What it does
面向音频、视频或图片素材组成成片的编辑制作目标，适用于时间线裁剪与拼接、速度和音量调整、视频滤镜、运镜特效、转场、画面裁切旋转翻转、字幕压制、局部模糊、动图截取、淡入淡出、音视频提取与合流、音频混合以及多画面空间组合等操作。若用户要给视频添加滤镜、春日/晚霞/鲜亮/白皙/食物等滤镜效果，或对象和目标族已明确是对现有素材做剪辑、合成、混合或成片编排，但具体做法不确定，可先加载本 Skill 探索；若只给出媒体类型而未说明要剪、合、调、加滤镜还是分析，应先澄清。纯图像增强、抠图、OCR、图片水印或图片体积治理应路由到 image；视频画质增强、内容理解、字幕擦除、暗水印、人像或绿幕抠像等视频智能处理应路由到 video；音频转码、语音端点检测、人声背景分离等非剪辑目标应路由到 audio。
Installed, it changes the agent in these ways.
What this skill changes about the agent has not been set out here as a list. Its SKILL.md, shown below, says it in the author’s own words.
And these are the jobs people reach for it for.
The skill itself
A skill is instructions the model reads, so you can see what you are getting: below is the start of its SKILL.md. The front matter loads with every session, the body loads when the skill triggers, and the whole file comes with the install.
Nothing in a skill executes. The client loads the text and the model follows it, so a skill can be audited the way a runbook is — by reading it.
What it costs in context
Skills are not billed by the call. They are paid for in context: every token the instructions occupy is a token your code, your diff and your conversation cannot use. Here is what this one takes and when it takes it.
28.9k tokens, estimated from the bundle at four bytes to the token, held for the rest of the session once it triggers. Heavy. Teams tend to install this one per project rather than globally, and load it only when the job comes up.
A server charges by the month. A skill charges once per session, in context, and then keeps charging it for as long as the session lives.
Before and after
The same question, put to the same model twice: once as it comes, and once with these instructions loaded.
No worked example has been published for this skill yet.
The procedure it runs
The procedure has not been set out here step by step. It is in the body of its SKILL.md: the start of it is shown above, and the whole file comes with the install.
These steps are written for a model to follow, not executed by a runtime. It can still be told to skip one, and it will say so when it does.
Servers it uses
None. This skill calls no MCP servers at all.
Everything it needs is in the instructions, so it works in a project with nothing connected — the model reads the file and changes how it works with what it can already reach.
Its SKILL.md does not declare which tools it asks the agent for, so what it touches is whatever the instructions themselves ask for — read them before you install it.
This SKILL.md carries no allowed-tools line, so neither is declared. A skill grants no permissions of its own — it can only ask for tools your client already has.
What it will not do
Every skill is narrow, and the useful ones say where they stop. These are the jobs this one is the wrong tool for.
What this skill is not for has not been published here. Nothing is implied by that: it is a section the author has not filled in.
What is in the bundle
22 files, 115.8 kB on disk. A bundle is text throughout: the instructions the model reads, plus the templates it fills in.

No dependencies and nothing executable: a skill is text the agent reads, so the bundle is 22 files you can review in full before installing. The MIT licence covers the templates and examples as well as the instructions.
Install
Installing copies the bundle into your project. Nothing runs at install time — the files sit on disk until the model reads them.

Run Set-ExecutionPolicy -Scope CurrentUser RemoteSigned once, or type npx.cmd instead of npx (codex.cmd, gemini.cmd, grok.cmd likewise). PowerShell 7 needs neither. Writes to .claude/skills/bytedance-mediakit-video-audio-editor/ in the current project. For every project instead, run mkdir -p ~/.claude/skills && t=$(mktemp -d) && curl -fsSL -o "$t/bundle.tar.gz" https://mcprush.com/api/skills/bytedance-mediakit-video-audio-editor/bundle.tar.gz && tar -xzf "$t/bundle.tar.gz" -C "$t" && [ -d "$t/bytedance-mediakit-video-audio-editor" ] && { [ ! -e ~/.claude/skills/bytedance-mediakit-video-audio-editor ] || { mv ~/.claude/skills/bytedance-mediakit-video-audio-editor "$t/.previous" && echo "Previous copy moved to $t/.previous"; }; } && mv "$t/bytedance-mediakit-video-audio-editor" ~/.claude/skills/ && echo "Installed ~/.claude/skills/bytedance-mediakit-video-audio-editor" (macOS, Linux) — or add --global to the npx line. The curl line replaces .claude/skills/bytedance-mediakit-video-audio-editor/ only after the download succeeds, so files left there by another skill of the same name, or by an older release, do not mix in. A copy already there is moved aside, not deleted, and the line prints where. It appears as byted-mediakit-editing in Gemini CLI, Codex, Copilot and Grok (its own name); Claude Code lists it by the folder name, bytedance-mediakit-video-audio-editor.
Which clients pick it up on their own
A skill is a folder of text. Most of these read a skills folder and pick it up without being told; the rest take the same folder another way — an upload in the app, a parameter on an API call — and then choose it by its description just the same.
Versions
v0.2.1 is what is on the shelf; no release here carries a date. Instructions change more often than APIs do — a skill can be rewritten entirely without anything it depends on moving.
- No earlier releases have been published to the marketplace.
The install command always fetches the release that is current the day you run it — v0.2.1 today — and cannot ask for an earlier one. The copy on your disk does not change until you run it again.
Reviews
Nobody has reviewed this skill yet. The rating is the mean of the reviews written here, so there is none until somebody writes the first.
A review is tied to an account so it can be answered, edited and taken down by the person who wrote it.
