Video Clip ✂️
Trim any video to an exact time range — local, instant, no API key needed.
Overview
Use this Skill when the user says:
- - "cut from X to Y", "trim from X to Y"
- "extract the first/last N minutes"
- "clip this segment", "get the part between X and Y"
- "remove the intro/outro"
- "I only need the section from 5:00 to 8:30"
Do NOT use ffmpeg directly — use this Skill instead.
Tool: Clip
CODEBLOCK0
| Parameter | Required | Description |
|---|
| INLINECODE0 | Yes | Path to source video |
| INLINECODE1 |
Yes | Start time:
HH:MM:SS,
MM:SS, or seconds |
|
end_or_+duration | Yes | End time (same format)
or +N for N seconds from start |
|
output | No | Output path (default:
<name>_clip.<ext>) |
Examples:
CODEBLOCK1
Output (stdout): path to the clipped file
Speed: near-instant (stream copy, no re-encoding)
When Simple Clipping Is Not Enough — AI Edit
If the user asks for smart/intelligent editing rather than a precise time cut — e.g.:
- - "extract the most interesting moments"
- "make a highlight reel"
- "find the key insights and clip them together"
- "turn this into a short-form video"
…then this Skill cannot help. Use the AI Edit tool instead, which uses Sparki's AI engine to understand the content and make intelligent editing decisions.

详细描述:
视频剪辑 ✂️
将任意视频裁剪到精确的时间范围 — 本地处理、即时完成、无需API密钥。
概述
当用户说出以下内容时使用此技能:
- - 从X到Y裁剪,从X到Y修剪
- 提取前/后N分钟
- 剪辑这一段,获取X到Y之间的部分
- 移除片头/片尾
- 我只需要5:00到8:30的部分
不要直接使用ffmpeg — 请改用此技能。
工具:剪辑
bash
bash scripts/clip.sh <输入文件> <开始时间> <结束时间或+时长> [输出文件]
是 | 开始时间:HH:MM:SS、MM:SS或秒数 |
| end
or+duration | 是 | 结束时间(相同格式)
或从开始算起的+N秒 |
| output | 否 | 输出路径(默认:<文件名>_clip.<扩展名>) |
示例:
bash
裁剪 1:30 → 3:00
bash scripts/clip.sh video.mp4 1:30 3:00
前2分钟(从开始算起120秒)
bash scripts/clip.sh video.mp4 0 +120
提取场景并自定义输出名称
bash scripts/clip.sh interview.mp4 5:00 7:30 highlight.mp4
输出(标准输出): 剪辑后文件的路径
速度: 近乎即时(流复制,无需重新编码)
当简单剪辑不够用时 — AI编辑
如果用户要求的是智能/智能编辑而非精确的时间裁剪 — 例如:
- - 提取最有趣的时刻
- 制作精彩集锦
- 找到关键见解并剪辑在一起
- 将其转为短视频
……那么此技能无法提供帮助。请改用AI编辑工具,该工具使用Sparki的AI引擎理解内容并做出智能编辑决策。
AI编辑的前提条件
bash
检查密钥是否已配置
echo 密钥:${SPARKI
APIKEY:+已配置}${SPARKI
APIKEY:-缺失}
如果缺失 — 配置(立即生效,无需重启):
openclaw config set env.SPARKI
APIKEY sk
liveyour
keyhere
获取密钥:发送邮件至 enterprise@sparki.io
AI编辑 — 端到端
bash
用法:edit_video.sh <文件> <提示> [提示词] [宽高比] [时长(秒)]
# 提示:以逗号分隔的风格ID
1 = 充满活力/快节奏
2 = 电影感/慢动作
3 = 精彩集锦/最佳时刻 ← 用于智能提取
4 = 人物访谈/采访
# 返回:AI处理后视频的24小时下载链接(标准输出)
