Talking Head Production

Talking Head Production

When to Use

Use this skill as needed to perform the specified automation task.

Create talking head videos with AI avatars and lipsync via inference.sh CLI.

Quick Start

curl -fsSL https://cli.inference.sh | sh && infsh login

# Generate dialogue audio
infsh app run falai/dia-tts --input '{
  "prompt": "[S1] Welcome to our product tour. Today I will show you three features that will save you hours every week."
}'

# Create talking head video with OmniHuman
infsh app run bytedance/omnihuman-1-5 --input '{
  "image": "path/to/portrait.png",
  "audio": "path/to/dialogue.mp3"
}'

Portrait Requirements

The source portrait image is critical. Poor portraits = poor video output.

Must Have

Background

# Generate a professional portrait background
infsh app run falai/flux-dev-lora --input '{
  "prompt": "professional headshot photograph of a friendly business person, soft studio lighting, clean grey background, head and shoulders, direct eye contact, neutral pleasant expression, high quality portrait photography"
}'

# Or remove background from existing portrait
infsh app run <bg-removal-app> --input '{
  "image": "path/to/portrait-with-background.png"
}'

Audio Quality

Audio quality directly impacts lipsync accuracy. Clean audio = accurate lip movement.

Requirements

Generating Audio

# Simple narration
infsh app run falai/dia-tts --input '{
  "prompt": "[S1] Hi there! I am excited to share something with you today. We have been working on a feature that our users have been requesting for months... and it is finally here."
}'

# With emotion and pacing
infsh app run falai/dia-tts --input '{
  "prompt": "[S1] You know what is frustrating? Spending hours on tasks that should take minutes. (sighs) We have all been there. But what if I told you... there is a better way?"
}'

Model Selection

Production Workflows

Basic: Portrait + Audio -> Video

# 1. Generate or prepare audio
infsh app run falai/dia-tts --input '{
  "prompt": "[S1] Your narration script here."
}'

# 2. Generate talking head
infsh app run bytedance/omnihuman-1-5 --input '{
  "image": "portrait.png",
  "audio": "narration.mp3"
}'

With Captions

# 1-2. Same as above

# 3. Add captions to the talking head video
infsh app run infsh/caption-videos --input '{
  "video": "talking-head.mp4",
  "caption_file": "captions.srt"
}'

Long-Form (Stitched Clips)

For content longer than 30 seconds, split into segments:

# Generate audio segments
infsh app run falai/dia-tts --input '{"prompt": "[S1] Segment one script."}' --no-wait
infsh app run falai/dia-tts --input '{"prompt": "[S1] Segment two script."}' --no-wait
infsh app run falai/dia-tts --input '{"prompt": "[S1] Segment three script."}' --no-wait

# Generate talking head for each segment (same portrait for consistency)
infsh app run bytedance/omnihuman-1-5 --input '{"image": "portrait.png", "audio": "segment1.mp3"}' --no-wait
infsh app run bytedance/omnihuman-1-5 --input '{"image": "portrait.png", "audio": "segment2.mp3"}' --no-wait
infsh app run bytedance/omnihuman-1-5 --input '{"image": "portrait.png", "audio": "segment3.mp3"}' --no-wait

# Merge all segments
infsh app run infsh/media-merger --input '{
  "media": ["segment1.mp4", "segment2.mp4", "segment3.mp4"]
}'

Multi-Character Conversation

OmniHuman 1.5 supports up to 2 characters:

# 1. Generate dialogue with two speakers
infsh app run falai/dia-tts --input '{
  "prompt": "[S1] So tell me about the new feature. [S2] Sure! We built a dashboard that shows real-time analytics. [S1] That sounds great. How long did it take? [S2] About two weeks from concept to launch."
}'

# 2. Create video with two characters
infsh app run bytedance/omnihuman-1-5 --input '{
  "image": "two-person-portrait.png",
  "audio": "dialogue.mp3"
}'
