<p>That the calibration got the simulation so close to reality was quite impressive.</p>

<p>We are using MuJoCo to train a G1 humanoid robot right now. The best thing is that we do not need to fight with NVIDIA software and that it runs on macOS.<p>PS: I just finished a first draft for agentic skills around working with MuJoCo in Python. Feel free to check them out here:

<p>I have compiled some best effort motion canvas skills. They also contain agent instructions for how to capture and export screenshots and the final video, so, in theory, the agent can create a video fully autonomously.
Here is a very boring demo: <a href="https://www.youtube.com/watch?v=e8eHLTMWLlo" rel="nofollow">https://www.youtube.com/watch?v=e8eHLTMWLlo</a></p>

<p>If you have worked with MotionCanvas or wanted to give 2D canvas animations it a try, you might notice that the website is currently not reachable and that the repo has not received any updates in over a year, suggesting that the project is not actively maintained at the moment.<p>However, you will also find that the community is still active and that, for example, Canvas Commons is an active fork of the original repo: <a href="https://github.com/canvas-commons/canvas-commons" rel="nofollow">https://github.com/canvas-commons/canvas-commons</a><p>Docs for Canvas Commons: <a href="https://canvascommons.io/" rel="nofollow">https://canvascommons.io/</a>
Furthermore, the old docs for Motion Canvas can be found here: <a href="https://archive.canvascommons.io/" rel="nofollow">https://archive.canvascommons.io/</a><p>Cheers!

<p>Hello Hacker News! I've been lurking on hacker news, and it is amazing what people have built!
I'm Patrick and I built a 2D video generation tool at VideoZero.ai that can produce crisp technical videos (text, formulas, graphs) by using code instead of generating raw pixels.<p>After my PhD, I really wanted to do something more creative, and I started creating educational videos about computer science. I felt there was a huge need for engaging, short educational videos to counter all the let's say, "less brain-activating” short videos on social media. I came across Motion Canvas and its use of generator to define animations really resonated with the way I like to code. However, I quickly realized that making high quality videos takes forever! And, unfortunately, existing AI tools cannot generate technical videos that well, they can’t even handle simple text! But then I thought, wait a minute, creating videos with Motion Canvas? This is just code? I turned around and looked at my AI buddy Claude and I told him “you can do it”!<p>I spent the following months working on that vision of enabling LLMs to generate 2D videos that don't break after just 10 seconds. The result is now called VideoZero and you can try it for free at videozero.ai (paid from my personal credit card). For one, here is the result of visualizing Conway's Game of Life: <a href="https://videozero.ai/view/?id=040c6732-38f3-4990-baff-73d03d" rel="nofollow">https://videozero.ai/view/?id=040c6732-38f3-4990-baff-73d03d</a>...<p>Sometimes the videos are quite good, on other occasions, let's say they need a bit of refinement.<p>Would love to hear what you think and what you would like to visualize.<p>Cheers and have a good weekend!

<p>There are a lot of old and new mobile applications doing this.

<p>I work as a freelancer, but I have been wanting to start something of my own. A couple of months ago, I started working on VideoZero.ai with the vision of generating videos that feature text, formulas, and graph elements without breaking after 10 seconds or weird artifacts. Instead of generating raw pixel values, we leverage Motion Canvas to create the video elements. Some results are quite cool, but some videos are quite crappy. We have a whole list of animations to explore here: <a href="https://videozero.ai/gallery" rel="nofollow">https://videozero.ai/gallery</a></p>

<p>I really like the interactive elements and animations.<p>Small nit on the wording: "This continuous cycle enables self-sustaining, self-propagating electromagnetic waves"<p>The term “self-propagating” makes it sound like the fields are somehow pushing each other forward, but really they’re just coupled solutions of Maxwell’s equations.</p>
