Video Edit
Edit videos locally with ffmpeg commands—trim, concat, resize, compress, and convert
What You Can Do
You can perform professional-grade video editing operations entirely on your machine using ffmpeg. Cut segments from videos, join multiple clips together, resize for social platforms (TikTok, Instagram, YouTube), adjust playback speed, extract or replace audio tracks, compress files for storage, and convert between formats—all with copy-paste ffmpeg commands that Claude generates based on your specific requirements.
Features
Example Output
Example 1: Trim a video
ffmpeg -y -ss 00:00:30 -to 00:01:45 -i video.mp4 -c copy trimmed.mp4
Creates a 1-minute 15-second clip starting at 30 seconds into the original video.
Example 2: Resize for TikTok
ffmpeg -y -i video.mp4 -vf "scale=1080:1920:force_original_aspect_ratio=decrease,pad=1080:1920:(ow-iw)/2:(oh-ih)/2:black" tiktok.mp4
Resizes to 1080×1920 with black letterboxing to maintain aspect ratio.
Example 3: Concatenate clips
printf "file '%s'\n" clip1.mp4 clip2.mp4 clip3.mp4 > list.txt
ffmpeg -y -f concat -safe 0 -i list.txt -c copy joined.mp4
Joins three video files seamlessly into a single output.

Build detailed, shoot-ready plans that anticipate technical challenges and capture decisive moments under pressure. You'll generate venue-specific shot lists tailored to unique logistics, develop contingency workflows for unpredictable conditions (weather, lighting, timing delays), and coordinate multi-team coverage with clear positioning and equipment redundancy strategies. This skill transforms vague event briefs into actionable pre-production blueprints that keep you organized and confident on-set.

You'll develop systematic viral video strategies grounded in platform algorithms and audience psychology rather than guesswork. Analyze trending patterns, audience demand signals, and engagement metrics to create content calendars designed for maximum views, shares, and monetization. Move from reactive content creation to proactive strategic planning that justifies every creative decision with data.

Systematically troubleshoot failing simulations by identifying root causes in solver instability, constraint errors, cache corruption, and performance bottlenecks. You'll receive targeted diagnostic workflows, parameter tuning strategies, and rebuild recommendations that save render farm resources and maintain deadline adherence. This skill acts as your technical partner when simulations produce artifacts, crash mid-cache, or consume excessive memory.

Transform raw video analytics into platform-specific optimization plans that boost reach and engagement. You'll identify why certain videos outperform others, uncover trending patterns in your niche, optimize metadata and technical specs for algorithmic distribution, and systematically test creative approaches. This skill bridges creative instinct with data-driven decision-making to help you scale social video performance.

You can diagnose root causes of cloth simulation failures—clipping, jittering, unrealistic wrinkles, and instability—by sharing solver logs, simulation parameters, and fabric behavior descriptions with Claude. The skill generates actionable debugging strategies and optimization techniques that preserve visual quality while reducing iteration cycles and compute time across Maya nCloth, Houdini, Marvelous Designer, and other industry solvers.

You'll design dynamic audio systems that shift music and sound effects in real-time based on gameplay intensity, player decisions, environmental conditions, and narrative branching. This skill guides you through building adaptive mixing strategies, stem-based music systems, and procedural audio routing that keeps audio responsive without becoming chaotic—allowing you to maximize asset reusability while maintaining sonic coherence across unpredictable gameplay states.

This skill helps you architect complete color strategies before grading sessions begin. You'll generate detailed shot-by-shot grading maps that synchronize visual mood to dynamic audio, develop LUT strategies for specific music genres with documented creative reasoning, establish technical parameter ranges per scene or musical section, and create mood board documentation that aligns stakeholder expectations early. By treating color as a primary creative element rather than post-production cleanup, you reduce revision cycles and deliver grades that amplify both narrative and musical intent.
