Hi Bo, is very slow when you charge a very large nuembers of images and press STICH, 150 or more photos.
I compare 3 software with the same photos…
Autopano Giga, PTGui Pro, Gigapan Stich
and the result is 40 minutes, 230 minutes and 45 minutes in the same order.

Hmmm…230 /40 = 5.75. That’s much less than “20 times”.

I have compared the results w/ a smaller number of images and PTGui Pro was faster than Stitch.

One issue is that PTGui is available in 64-bit version, so it accesses more memory and runs faster than an equivalent 32-bit program. Next, Stitch appears to do some of the processing on the GiagPan servers [rather than my local box]. This means that if I have a slow PC and a fast internet connection, I can get rapid results. But, if my internet connection is slow, then it will control the overall process timings.

I have an 8-core box, running at 3.4 GHz, w/ 16 GB of RAM and a sorta fast internet hookup [5.25/1.62 Mbps on Speedtest.net], to get you calibrated. I just tried the same [small…16 images] job on PTGui Pro and Stitch. Stitch took 0:36 and PTGui took 0:47. BUT, after this 36 seconds, Stitch didn’t have anything completed…only a 32 kb .gigapan file! In contrast, PTGui Pro had completed a 92,370 kb .jpg file.

I don’t know what is in that .gigapan file, but it can’t be much…it appears to be only a small preview [the PTGui Pro file was 2887 times bigger)! When I told Stitch to upload the panorama, it took a whopping 7:30. It doesn’t take 7 1/2 minutes to upload 32 kb, so something quite different is going on?

It’s difficult to make a generalization like this. PTGui Pro has many more capabilities than Stitch. One program operates locally and the other operates remotely. Their results are not comparable [the PTGui image was 23,716 × 5,037 px, whereas the Stitch image was 23,576 × 4496 px.

I don’t know how to render a Stitch image as a JPEG and get it on my local box [or even if it’s possible…a quick search indicated that only TIFF and DNG outputs were possible?], so trying to get comparable processes in order to time the entire thing may be difficult.
