I found a way of doing this differently, as I now found that tmix doesn't actually step frames, unlike skipblend. For history's sake, the way to get skipblend behaviour is to do something like "tmix=frames=100,framestep=150" for instance assuming you want to blend 100 frames, skip 50, and so on. It is *much* slower compared to skipblend by quite a large factor, as tmix does a lot of redundant computations, but it works.
