This is a closer look at Sora, OpenAI's amazing text to video AI.
We already know that it can create amazing videos from your text prompts with unprecedented
quality.
It is a huge leap in capabilities, but it can do so much more.
We know that it can take a still image and extend it forward into a video.
But, get this, it can also do the same, but backward.
And this one comes with a twist.
We prescribe how the video should end and it writes several possible ways of getting
there.
And they all feel completely natural to me.
That is awesome.
I love it.
Dear fellow scholars, this is Two Minute Papers with Dr. Karojona Ifeher.
And they really know how to make me happy because I am a light transport simulation researcher
by trade.
That is ray tracing if you will, so looking at the glassy reflections on the road and how
they change over time makes me really really happy.
Just look at that.
And not just the quality, but also the long term coherence as well.
I am used to looking at papers that can create videos that are at most 5 seconds long and
this particular one is a 20 second snippet.
That is amazing, but I read that it can go up to 60 seconds as well.
And look at those beautiful refractions and even little specs of dust and grease marks
on the glass are synthesized.
Wow!
Now, clearly there are lots of mistakes here, we can all see that, but this is also a remarkable
sign of understanding the world, and it can generate a full scene in one go.
We don't need to splice many results together, it can really give us a full scene without
any cuts.
Absolutely incredible, but it gets better.
This result puts even the 60 second to shame. Let's look at this together.
Hmm, and if we do it for a while, wait, so when does this end exactly?
Well, did you notice? Yes, you are seeing correctly, it never ends.
It can also create infinitely looping videos as well. And it can also perform limited physics simulations.
We are going to get back to that in a moment that is not only beautiful.
I mean, just look at that.
But this has a profoundly important story behind it.
Now, it can also create still images.
Yes, I hear you asking, Karoi, why is that interesting?
We just saw videos.
Those are way more difficult.
Well, but these are 2048 by 2048 images.
Those are huge with tons of detail.
And remember, Dolly 3 appeared approximately 6 months ago.
That technique is a specialist in creating high quality images and this one even beats Dolly
3, the king in its own game.
And it does all this as an almost completely unintentional side effect.
Wow.
And large language models think in tokens batches of letters.
But Sora is for video and it does not think in tokens at least not in the way the language
