MEMO
MEMO is an AI model built to make crazy realistic talking head videos from just a pic and some audio. It is matching lip movements to speech keeping the same face through the whole clip and showing real-looking expressions that match the emotion in the voice.
Overview
MEMO came outta a solid team effort between folks from Skywork AI, Nanyang Tech in Singapore and NUS. Yep three big names all working together.
MEMO’s got two key parts that boost how it makes video:
Memory-Guided Temporal Module. This part helps it remember how the face looked before so it doesn’t drift or glitch. It uses info from more past frames than other models and that keeps things smooth and stable.
Emotion-Aware Audio Module. Instead of just looking at sound like a robot it actually picks up on the emotion in the voice and adjusts the face to match. It ditches the old cross-attention stuff and goes with something smarter called multi-modal attention. So yeah faces look way more expressive.
Tests show MEMO beats the older models in all the key areas.
Lip Sync. Mouth lines up perfectly with what’s being said.
Identity. The face stays the same all the way through even in long clips.
Emotions. You can feel what the person’s saying just by their face.
So yeah MEMO’s kinda perfect if you're making virtual avatars digital assistants or anything that needs face videos that look and feel real.

Some folks asked about directory control VRAM usage and how fast it runs. A few users shared test results using GPUs like 3090 and 4090—processing times ranged from minutes to hours depending on video length and hardware.
Some loved the tool for what it does especially in personal or indie projects. It’s solid for basic image-to-video lip sync with added subtle head and face motions. One commenter said it’s creepy another said it still looks like something out of a 2000s video game. But most agreed it’s a decent starting point if you mix it with other tools especially for ads social media or DIY games.
While a few users were skeptical about real-world use saying the output looks stiff or has weird z-axis movements others pointed out that for something free and open-source under Apache 2.0 it’s pretty impressive.
Bottom line MEMO-AVATAR isn’t perfect but it’s pretty great for open-source lip sync tools and worth checking out if you’re working on smaller creative stuff. [ Reddit ]
