The need for speed

by leifs » Fri Aug 07, 2015 9:23 pm

I have a workflow that suits me for outdoor spheres, shot with a "normal" lens.
To shorten the time I've built me a computer with 2x Xeons and 128GB RAM, rather expensive and not fast enough !
It takes approximately 19 minutes to render this sphere (90 images).

So what is it doing for this time ? The image below shows that 13 out of 19 minutes is used for "Cutting".
What is this ? I think it is about antighost, but aren't shure.
Is there anything to do to shorten the "Cutting" time except uncheck antighost ? Render without antighost makes ugly result, so that's not an option.

Have a look here. also about cutting/blending results after changing from 16GB DELL PC to a 1x 2680Xeon with 128GB Ram (with no GPU):
viewtopic.php?f=16&t=23834&hilit=speedtest
(be patient and read all of them.... more than one know to tweak can be found there ;-)
if you can send me a download link I could download a 90 images set and give it a try on my Workstation...

PS: most of theis therad was about APG 3.x...

I've browsed through the thread, and noticed your focus on editing.
My post is more on rendering and especially on the timeconsuming anti-ghost rendering.
I rendered the same speedtest as you and the result is seen below. The only setting changed is simple vs anti-ghost.
The total time increases from 4:18min to 12:32min.
As the resulting pano from a simple rendering is useless, unless I use a lot of time editing the RMS as close to 1.0 as possible. If that is possible. I consider less time for editing and anti-ghost rendering as a better way.

I will play with the advanced settings later to check out if there is a viable compromise.

btw:
I've also got a Asus Z9PE-D16 :) (and 2x Xeon E5-2660)
