System Design

Deep Agent Workflow

An iterative thinking and research cycle that spawns specialized sub-agents to conduct deep investigations.

Continuous Iterative Cycle: The Deep Agent uses its think tool to analyze and reflect on the problem, writes research todos, spawns specialized sub-agents with internet search capabilities, collects their findings, updates the todo list based on results, and continues cycling until research is complete.

Complete Process

Project Pipeline

Six automated stages transform any input into professional educational motion graphics videos.

Deep Research & Planning

Deep Agent analyzes input complexity and spawns sub-agents for in-depth research. Generates structured plan.json with narration scripts, visual prompts, and video specifications.

Audio Generation

ElevenLabs API generates high-quality voiceover narration. Audio duration is captured and plan.json is updated with precise timing.

Prompt Refinement

Video Prompt Refiner Agent generates detailed visual specifications including positioning, scale, lighting, and cinematography for Hera API.

Motion Graphics

Prompts are submitted to Hera Motion Graphics API. Batch jobs generate each clip segment which are monitored and downloaded.

Synchronization

Video clips are synchronized with corresponding narration audio using precise duration metadata for perfect timing alignment.

Final Assembly

FFmpeg stitches all clips together. Transitions are smoothed, audio is normalized, and the final video is rendered.
