Storing 30*80 matrices per second would result in 30*80*16*4 bytes = 150 kB, so at 6-7 seconds, a megabyte of
animation data is needed. If we can get away with 36 bones, just 6 fps, and storing 12 values per animation matrix,
this figure decreases to 6*36*12*4 bytes = 10 kB. Obviously, if the animations do not look good with less data, you need
to increase the fps. In most projects, we have either saved enough pre-calculated animation matrices to look good
enough, or we stored only the bare minimum and used blending between the animation matrices at the cost of a few
CPU cycles to save a lot of memory.
