Add comprehensive WebM to MP4 conversion documentation to help users convert high-quality YouTube downloads to more widely compatible MP4 format. Changes: - Add "Convert WebM to MP4" section to Common Tasks with ffmpeg workflow - Include detailed parameter explanations (H.264, AAC, CRF, preset) - Add conversion use case to "When to Use This Skill" section - Document encoding speed expectations (~6x on modern hardware) - Maintain imperative form throughout new content The workflow guides users through: 1. Installing ffmpeg if needed 2. Converting WebM (VP9) to MP4 (H.264/AAC) with optimal settings 3. Understanding quality/speed tradeoffs This addresses the common need to convert high-quality YouTube downloads (which use WebM/VP9 by default) to MP4 format for better device compatibility. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
