SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Turning hours of raw recordings into polished short-form videos requires tedious manual cutting, structuring, and asset creation. This Skill provides a layered AI-assisted pipeline that compresses, structures, and augments real footage instead of generating video from scratch. ## Core Features & Use Cases - Structured Editing Pipeline: Organize footage with Claude/Codex, cut deterministically with FFmpeg, compose overlays with Remotion, generate voiceover and music with ElevenLabs/fal.ai, and polish in Descript or CapCut. - Batch Cutting and Scene Detection: Use FFmpeg commands for timestamp extraction, concatenation, silence detection, and scene-change detection to auto-cut dead air. - Social Media Reframing: Convert 16:9 footage to 9:16 or 1:1 for TikTok, Reels, and Instagram using FFmpeg crops or VideoDB smart reframe. - Use Case: You have a 4-hour screen recording. Ask the AI to identify the 8 strongest segments, generate FFmpeg cut commands, assemble a 24-minute vlog, add a Remotion title overlay, and produce an ElevenLabs voiceover. ## Quick Start Use the video-editing skill to cut my raw recording into a short vlog with FFmpeg segments, Remotion overlays, and an ElevenLabs voiceover.

FAQPage Schema
How do I cut video segments by timestamp with FFmpeg?▼

Use ffmpeg -i raw.mp4 -ss 00:12:30 -to 00:15:45 -c copy segment.mp4 to extract a segment without re-encoding. For batch cuts, loop over a cuts.txt file containing start, end, and label values and run the same command per line.

How to convert 16:9 video to vertical 9:16 for TikTok?▼

Apply a center crop with FFmpeg: ffmpeg -i input.mp4 -vf "crop=ih*9/16:ih,scale=1080:1920" vertical.mp4. Alternatively, VideoDB offers a smart reframe mode with AI-guided subject tracking for moving subjects.

What is Remotion used for in video editing?▼

Remotion handles programmable composition: text overlays, lower thirds, data visualizations, transitions, and reusable scene templates written as React components. Render output with npx remotion render, then combine with FFmpeg-cut footage.

Can FFmpeg detect silence and scene changes automatically?▼

Yes. Use silencedetect=noise=-30dB:d=2 to find silent segments for cutting dead air, and select='gt(scene,0.3)' with showinfo to log scene-change timestamps. Feed these timestamps to an AI to plan highlight clips.

When should I not use AI video generation in editing?▼

This workflow is for editing real footage, not generating video from prompts. Generate selectively with ElevenLabs or fal.ai only for assets that do not exist, such as voiceover, music, or thumbnails, and keep real footage as the core.
