Talking Head & Avatar Video Generation

Portrait + TTS = lip-synced avatar video. OmniHuman 1.5 makes it production-ready at $0.14/sec.

Real-world application: Talking head / avatar generation integration (OmniHuman + TTS) is a niche but growing skill — companies building training content and spokesperson videos test for this.

What you will learn

Integrate ByteDance OmniHuman 1.5 for realistic talking-head videos from a single portrait
Build a pipeline: text → TTS audio → OmniHuman → lip-synced video output
Understand use cases: training content, music video performance, spokesperson videos
Evaluate quality considerations: lighting, portrait quality, motion naturalness

Objective

Create motion evidence that can be reviewed frame by frame, not only as a successful API response. In the paired studio lab, build a complete talking head pipeline: (1) generate or provide a portrait image, (2) generate TTS audio from text using ElevenLabs, (3) generate a lip-synced video using OmniHuman via fal.ai. Track total cost and generation time.

The Problem

A company needs to produce 100 training videos with a consistent spokesperson. Hiring a human actor for each video costs $500+ per video and takes days to schedule. They need a scalable solution: provide a portrait photo and a script, get a lip-synced video of the person speaking.

This is talking head generation — combining a portrait image with TTS audio to create a video of the person speaking with lip-synced mouth movements. ByteDance's OmniHuman 1.5 makes this production-ready.
