OmniHuman-1: Human Animation Models

These look.. great, by and large. Hands are super natural, coherency is really high. Showing off piano chord blocking is a huge flex.<p>I’d like to play with this! No code, but bytedance often releases models, so I’m hopeful. It’s significantly better than vasa, and looks likely to be an iteration of that architecture.

Many of these have tells, but this one fully crossed the uncanny valley for me. <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=1NU8NzvAxEg&amp;t=16s" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=1NU8NzvAxEg&amp;t=16s</a><p>Good to know that I need to now assume performances are AI generated even if it&#x27;s not obvious that they are!

What are the tells in most of these videos? I can&#x27;t point at any in many of them. Hands, teeth, lip sync, body and should movement all look correct. Specially the TED talk like presentation examples near bottom.

This looks better than EMO (also closed source by Alibaba group <a href="https:&#x2F;&#x2F;humanaigc.github.io&#x2F;emote-portrait-alive&#x2F;" rel="nofollow">https:&#x2F;&#x2F;humanaigc.github.io&#x2F;emote-portrait-alive&#x2F;</a>). See the rap example on their page. They apparently have EMO2 now which doesn&#x27;t look as believable to me.<p>EMO covers head + shoulders while this OmniHuman-1 is covering full body and its looking even better. I would have easily mistaken these for real (specially while doom scrolling) if I was not looking for AI glitches.<p>UPDATE: Googling animate bytedance site:github.io returns many in the same domain (all proprietry).

This is very good attempt with people playing musical instruments.<p>But, there are some subtle timing tells, that this is AI generated. Take a look at the singer playing the piano. Timing of the hands with the singer is slightly off. The same goes with the singer and the guitar. I&#x27;m not a guitar player or piano player, but I do play a lot of different musical instruments at a high level, and the timing looks off, slightly ahead or behind the actual piece of audio of the piece of music.

&gt; Ethics Concerns<p>&gt; The images and audios used in these demos are from public sources or generated by models, and are solely used to demonstrate the capabilities of this research work. If there are any concerns, please contact us (jianwen.alan@gmail.com) and we will delete it in time.<p>Ethical concerns with this technology have nothing to do with videos on a demo page, and everything to do with what can be generated later.<p>I don’t know if they have a profound lack of understanding of the ethical implications or are purposefully trying to pretend, but neither is good.

I run youtube channels with almost 2 billion views and this actually concerns me. I would love to try this in my productions!!

NVIDIA Demo of Audio2Face is such a joke, compared to this one.

this could be used as an incredible low bitrate codec for some streaming use cases. (video conferencing&#x2F;podcasts on &lt;3G for ex, just use some keyframes + the audio).

...I feel slapped by progress. Rarely does such an impressive demo leave me feeling less inspired and hopeful about the future.

It looks funny.

Modern operating systems should include by default a very simple private&#x2F;public key system to sign arbitrary files. I think it should not be very complicated? We badly need this in the age of AI.
