AI Video Generation Workflow – Open-source pipeline from topic to subtitle-ready MP4

Summary: AI Video Generation Workflow is an open-source modular pipeline that converts topics into final MP4 videos with synchronized subtitles. It automates script generation, slide preparation, TTS voiceover, subtitle timing based on audio, and FFmpeg rendering for consistent explainer video production.

What it does

It processes input topics through stages including script creation, slide setup, text-to-speech voiceover, subtitle alignment from actual audio durations, and final video rendering using FFmpeg.

Who it's for

Designed for creators producing batch explainer videos requiring stable, repeatable output and stage-by-stage reruns.

Why it matters

It addresses issues in text-to-video tools by ensuring consistent quality, accurate voice-subtitle sync, and efficient reruns without restarting the entire process.
