SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Rapidly compresses, structure, and polish long-form raw video into concise, platform-ready edits so creators and teams avoid manual, repetitive cutting and assembly.

Core Features & Use Cases

  • Deterministic trimming and assembly: Generate FFmpeg commands and batch cuts to extract segments and assemble proxies for fast iteration.
  • Programmable composition and overlays: Produce Remotion compositions for reusable titles, lower thirds, and motion graphics.
  • Selective asset generation and polish: Integrate ElevenLabs/fal.ai for voiceover, music, and insert visuals, then hand off to Descript or CapCut for final taste-driven decisions.
  • Use Case: Turn a 4‑hour recorded tutorial into an edited 24‑minute vlog with highlights, narration, captions, and vertical social clips.

Quick Start

Ask the assistant to "Analyze this raw.mp4 transcript, identify the best eight segments for a 24-minute vlog, and return an edit decision list with FFmpeg cut commands and a Remotion composition plan."

Frequently Asked Questions about video-editing

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

FAQPage Schema
How do I automatically generate FFmpeg cut commands from a raw video transcript?

To generate FFmpeg cut commands from a raw video transcript, this process analyzes the transcript to identify key segments, then outputs an edit decision list with precise batch cut commands for deterministic trimming and fast proxy assembly.

What is the best way to turn a long tutorial into short vertical social clips?

The best way to turn long tutorials into short vertical social clips is using AI-assisted reframing and trimming, which structures raw footage into concise edits and produces Remotion compositions for platform-ready output.

Can I use ElevenLabs voiceover and fal.ai visuals in Remotion compositions?

Yes, you can integrate ElevenLabs voiceover and fal.ai insert visuals into Remotion compositions, generating polished assets programmatically before handing off the project for final taste-driven editing.

How does proxy editing work with FFmpeg batch cuts?

Proxy editing with FFmpeg batch cuts works by extracting specific segments from raw video into lower-resolution proxies, allowing for rapid iteration and structural assembly before finalizing the high-resolution render.

Do I need Descript or CapCut to finalize AI-assisted video edits?

You do not strictly need Descript or CapCut, but they are recommended for final taste-driven decisions after the AI generates the initial structure, transcripts, FFmpeg commands, and Remotion compositions.

When should I use Remotion compositions for video editing instead of manual cutting?

You should use Remotion compositions for video editing when you need reusable titles, lower thirds, and programmable motion graphics overlaid on your footage, rather than relying on manual cutting.
