任务目标
- 本 Skill 用于：处理视频和图像文件，进行格式转换、分辨率调整、压缩等操作
- 能力包含：
- 视频格式转换（MP4/AVI/MOV/MKV 等）
- 视频分辨率调整和压缩
- 图像格式转换（JPG/PNG/GIF/WebP 等）
- 图像分辨率调整和压缩
- 批量处理支持
- 触发条件：当用户需要处理视频或图像文件时触发
前置准备
- 依赖说明：本 Skill 依赖以下系统工具
- FFmpeg：视频处理工具
- ImageMagick：图像处理工具
- 系统依赖安装：Skill 首次使用时将自动安装系统依赖
apt-get update && apt-get install -y ffmpeg imagemagick
操作步骤
标准流程
- 需求分析
- 识别输入文件类型（视频/图像）
- 确定目标格式、分辨率、质量要求
- 评估是否需要批量处理
- 选择处理方式
- 视频处理：调用
scripts/中的视频处理脚本 - 图像处理：调用
scripts/中的图像处理脚本
- 执行处理
- 对于简单操作（如单一格式转换）：直接调用相应脚本
- 对于复杂操作（如多步骤处理）：智能体将调用多个脚本组合使用
- 结果验证
- 检查输出文件是否生成
- 验证文件格式和参数是否符合预期
常见操作指南
视频格式转换
- 调用
scripts/video_convert.py - 参数：input_path（输入路径）、output_path（输出路径）、output_format（目标格式）
- 示例：将 AVI 转换为 MP4
视频压缩
- 调用
scripts/video_compress.py - 参数：input_path、output_path、bitrate（目标码率）、crf（质量控制系数）
- 示例：压缩视频到 2Mbps
视频分辨率调整
- 调用
scripts/video_scale.py - 参数：input_path、output_path、width、height
- 示例：调整到 1920x1080
图像格式转换
- 调用
scripts/image_convert.py - 参数：input_path、output_path、output_format、quality
- 示例：将 PNG 转换为 JPG
图像缩放
- 调用
scripts/image_scale.py - 参数：input_path、output_path、width、height、maintain_aspect
- 示例：等比缩放到 1024x768
图像压缩
- 调用
scripts/image_compress.py - 参数：input_path、output_path、quality、method（压缩方法）
- 示例：质量设置为 85%
批量处理
- 当需要处理多个文件时，智能体将循环调用相应脚本
- 使用通配符模式匹配文件（如
*.avi、images/*.png） - 为每个文件生成对应的输出路径
资源索引
- 视频处理脚本：
- scripts/video_convert.py - 视频格式转换
- scripts/video_compress.py - 视频压缩
- scripts/video_scale.py - 视频分辨率调整
- 图像处理脚本：
- scripts/image_convert.py - 图像格式转换
- scripts/image_scale.py - 图像缩放
- scripts/image_compress.py - 图像压缩
- 参考文档：
- references/ffmpeg_guide.md - FFmpeg 参数参考（需要高级参数时读取）
- references/imagemagick_guide.md - ImageMagick 参数参考（需要高级参数时读取）
注意事项
- 确保输入文件路径正确，使用相对路径（
./开头） - 输出路径需要包含完整文件名和扩展名
- 质量参数范围：图像质量 1-100，视频 CRF 18-28（数值越小质量越高）
- 处理大文件时请耐心等待，智能体会持续监控执行状态
- 如果需要自定义参数（如编码器、帧率等），请参考相应参考文档
使用示例
示例1：视频格式转换
# 将 video.avi 转换为 video.mp4
python scripts/video_convert.py \
--input ./video.avi \
--output ./video.mp4 \
--format mp4
示例2：图像批量转换
# 将所有 PNG 转换为 JPG
for file in ./images/*.png; do
output="${file%.png}.jpg"
python scripts/image_convert.py \
--input "$file" \
--output "$output" \
--format jpg \
--quality 85
done
示例3：视频压缩与缩放
# 先缩放再压缩
python scripts/video_scale.py \
--input ./input.mp4 \
--output ./temp.mp4 \
--width 1280 \
--height 720
python scripts/video_compress.py \
--input ./temp.mp4 \
--output ./output.mp4 \
--bitrate 2M

Create beautiful visual art in .png and .pdf documents using design philosophy. You should use this skill when the user asks to create a poster, piece of art, design, or other static piece. Create original visual designs, never copying existing artists' work to avoid copyright violations.
Creating algorithmic art using p5.js with seeded randomness and interactive parameter exploration. Use this when users request creating art using code, generative art, algorithmic art, flow fields, or particle systems. Create original algorithmic art rather than copying existing artists' work to avoid copyright violations.
Improves the quality of images, especially screenshots, by enhancing resolution, sharpness, and clarity. Perfect for preparing images for presentations, documentation, or social media posts.
Create and edit JSON Canvas files (.canvas) with nodes, edges, groups, and connections. Use when working with .canvas files, creating visual canvases, mind maps, flowcharts, or when the user mentions Canvas files in Obsidian.
Publish Markdown articles to X (Twitter) Articles editor with proper formatting. Use when user wants to publish a Markdown file/URL to X Articles, or mentions "publish to X", "post article to Twitter", "X article", or wants help with X Premium article publishing. Handles cover image upload and converts Markdown to rich text automatically.
Downloads videos from YouTube and other platforms for offline viewing, editing, or archival. Handles various formats and quality options.
Teaches the AI to design like a high-end agency. Defines the exact fonts, spacing, shadows, card structures, and animations that make a website feel expensive. Blocks all the common defaults that make AI designs look cheap or generic.
Lightweight WSI tile extraction and preprocessing. Use for basic slide processing tissue detection, tile extraction, stain normalization for H&E images. Best for simple pipelines, dataset preparation, quick tile-based analysis. For advanced spatial proteomics, multiplexed imaging, or deep learning pipelines use pathml.
How to use it
Take anbeime/media-processor from the repository into ~/.claude/skills for personal
use, or into .claude/skills inside a project.
The agent identifies a skill by the name field in its header. Two skills with the
same name cannot sit side by side — one of them will be ignored.
The instructions reference apt.
Without those the skill loads but fails at the first command.
