So yesterday I took 120 ten second videos spaced apart by 20 seconds. Stacked the individual videos in AS3. Took the 120 TIFF's from AS3 into ImPPG to batch process and align. I'm having problems with the alignment part. Unless I use the curves tool and really make the images to be aligned highly altered it will not align properly. It produces only part of the picture and other weird stuff. I'm guiding by hand with a cross hair on a sunspot so the images are not that far off one another to begin with. Any ideas. Maybe a different work flow? I currently do AS3 - ImPPG - PIPP. Just starting off playing with animations. Thanks in advance for any help.
