Getting Started with LipDub AI

LipDub AI helps you translate, personalize, or replace dialogue in videos with high-quality, identity-preserving lip-sync. Start by choosing the project type that matches your goal and the number of faces shown in your footage. This guide introduces the four project types, the main areas of the platform, and the basic workflow from upload to finished video.

Choose the right project type

The most important first step is selecting the correct project type.

From Home, you can quickly start a Translation or Personalization project. To access all four project types, open Projects and select Create Project.

Project type

Choose this project when

Main inputs

Translation project

You want to translate a video featuring one visible face into one or more languages. LipDub generates translated speech and synchronizes it to the speaker’s lips.

A source video and your source and target languages

Personalization project

You want to create many customized versions of a video by changing details such as a name, company, or other variable.

A source video and a CSV containing recipient data

Dialogue Replacement project

You want to replace the dialogue in a video featuring one visible face, using uploaded audio or speech generated from written text.

A source video and either replacement audio or a script

Multi-speaker project

Multiple faces appear anywhere in the footage, or you need to control speaker training and assign separate audio to specific people. It can also share subject training data across multiple videos in the same project.

One or more source videos and separate audio for each speaker

Dialogue Replacement projects were previously called Single-speaker projects.

Important: Use a Multi-speaker project whenever more than one face appears at any point in the source footage— even when only one person speaks. It is the only project type that lets you choose which face detections are included in each person’s training data and assign audio to specific speakers.

In a Multi-speaker project, you only need to label and train the faces you intend to lip-sync.

Translate without lip-sync

When creating a Translation project, you can select Pure Dubbing to generate translated audio without changing the subject’s mouth movements. Pure Dubbing is a Translation project setting, not a separate project type.


The main navigation appears on the left side of the platform.

Understand the basic workflow

The exact steps differ by project type, but most LipDub projects follow the same general process:

  1. Create a project
    Choose the project type that matches your footage and intended result.
  2. Upload your source content
    Depending on the workflow, this may include a video, audio files, a written script, or a CSV.
  3. Process the footage
    LipDub analyzes the video and prepares it for the selected workflow. When training is required, LipDub uses visible footage of the subject speaking to learn their individual lip movement.
  4. Configure the new dialogue
    Translate the original speech, add personalization variables, upload replacement audio, or assign audio to individual speakers.
  5. Review your project
    Check the transcript, audio, speaker assignments, timing, and project-specific generation settings.
  6. Generate the video
    LipDub displays the project status while it is processing, training, or generating.
  7. Review and use the result
    Preview the completed video, download it, or use any sharing and export options available for that project type.

You can often return to the same project and generate additional languages, audio versions, personalized videos, or quality variations without starting over.


Before creating your first project

Keep these three rules in mind:

  • Choose the project type based on every face that appears in the footage—not only the person who speaks.
  • Use the cleanest and most consistent video and audio available. The inputs you provide directly affect the generated result.
  • Only upload voices and likenesses you have permission to use and clone.

For supported formats, recording recommendations, training-footage guidance, and upload requirements, see Prepare Videos, Audio, Transcripts, and CSV Files.


Continue with the appropriate guide

Once you have selected a project type, follow its complete workflow guide:

  • Translate and Lip-Sync a Video
  • Personalize Videos at Scale with a CSV
  • Replace Dialogue in a Single-Speaker Video
  • Create a Multi-Speaker LipDub
