Core capabilities

01

Talking-head cutting

Transcribes and identifies mistakes and retakes, produces a reviewable deletion ledger, and cuts only after confirmation.

02

Subtitles and visuals

Generates subtitles for the cut video and orchestrates visual emphasis and full-screen animation modules.

03

Final export

Uses the runtime for timeline, animated subtitles, and export, with frame-based review.

04

Safe support workflows

Sanitizes and deduplicates bug reports before user confirmation and checks pinned update sources without immediate replacement.

03

Installation and usage

Use the README's three Codex Marketplace commands to add the pinned commit, materialize the snapshot, and install the plugin. Before the first real edit, let the update/environment workflow download and hash-check the runtime and run doctor.

AI AGENT INSTALL

Let an AI Agent install it

Send this prompt to Codex, Claude Code, or another AI agent that can work with your local environment.

Help me install the chengfeng-videocut Codex Marketplace plugin from https://github.com/Agentchengfeng/chengfeng-videocut-skills. Read README.md, plugins/chengfeng-videocut/.codex-plugin/plugin.json, runtime-requirements.json, NOTICE.md, and LICENSE first. Use only the README's pinned Marketplace commit and official Codex CLI. Report and ask before touching an existing Marketplace, plugin, or runtime; do not overwrite state or delete caches manually. Perform read-only list checks after plugin installation. Ask again before downloading the runtime, starting services, opening Studio, editing footage, submitting a bug, or activating an update, and run doctor after runtime installation.
01Before you start
  • Codex plugin and Marketplace CLI support
  • Node.js 20+
  • The desktop bundle path, or Bun, FFmpeg/ffprobe, and Chrome prepared separately
  • Confirmation before installing the runtime, updating, or replacing state
02Copy the install command or configuration
codex plugin marketplace add Agentchengfeng/chengfeng-videocut-skills --ref 1487e02b1c0c39ea74d079e8ce45da56bf59bc32 && codex plugin marketplace upgrade chengfeng-videocut --json && codex plugin add chengfeng-videocut@chengfeng-videocut
03Complete the setup steps
  1. 1
    Review prerequisites and boundaries

    Read the repository installation material and confirm: Codex plugin and Marketplace CLI support; Node.js 20+; The desktop bundle path, or Bun, FFmpeg/ffprobe, and Chrome prepared separately; Confirmation before installing the runtime, updating, or replacing state. Stop for confirmation before credentials, cost, additional permissions, or replacement.

  2. 2
    Run the documented installation

    Use the current README command: codex plugin marketplace add Agentchengfeng/chengfeng-videocut-skills --ref 1487e02b1c0c39ea74d079e8ce45da56bf59bc32 && codex plugin marketplace upgrade chengfeng-videocut --json && codex plugin add chengfeng-videocut@chengfeng-videocut

  3. 3
    Run a minimal verification

    Run `codex plugin marketplace list --json` and `codex plugin list --json`, confirming the expected Marketplace and plugin version 0.10.8. Runtime installation requires separate user confirmation and a passing doctor check.

  4. 4
    Move to a real task

    After the minimal check passes, use nonsensitive test media first. Ask separately before external uploads, billable calls, publishing, or irreversible changes.

How to verify the setup

Run `codex plugin marketplace list --json` and `codex plugin list --json`, confirming the expected Marketplace and plugin version 0.10.8. Runtime installation requires separate user confirmation and a passing doctor check.

Before using it
  • The current repository is a Marketplace plugin rather than one standalone SKILL.md
  • Plugin installation and product runtime installation are separate; a listed plugin does not prove the editing environment is ready
  • Business workflows include human review and confirmation boundaries that must not be bypassed
  • No plugin, runtime, or footage was installed or processed for this catalog entry
04

Use cases

SCENARIO 01

Chinese talking-head rough cuts

Identify mistakes, retakes, and pauses, review a deletion ledger, then cut.

SCENARIO 02

Subtitles and packaging

Generate reviewed subtitles, emphasis treatments, and full-screen animation for cut footage.

SCENARIO 03

Trusted updates and issue reporting

Check updates from a pinned Marketplace source and sanitize and confirm GitHub issues before submission.

05

Assessment

Based on the README, installation material, and repository structure, chengfeng-videocut turns Talking-head cutting, Subtitles and visuals, Final export into explicit agent workflows. Its limitations are mainly dependency, host, and data-boundary concerns. This assessment is based on public material, without installation or a real media task.

Why it may be useful

  • Transcribes and identifies mistakes and retakes, produces a reviewable deletion ledger, and cuts only after confirmation.
  • Generates subtitles for the cut video and orchestrates visual emphasis and full-screen animation modules.
  • Uses the runtime for timeline, animated subtitles, and export, with frame-based review.

What to know first

  • The current repository is a Marketplace plugin rather than one standalone SKILL.md
  • Plugin installation and product runtime installation are separate; a listed plugin does not prove the editing environment is ready
  • Business workflows include human review and confirmation boundaries that must not be bypassed
  • No plugin, runtime, or footage was installed or processed for this catalog entry
