What it does

Video Podcast Maker is an agent-orchestrated pipeline that researches a topic, writes a script, generates narration through multiple TTS backends, and renders a 4K video in Remotion. It targets five platforms — Bilibili, YouTube, Xiaohongshu, Douyin, and WeChat Channels — with per-platform formatting, thumbnails, and call-to-action presets. The human’s job is to describe the topic and then mercilessly edit the resulting podcast.txt; the agent handles the rest.

The interesting bit

The README contains an unusually honest, all-caps warning to humans (not the AI) that the script is the single source of truth for every downstream step — “A weak script renders into 4K garbage.” It is refreshing documentation: it knows the bottleneck is prose quality, not rendering speed.

Key highlights

• Seven TTS backends supported, from free Edge TTS to ElevenLabs and CosyVoice, with bilingual Chinese/English mixing and per-project phoneme correction.
• Remotion-native 4K subtitles rendered in React/CSS; legacy FFmpeg burn-in still available.
• Platform-specific output rules baked in: Bilibili chapter timestamps, Xiaohongshu 3:4 thumbnails, Douyin 9:16 vertical-only shorts.
• Reusable React component library (ComparisonCard, DataBar, FlowChart, LottieAnimation, etc.) for composing section layouts.
• Manual style_profiles in user_prefs.json carry palette and typography across videos; automatic preference learning is on the roadmap.

Caveats

• Requires a separate Remotion project as foundation; this repo is the workflow skill, not a standalone app.
• macOS and Linux only; Windows compatibility is not mentioned.
• Heavy API key sprawl: Azure, Volcengine, Aliyun, ElevenLabs, Google Cloud, OpenAI, Gemini — most are optional, but the matrix is wide.
• The authors note the project is “still under active development and may not be fully mature yet.”

Verdict

Worth a look if you are already publishing to Chinese and Western video platforms and want to automate the mechanical parts — rendering, subtitles, platform formatting — while keeping creative control over the script. Skip it if you expect a one-click SaaS; this is a local toolchain that expects you to curate API keys and edit text.
