How much memory should I allocate to Zerene Stacker?
The memory requirement is determined by image size as measured by pixel count. The ideal setting is roughly 100 MB for each 1 megapixel, so 12 megapixel images need 1200 MB, 24 megapixel images need 2400 MB, and so on. Somewhat smaller settings can be used, down to a minimum of roughly 75 MB for each 1 megapixel, but this may make stacking run a little slower. Note that the memory requirement depends on pixel count and not on input file size or number of frames in the stack. There is no significant difference in memory requirement between processing JPEG and TIFF images, and the memory requirement does not increase with deeper stacks. In most cases it is counterproductive to allocate much more memory than described above, because this will just cause more contention with other processes in your computer. The current behavior of Options > Preferences > Memory Usage > “Set Automatically” is not ideal in this regard, since on large 64-bit systems it often allocates more memory than is nee
