LipDub AI Deep Dive: 5 Min to Understand this Viral Lip Sync AI

What is LipDub AI: Know the Hollywood-grade lip sync platform

LipDub AI is a cutting-edge video lip sync technology created by MARZ, the renowned visual effects studio behind hits like WandaVision and The Umbrella Academy. LipDup was branded as a Hollywood-caliber tool, and it delivers ultra-precise, high-resolution lip syncing. It's specifically designed for studios and enterprise-level creators who need seamless audio-to-visual alignment for dubbed scenes and character animations. However, this sophistication comes at a cost. LipDub AI's workflow is highly technical, and its interface and infrastructure cater to seasoned post-production professionals, making it less suitable for most users.

LipDub AI workflow breakdown: Two methods analyzed

LipDub AI offers two distinct project types, each tailored for different use cases, but both come with their own technical requirements and workflow limitations. Let's break down how each one functions, what you need to prepare, and what challenges you might encounter during production. This way, you can better determine which workflow fits your needs or if a simpler alternative might be more efficient.

Method 1: LipDub video AI single actor workflow

STEP 1
1. Sign up

Visit the LipDub AI website by searching for it on your browser. When you are on the homepage, click on "Log in" to log into your account. If you do not have an account, click on "Sign up" to create one. After creating an account, you'll be asked some questions before you can start using LipDub AI.

STEP 2
1. Upload your single actor video

When you are in, click on "Create a new project" and then click on "Single actor video" to upload your video. Before uploading your video, make sure the video you are uploading is a short video clip, ideally between 30 to 60 seconds, featuring a single actor. Also, ensure the video has clear visibility of the actor’s mouth movements, steady lighting conditions, and minimal background noise or distractions. This initial clip serves as the foundation for LipDub’s model training process.

STEP 3
1. Upload audio and commence model training

Next, click on "Choose audio" to submit the audio file you want the actor to lip-sync to. This audio can be a speech, narration, or any vocal content. Make sure it’s high quality and matches the tone and pace you want the actor to portray. After uploading your audio, click on "Generate" to start the model training. LipDub AI will now train a custom model based on the uploaded video and audio. This phase typically takes 1 to 4 hours, as the system studies the actor’s facial features, lip dynamics, and expressions. The goal is to accurately replicate the actor’s speaking style and ensure natural-looking lip-sync results.

STEP 4
1. Download

Once your LipDubbed video is ready, click on the "Play" icon to view it and then click on "Download result" to save it to your computer. At the top of the canvas, you will see where you can access your original uploaded video, click on it to view your original video and then compare it to the LipDubbed video to see the difference.

Method 2: LipDub video AI multi-actor workflow

STEP 1
1. Upload your multi-actor video

After logging in, click on "Create a new project" and then click on "Multi-actor videos" on the next screen to upload your video. In your video, each actor should have a clearly visible face and mouth, with stable lighting and minimal background distractions to ensure accurate facial tracking and lip synchronization.

STEP 2
1. Upload audio

After your video has been uploaded, click on "Choose audio" to upload your audio. You should note that the audio must match the timing and expression of each actor's intended dialogue. Then, click on "Proceed to LipDubbing" to continue.

STEP 3
1. Train the model

After you have clicked on "Proceed to LipDubbing," you should also click on "Generate" to start the model training. LipDub will begin training a separate model for each actor to adapt to their unique facial patterns and speech. This may take 1–4 hours per actor. Once all speaker models are trained, the system will sync the voices and render the final multi-actor video with realistic and cohesive lip movements.

STEP 4
1. Download

Once your lip-dubbed video is ready, click on the "Play" icon to view it and then click on "Original" at the top of the canvas to view the original video. If everything is good, click on "Download result" to save it to your computer.

FAQs

1
1. Why does LipDubs take so long to process videos?

LipDub takes a long time to process videos because for each actor in a video, the platform requires 1 to 4 hours of model training before lip sync generation can even begin. This training is important for the system to understand and replicate the subject's facial movements accurately, but it also makes LipDub AI highly inefficient for creators working on tight deadlines or rapid iterations. When you are using Dreamina, it eliminates the need for training. Based on trained and updated models, Dreamina generates lip-synced videos within minutes, allowing creators to move faster and produce content. Get started instantly with Dreamina now, no setup, no delay, just results.
