Hey,
 I m working in a windows pc on molecular imaging and we need to measure the fluorescence of organs in diferents intervals, not in a specific time.
 I just cannot find any software that is able to take an video stream ( working in set intervals ) and transforme it in a stack .tif. Do you guys have some sugestion? Do you guys think that if i convert my .vob file ( dvd video ) in quick time and then into a stack will lose some quality?
 I need to point out that this video has about 1 hour in high quality and I intent to take some intervals between 5 and 15 minutes to run my analysis. I've tried to use virtualdub but, to open the video files in this software, first need to convert in .avi using the software "convert vob to avi " and I'm afraid of losing quality. Moreover, I cannot find the function of taking several shots in a row of intervals of my interest.
  Thank you and sorry being repetitive..
