ImageJ is a free, powerful image analysis program from the US National Institutes of Health (http://rsbweb.nih.gov/ij/download.html ). VDA video files that are being viewed can be loaded from FastLook into ImageJ automatically from the Menu. Alternatively, VDA files can be loaded directly into ImageJ from its Menu (see picture below).
The following two files, which are located in the ImageJ subdirectory of jClamp or FastLook, have to be placed in the ImageJ directory, C:\Program Files\ImageJ\plugins\Input-Output, in order to work with VDA files.
Also, in the macro section of ImageJ you can load the scale for the image, if already set in FastLook, by running "fl_set_scale".
