What it does

InfiniteTalk is a novel sparse-frame video dubbing framework that generates unlimited-length talking videos with accurate lip synchronization, head movements, body posture, and facial expressions from audio input.

A novel sparse-frame video dubbing framework that generates unlimited-length talking videos with accurate lip synchronization, head movements, body posture, and facial expressions from audio input. Unlike traditional dubbing methods that focus solely on lips, InfiniteTalk synchronizes not only lip movements but also head movements, body posture, and facial expressions with audio, enabling infinite-length video generation with consistent identity preservation. InfiniteTalk is an audio-driven video generation tool for creating talking avatar videos. It uses audio to drive motion in videos, generating content from image to video with natural lip syncing and enhanced body motions while…from infinitetalk.org

  Infinity – Realistic AI characters that can speak2024 · ▲481

  Hey HN, this is Lina, Andrew, and Sidney from Infinity AI (https://infinity.ai/). We've trained our own foundation video model focused on people. As far as we know, this is the first time someone has trained a video diffusion transformer that’s driven by audio input. This is cool because it allows for expressive, realistic-looking characters that actually speak. Here’s a blog with a bunch of examples: https://toinfinityai.github.io/v2-launch-page/ If you want to try it out, you can either (1) go to https://studio.infinity.ai/try-inf2, or (2)…

  I’m excited to introduce Infinite Talk AI, a tool that creates realistic, unlimited-length AI talking videos. It transforms your audio into lifelike videos with synchronized lip movements, facial expressions, and body language. Inspiration Behind It Frustrated with the short video limits of other AI video tools, I created Infinite Talk AI to solve this problem. I wanted a platform that allows the creation of long, engaging content without any quality loss. Key Features: No Length Limits: Perfect for long-form videos like courses or virtual assistants. High-Quality Output: Lifelike lip-sync,…

  Term.everything – Run any GUI app in the terminal▲1,094

  I made a built-from scratch Wayland Compositor to display any GUI app* in the terminal! I think there is a lot of unexplored potential in custom Wayland compositors, a lot of really cool things you can embed existing applications into! So, I started with embedding apps into the terminal because that is the easiest input/output (output is just utf-8 and I use the great `chafa` library for that, and I just read from stdin for the input). If you have any other ideas for cool Wayland compositors, let me know. I purposedly wrote 80% the app in Typescript to appeal to the most developers and…

  I recreated Windows XP as my portfolio▲1,032

  Years ago I stumbled across a basic version of this concept and it stuck with me. I knew if I was ever going to take on such a project, it would need to be flawless, but without coding experience it was just another idea that would never happen. By the end of 2024, as AI coding tools exploded everywhere, I finally had a way to make it real. I started from zero knowledge and spent months collaborating with AI agents as a learning experience. Every pixel and every function went through me. The AI translated what I asked for into code, but every decision was human. I didn't use existing OS…
