Media Hub
Unified audio and video processing, transcription, and understanding.
When to Use
Use this skill when:
- Processing audio or video files for transcription or conversion
- Generating subtitles or speech-to-text output
- Extracting frames or clips from video content
- Performing batch media operations or format conversions
Do NOT use this skill if:
- The task is creating presentation slides → use pitch-deck-creator
- The task requires map or location data → use amap-navigator
- You only need simple file copying without media analysis
Typical triggers:
- 「视频转文字」「音频转录」「生成字幕」
- "transcribe video", "convert media format", "audio to text"
- "extract video frames", "batch process audio", "媒体转换"
Workflow
Step 1: Ingest Media
Accept input via:
- File path to local audio/video
- URL to downloadable media
- Existing media directory for batch processing
Step 2: Select Operation
Choose the appropriate processing mode:
- Transcription — speech-to-text with speaker diarization (optional)
- Format Conversion — re-encode to mp3, mp4, wav, webm, etc.
- Frame Extraction — capture keyframes at intervals or timestamps
- Subtitle Generation — produce SRT/VTT from transcribed audio
- Content Understanding — generate summaries or topic extraction from media
Step 3: Configure Parameters
- Source language for transcription (auto-detect if not specified)
- Output format and quality settings
- Target directory for processed files
- Batch size (for bulk operations)
Step 4: Execute Processing
Run the relevant pipeline and report progress:
Processing: filename.ext
- Transcoding: 45%
- Transcribing: 20%
Step 5: Deliver Results
Output files to a structured directory:
media-output/
├── transcript.txt / .srt / .vtt
├── converted/
├── frames/
└── summary.md
Guardrails
Anti-patterns
- NEVER process copyrighted content without user confirmation
- NEVER overwrite original source files; always output to a separate directory
- NEVER return extremely long raw transcripts without a summary or table of contents
Output Constraints
- Original files remain untouched
- Transcripts include timestamps when subtitles are requested
- Frame extractions include metadata (timestamp, resolution)
- Summaries are concise and structured
Error Handling
- Unsupported format: inform user and suggest conversion options
- Large files: split into chunks or request shorter segments
- Low-quality audio: flag accuracy warnings in transcription output
