ByteDance’s LatentSync: 6G Video Memory Enables AI Lip Sync

ByteDance open-sourced LatentSync 🚀, which can run with just 6GB of video memory, achieving “voice-controlled mouth” 👄, perfectly synchronizing the lip movements of video characters with the audio 🎶. Spatio-temporal stabilization technology makes the picture smoother 🎬, the one-click launch package is convenient and fast ✅, and it has a wide range of applications. Come and try it out! 🎉

Hey everyone! Have you been bombarded by all sorts of AI digital humans lately? Want to make one yourself? Don’t worry, today I’m recommending a super cool tool – LatentSync, open-sourced by ByteDance! It’s a treasure, and it’s said to run with just 6GB of video memory, a real blessing for the budget-conscious!

What is LatentSync?

Simply put, it’s a “lip-sync master”! Want the characters’ mouths in your videos to match the audio perfectly? This is the tool for you! It can automatically adjust the mouth shapes of the characters in the video based on the audio, as if it were tailor-made, and it’s incredibly precise! You’ll never have to worry about the characters’ mouths not matching the audio, making it feel like watching a “silent movie”!

How awesome is it?

• “Voice-Controlled Mouth”: It directly drives the mouth with sound, without those fancy intermediate steps, super easy!
• “Time Stabilizer”: It also has a unique skill called “time alignment,” which can keep the picture stable, without jumps or inconsistencies. Isn’t that amazing?!
• “All-in-One Toolbox”: It also comes with various tools to help you process videos and audio, such as adjusting frame rates, detecting faces, and removing flawed videos. It’s a one-stop shop to guarantee the video quality you produce is top-notch!

Techies, look here!

The technology behind this thing is not simple!

• End-to-End Latent Space Diffusion Model: Traditional lip-syncing technology is like a middleman making a profit, prone to problems. But LatentSync directly models the audio-visual relationship in the latent space, eliminating intermediate steps and achieving higher accuracy!
• Powered by Stable Diffusion: This is like installing a “super engine” for it, allowing it to generate more realistic and natural lip-sync effects, just like the real thing!
• Temporal Consistency Optimization: It also uses a technology called “TREPA” to ensure the video is coherent in time, without any screen jumps, making it more comfortable to watch!

Here’s the main point! One-click start package ready for you!

After hearing all this, are you already eager to try it out? Don’t worry, I’ve thoughtfully prepared a one-click start package for you! You no longer have to worry about configuring the environment or leaking privacy!
