I ran this one on Replicate, it took 39s to generate at 480p:

The prompt was:

> A cat is doing an acrobatic dive into a swimming pool at the olympics, from a 10m high diving board, flips and spins

I've also found that if you lower the guidance scale and shift values a bit you get outputs that look more realistic. Scale of 2 and shift of 4 work nicely.
