SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It eliminates the friction of producing videos by coordinating the end-to-end workflow—project setup, composition building, voiceover and music generation, and export—without leaving Claude.

Core Features & Use Cases

  • Video project orchestration: Starts or resumes a LiteEVA video project by scaffolding the required directory structure and launching Remotion Studio.
  • Scene-focused production: Generates voiceover per scene (ElevenLabs TTS or local fallback) and creates background music locally with ACE-Step.
  • Render and post-process/export: Renders Remotion compositions frame-accurately and uses FFmpeg for trimming, compression, and platform-ready exports.
  • Use case: Create a short marketing video that includes scene-by-scene narration, a cohesive soundtrack, and final exports for YouTube or TikTok.

Quick Start

Use the ls-eva skill to start a new video project by describing what you want to make and then requesting voiceover, music, render, and final export.

FAQPage Schema
How do I automate Remotion video production with voiceover and music generation?▼

Agentic video production scaffolds a Remotion project, generates per-scene TTS voiceover, creates local background music with ACE-Step, and renders final outputs using bundled Python tools and FFmpeg commands.

Can I generate TTS voiceover locally if ElevenLabs is unavailable for my video project?▼

Yes, when ElevenLabs TTS is unavailable, the workflow falls back to a local TTS server running on port 5123 to generate per-scene voiceover audio for your video project.

What is the best way to create background music locally for a Remotion composition?▼

Creating background music locally is handled by ACE-Step music generation, which produces a cohesive soundtrack directly within the agentic workflow alongside your Remotion composition and voiceover tracks.

How do I export Remotion compositions to platform-ready videos for YouTube or TikTok?▼

Export Remotion compositions by rendering them frame-accurately, then applying FFmpeg post-processing for trimming, compression, and final platform-ready exports tailored for destinations like YouTube or TikTok.

Does the agentic video workflow require a specific port configuration for Remotion Studio?▼

Yes, the agentic video workflow requires resolving the toolkit directory from LiteEVA setup, using Remotion Studio on port 7441, and routing local TTS fallback voiceover generation through port 5123.
