Comment 1 for bug 605398

Movies are now generated such that instead of using the requested start and end dates, the nearest image at/inside each date is used instead. This eliminates problems caused by having gaps at either end of the request range which is currently the more problematic scenario. Future iterations may be improved by doing things like requesting all images with the request region (for regions which are not too large) and sub-sampling, or recursively dividing up time range and returning counts for each region with > 0 records to get a better picture of where gaps exist in the request range, and then only select frames from within those regions.
