Last frame has maximum iterations of 500'000, all pixels have iterations with more than 170'000 on the last frame.
Rendered with higher resolution than I use to do, in 4.5 days on a 32-bit dualcore laptop.

I used many colors on this one, and I think it turned out very well.

Last frame has maximum iterations of one million, all pixels have iterations with more than 500'000 on the last frame.
Rendered in a little more than one week on a 64-bit quadcore laptop.

I just regret that I used only 3 colors on this one...

though wait'll you see an antialiased 1280x960 still of that last minibrot rendered with a max-iter of 60 trillion. smiley

Fantastic. I'm very happy with that video. I couldn't have rendered that.

60 trillion, is that 6e13 (US) or is it 6e19 (EU)? Why, does it really make any difference to use such an extreme max-iter when a the last image in my movie only have a million?
Your image will not be e7 times bigger than mine (or e13)...?

I can imagine that your image would show the minibrot in sharp detail with max-iter 10 million or so smiley

6e13, and the detail isn't sharp enough at 10 million. 100 might be barely adequate. Fortunately, 60 trillion is actually fairly cheap to achieve with a rather remarkable optimization I've been testing, one which reduces the work for high-iteration areas near minibrots by a factor up to the minibrot's period ... which in this instance is nearly sixty thousand.
