   Indeed, it's really great. It does the smartest thing of all: it creates an HTML page and uses raw JS timed animations to make it work. Then it records it with ffmpeg and saves the output as the final video.

   About 6 months ago I spent 12 hours creating a video for our Edge.js [1] announcement that, in the end... people were not very inspired by (to say the least). See the video here [2].

   Then, about a month ago, I spent 6 hours creating a video for our Wasmer SDK announcement. It was better, but still didn't go as viral as I wanted [3]. I always thought we would need a big budget to do them.

   But then, yesterday I tried Opus 5.5... and man, I'm impressed. The video was one-shotted with this prompt:

       Make a modern slick and punchy video for this announcement:

   This is what Claude Opus 5.5 one-shotted (tl;dr: we went viral): <a href="https:&#x2F;&#x2F;x.com&#x2F;wasmerio&#x2F;status&#x2F;2102849543260029379" rel="nofollow">https:&#x2F;&#x2F;x.com&#x2F;wasmerio&#x2F;status&#x2F;2102849543260029379

      &gt;&gt;&gt; records it with ffmpeg

      Exactly how? What does ffmpeg record?

         I believe it captures each of the frames as png and then ffmpeg puts them together as a video. Although someone from Anthropic may be able to explain this better
