SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you turn long, raw recordings into polished short-form videos by performing fast, structured edits to existing footage rather than generating video from prompts.

Core Features & Use Cases

  • Deterministic cutting and assembling: Trim, extract, concatenate, and batch-produce segments from timestamp-based edit plans using FFmpeg.
  • Structured editing from transcripts: Use Gemini/Codex to transcribe, identify key segments, and produce an edit decision list that drives the cut plan.
  • Composable overlays and repeatable scenes: Use Remotion to add titles, lower-thirds, charts, motion graphics, and reusable templates consistently across videos.
  • Selective AI asset generation: Generate only missing assets such as voiceover (ElevenLabs) and supporting media/audio (fal.ai), then mix them into the final edit.
  • Final pacing and polish: Use Descript or CapCut to refine captions, audio mix, and export settings with human taste.

Quick Start

Ask the system: “Transcribe this recording, select the best 8 segments for a 24-minute vlog, and generate the FFmpeg cut commands to assemble the final video with overlays.”

Frequently Asked Questions about video-editing

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I automate cutting and assembling long raw video recordings into short-form vlogs?▼

Automate video editing by using transcripts and timestamps to generate an edit decision list, then apply deterministic FFmpeg commands to cut, extract, and concatenate segments into structured outputs.

Can I use FFmpeg to batch-produce video segments from a transcript-based edit plan?▼

Yes, FFmpeg executes deterministic edits by reading timestamp-based cut plans derived from transcripts, allowing you to trim, extract, and batch-produce multiple video segments automatically.

How do I add motion graphics and titles to existing footage programmatically?▼

Add programmable overlays like titles, lower-thirds, and charts to existing footage by composing repeatable scenes with Remotion templates across your structured video edits.

Does this video editing workflow support generating voiceovers and background music?▼

Yes, the workflow supports selective AI asset generation for missing media, allowing you to generate voiceovers and supporting audio, then mix them into the final edited composition.

What is the best way to reframe long tutorials into social-media ready videos?▼

The best way to reframe tutorials is transcribing the recording, identifying key segments, cutting the footage with FFmpeg, and applying Remotion overlays for social-media formats.

Do I need to manually refine captions and audio mix after automated video assembly?▼

Yes, after automated assembly, refine final pacing and polish captions, audio mix, and export settings using tools like Descript or CapCut to apply human taste.
