Hello this is Kate White, I am also visualizing a series of vector fields, but I don't animate in opendx. Once I have the sequencer set up I go to "save image", save in the "miff" format, and save continuously. Then I run the sequencer, then unclick continuous saving and close the dialog box. The miff format is easy to convert to an mpeg movie using image magick. (http://www.imagemagick.org for download)
