AI Video Generator FAQs

Product Basics
  • What is LipSynthesis?
    LipSynthesis is an AI-powered video platform featuring realistic stock and custom avatars. Generate lip-synced, multilingual videos for ads, reviews, training, support, and more—no camera, studio, or actor required.
  • How is LipSynthesis different from other AI avatar platforms?

    Unlike platforms that use computer-generated (CGI) avatars, LipSynthesis features real people filmed on location. Our avatars are actual humans—teachers, professionals, everyday people—digitized for AI video creation. This means:

    • No uncanny valley effect — Real faces, real expressions, real trust
    • Natural backgrounds — Filmed in offices, homes, and outdoor settings (not green screens)
    • Authentic connection — Your audience sees real humans, not obvious AI characters

    The result? Videos that feel genuine and build trust—perfect for customer-facing content where authenticity matters.

  • How does LipSynthesis work?

    LipSynthesis combines real human footage with AI technology:

    1. Choose an avatar — Select from 300+ real humans filmed on location, or create your own custom avatar
    2. Select a voice — Use our built-in voices, upload your own audio, or connect your ElevenLabs account
    3. Write your script — Type what you want your avatar to say
    4. Generate — Our AI lip-syncs the avatar to your script
  • Do AI avatar videos look realistic?

    Yes. LipSynthesis avatars are real people filmed on location, not computer-generated CGI—so they look and feel authentic by default.

    Our advanced lip-sync technology ensures natural mouth movements, and because the avatars are filmed in real environments (offices, homes, outdoor settings), the videos feel genuine and trustworthy.

    Many users report that viewers can't tell they're AI-generated—especially with custom voices and natural pacing.

  • Are your avatars ethically sourced?

    Yes. Every stock avatar on LipSynthesis is a real person who consented to be filmed and digitized for AI video generation. We believe in ethical AI—using real humans who agreed to participate, not creating fake people or deepfakes.

    For custom avatars, you own the rights to your own likeness and control how it's used.

Avatars
  • What's the difference between stock and custom avatars?

    Stock avatars are ready-to-use avatars filmed from real people representing diverse demographics, professions, and settings. Choose from teachers, professionals, everyday humans filmed in offices, homes, and natural environments.

    Custom avatars are created from a 40-60 second video of yourself (or your team). We digitize your face, voice, and expressions so you can generate unlimited videos with YOUR likeness—without filming every time.

    Both types are real people (not CGI), ensuring authentic, trustworthy videos.

  • How do I create a custom avatar?

    Creating your custom AI avatar is simple:

    • Record a 40-60 second video of yourself speaking naturally to the camera
    • Upload it to LipSynthesis
    • Wait for processing (we'll notify you when it's ready)
