Can I swap a single word or small portion of my video?

Last updated: February 2, 2026

Context

You may need to replace just one word or a small portion of an existing video without having to recreate the entire content. This could be for correcting a mistake, updating information, making minor adjustments to your video content, or for marketing purposes.

Answer

Yes, word-level swaps and fine grain control of what gets lipsynced is supported in Sync AI. You can achieve this by following these steps:

  1. Create a new project or open an existing project:

    Generate the replacement audio for that specific word or phrase using either Text-to-Speech (TTS) with a voice clone or by bringing in an already prepared audio file.
