Can I vibe code Synthesia?
AI avatar videos from a script — training and marketing at scale.
Photorealistic talking avatars with accurate lip-sync are frontier model territory: licensed actor likenesses, voice cloning, and rendering infrastructure that took specialist teams years. A vibe-coded version means calling someone's avatar API — renting the same capability with extra steps. The honest question is whether you need an avatar at all: a screen recording with your real face, or a voiceover over slides, is buildable today and often lands better.
Skip the avatar — build a script-to-video pipeline I own. Input: a markdown script split into sections, each with slide text or an uploaded image. Pipeline: generate voiceover per section with a TTS API (voice configurable), render slides to images (satori or headless browser), then stitch slides + audio into an MP4 with ffmpeg, with simple crossfades and a progress bar during render. Output gallery with download links. Make section timing follow the audio length automatically. Next.js + a server ffmpeg route, files in object storage.
Realistically: a script-to-video tool that pairs an AI voiceover (TTS API) with slides or B-roll — no avatar, but a real automated video pipeline you own.
- The avatars — photorealistic presenters in 140+ languages
- Enterprise features: brand kits, collaboration, SCORM export
- Consistent lip-sync quality across languages
- Legal clarity of licensed actor likenesses
Companies producing training in 20 languages replace film crews and reshoots with a script edit — the ROI math is real at enterprise scale.
