine existing media assets into tutorial or demo compositions using manifest-defined layouts and FFmpeg commands.

### Deployment Geography for Use:

Global

## Known Risks and Mitigations:

Risk: Broad activation terms could cause the skill to be selected for generic media or tutorial requests.

Mitigation: Invoke it only for explicit media-composition tasks that require combining assets with FFmpeg.

Risk: Manifest-defined paths and prerequisite commands may point to unintended local files or commands.

Mitigation: Review the manifest paths and required commands before execution, then verify the intended output file after composition.

- [Clawdis homepage](https://github.com/athola/claude-night-market/tree/master/plugins/scry)

## Skill Output:

**Output Type(s):** [text, markdown, shell commands, configuration, guidance]

**Output Format:** [Markdown guidance with YAML manifest examples and FFmpeg shell commands]

**Output Parameters:** [1D]

**Other Properties Related to Output:** [Produces instructions for local media composition and output verification; the skill itself does not embed generated media.]

## Skill Version(s):

1.9.19 (source: server release metadata)

## Ethical Considerations:

Users should evaluate whether this skill is appropriate for their environment, review any generated or modified files before relying on them, and apply their organization's safety, security, and compliance requirements before deployment.
