Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

video-editing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

视频剪辑

用自然语言指令做通用视频处理。所有操作都调用共享脚本 skills/shared/scripts/video_ops.py(subprocess 封装 ffmpeg/ffprobe), 不要现场手拼 ffmpeg 命令——脚本已处理音画同步、字体路径、编码默认值、 错误捕获等易错点。

从项目根目录运行。脚本相对路径:skills/shared/scripts/video_ops.py。 每个子命令都支持 -h 查看参数。

输入

  • 视频文件路径 + 操作描述(用户没给路径就问)
  • 可选:目标平台/比例/时间段等参数

输出

处理后的视频/图片,存到 outputs/主题名/。脚本会打印 ✅ <路径> (大小)

与 clipify 的边界

  • clipify = 长视频智能切片 + 人脸追踪 pan + 逐字字幕烧录的特化流程。 需要"从长视频找精彩片段做成竖版短视频带字幕"时用它。
  • video-editing(本 SKILL) = 通用剪辑处理。单点操作或自由组合时用它。 不做人脸追踪、不做字幕烧录(那是 clipify)。

子命令速查

python skills/shared/scripts/video_ops.py info -i <视频> 看清源信息,再操作。

子命令 用途 关键参数
cut 按起止时间裁剪 --start --end/--duration--reencode 精确裁
concat 多段拼接 --mode demuxer(同参数无损)/filter(异参数统一)
speed 变速(音画同步) --factor 2.0
silence-cut 检测静音并去除(跳切) --noise -30 --min-silence 0.5 --pad 0.05(别名 mute-cut
text 文字覆盖 --text --position --fontsize --color --start --end --box
aspect 横竖比转换 --ratio 9:16 --mode pad(补边)/crop(裁切)
frame 抽帧做封面 --time 00:00:03 --width
gif 转 GIF --start --end --fps 12 --width 480
compress 压缩 --crf 26--bitrate 2M--scale 降分辨率
bgm 加背景音乐混音 --music --voice-volume 1.0 --music-volume 0.3
watermark 加图片水印 --logo --position --width --opacity
info 时长/分辨率/帧率/码率(json) -i

text / watermark 位置七选一:center top bottom top-left top-right bottom-left bottom-right。中文字体自动探测(wqy-microhei / Noto CJK), 也可 --font 显式指定。

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
