Video Full Process

Video Full Process Skill

Combines video-clean and video-add-chapters into a single workflow that:

• Transcribes once (saving API costs)
• Removes pauses and filler words
• Detects and embeds chapters
• Remaps chapter timestamps to the cleaned video
• Generates YouTube chapter markers and documentation

When to Use This Skill

• Processing raw video recordings end-to-end
• Creating polished videos with embedded chapters
• Generating YouTube-ready content with chapter markers
• When you need both pause removal AND chapter organization

Quick Start

# Full processing with default settings
python process_video.py "video.mp4" --language ko

# Preview mode (see what will be changed)
python process_video.py "video.mp4" --preview

# Skip chapter embedding (only clean + generate docs)
python process_video.py "video.mp4" --no-embed-chapters

Output Files

Requirements

System

• Python 3.7+
• FFmpeg (for video processing)

Python Packages

pip install openai

Environment Variables

• OPENAI_API_KEY - Required for Whisper API

Detailed Usage

Full Processing

python process_video.py "presentation.mp4" --language ko

This runs:

1. Transcription (if not exists)
2. Chapter detection
3. Pause removal
4. Chapter remapping
5. Chapter embedding
6. Documentation generation

Partial Processing

# Skip transcription (reuse existing)
python process_video.py "video.mp4" --skip-transcribe

# Skip cleaning (only add chapters)
python process_video.py "video.mp4" --skip-clean

# Skip chapter embedding (only clean + generate docs)
python process_video.py "video.mp4" --no-embed-chapters

Customization

# Adjust pause threshold
python process_video.py "video.mp4" --pause-threshold 0.8

# Custom output directory
python process_video.py "video.mp4" --output-dir "./output"

Chapter Remapping Logic

When pauses are removed, chapter timestamps must be adjusted:

Original Video:
|--Ch1--|--pause--|--Ch2--|--pause--|--Ch3--|
0       30        40      60        70      90

Cleaned Video (pauses removed):
|--Ch1--|--Ch2--|--Ch3--|
0       30      50      70

Remapping:
- Ch1: 0 → 0 (no change)
- Ch2: 40 → 30 (10s pause removed before)
- Ch3: 70 → 50 (20s total pauses removed before)

The remap_chapters.py script handles this automatically using the pause data from video cleaning.

Integration with Existing Skills

This skill orchestrates two existing skills:

video-clean (.claude/skills/video-cleaning/)

• Provides: transcribe_video.py, edit_video_remove_pauses.py
• Modified: Added --output-pauses flag

video-add-chapters (Settings/Skills/video-add-chapters/)

• Provides: transcribe_video.py, suggest_chapters.py, generate_docs.py
• Modified: Added --skip-if-exists flag

Cost Estimate

• Single transcription: ~$0.006/min (vs $0.012/min if running separately)
• 1-hour video: ~$0.36 (saves $0.36 by reusing transcript)

Troubleshooting

"Transcript not found" Error

Run transcription first or use --force-transcribe:

python process_video.py "video.mp4" --force-transcribe

"Chapter timestamps don't match"

Regenerate remapped chapters:

python remap_chapters.py "video - chapters.json" --pauses "video - pauses.json"

FFmpeg embed fails

Check that chapters.json format is correct:

{
  "chapters": [
    {"start": 0, "title": "Intro", "description": "..."},
    {"start": 120, "title": "Main", "description": "..."}
  ]
}
