SetEXIFData uses the excellent EXIFtool, which you should install first (I have included it in the download for your convenience). The nice toolbar icons come from Drew Wilson.
SetEXIFData uses EXIFtool to write most wanted EXIF data into an image or movie container (mov, m4v, mp4) - what EXIFtool supports.
The possibilities this application offers, are: renaming photos or videos, get EXIF dates/times from the file name of the photo or video, increment dates/times and sequence numbers, geotag photos and videos and store the found address, add camera info, add or replace keywords, modify the Finder's Date created or Date modified, etc..
