Indeed, if all you need is frames with changing content...

In my setup(s), life is approx 3x fast than mandelbrot, and testsrc2 is
even 25x faster.

(mptestsrc only delivers 512x512, AFAICT, so it would need to be
rescaled again?)

$ ffmpeg -filters | grep '|->V'
for more sources. I think the documentation even has a section of its
own, but I haven't checked whether all are even mentioned.
