Zuck (IG Post, FB Post) and some news outlets (ex1, ex2, ex3, ex4) highlighted some of the work our team did in video compute efficiency.

We reduced the cost to produce our basic video encodings by 94%. As a byproduct we were able to use that compute to improve advanced encoding watchtime coverage by 33%. These advanced encodings improve the user experience through higher visual quality and less stalls. If this sounds interesting to you, I wrote an engineering blog post with all the engineering details here
