Creating "Smoothies" requires 3 steps: 1) preparation of input images. - selecting the images with the same size, wavelength, exposures, etc. - eliminating junk or bad images (this affects the final quality). - make sure if they are co-aligned. - using filename list (for OK images) is a good idea. 2) process interpolated images (sxt_smoothy_9807_nousm.pro). - edit parameters: cadence, number of images to conposite, w/wo unsharp masking, color table, etc. - this will need try-and-error. 3) create movies from the output images. - Javascript, QT, Mpeg, as you like. Good Luck!
