I found that jpgs reduced the file swapping load. Also, on a box with two HD's you can offload file swapping (vram) to one drive and this leaves the silicon free for processing load.
Indeed, you want to optimize with the smaller files. One tip is to just change the file names/paths in the pto when it's time to stitch with the big images. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Bart.van.Andel Sent: Friday, December 19, 2008 11:00 AM To: hugin and other free panoramic software Subject: [hugin-ptx] Re: any way of replacing low-resolution images with higher-resolution originals? I think what breic means is downsizing in resolution, not merely jpeg file compression. Although jpeg images will load faster than tiffs due to their file size, they use the same amount of memory when loaded and will slow down CP finding, CP manipulation and preview displaying. Since Hugin and the tools used by Hugin use pixel coordinates for the CPs, reoptimizing will fail after replacing small images with bigger ones, because the pixel locations will be different. Just open a .pto file in a text editor to find the coordinates. However, when you have already optimized with the smaller images, you can then close the project, replace the image files with the bigger files and load the project back into Hugin. Don't reoptimize, but go to the Stitcher tab immediately and stitch the image. I just tested it on a small 2 image panorama. It works because after optimizing, the .pto file contains the necessary information about roll, pitch, yaw and other warping values, next to the (at this point unnecessary) CP information.
