SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill turns raw footage into a coherent edited video by forcing a deterministic, evidence-driven pipeline for cutting, assembling, and optional programmatic polishing instead of relying on subjective “looks right” edits.

Core Features & Use Cases

  • Automated, EDL-driven cutting: Converts a transcript into an edit decision list (EDL) and executes FFmpeg cuts in EDL order to prevent concat/order mistakes.
  • Deterministic assembly with hard gates: Captures, verifies intermediate artifacts (transcripts, EDL, segments, rough cut), and blocks progress when required outputs are missing.
  • Optional Remotion composition layer: Wraps the assembled rough cut into a Remotion TypeScript/TSX workflow for timed overlays (titles, lower-thirds, captions) when needed.
  • Optional gap-filling assets generation: Generates only missing assets (e.g., voiceover via ElevenLabs; b-roll/music via fal.ai) when the source coverage is insufficient.

Use Case Example: Create a 60–90 second product demo vlog by transcribing a screen recording, selecting narrative cut points, rendering FFmpeg segments, concatenating them into a rough cut, and then using Remotion to add timed titles and lower-thirds.

Quick Start

Use the video-editing skill to convert your screen recording into an edited vlog by generating cuts.txt from a transcript, producing assembled/rough-cut.mp4 with FFmpeg, and writing handoff-notes.txt for final human taste and export.

FAQPage Schema
How do I automate video editing from a transcript into an EDL?

Yes, Remotion composition works with FFmpeg rough cuts by wrapping the assembled video into a TypeScript/TSX workflow. This allows you to apply timed programmatic overlays like titles, lower-thirds, and captions onto the deterministic base cut.

Can I generate missing voiceover or b-roll assets during video assembly?

Missing voiceover or b-roll assets are generated conditionally only when source coverage is insufficient. The pipeline can gap-fill assets using ElevenLabs for voiceover generation and fal.ai for b-roll or music to complete the video assembly.

What are the prerequisites for running a deterministic FFmpeg video cutting pipeline?

Running a deterministic FFmpeg cutting pipeline requires preflight dependency checks and an EDL-first gating mechanism. The system verifies that intermediate artifacts, including the transcript, EDL, segments, and rough cut files, actually exist on disk before allowing progress to the next stage.

When should I use an EDL-driven video pipeline instead of manual editing?

An EDL-driven video pipeline is best for demo videos, vlogs, and screen-recording workflows where AI-driven judgment determines cut boundaries. It replaces subjective manual editing with an evidence-driven process that captures and verifies intermediate artifacts to prevent concat errors.
