I may have missed the obvious. I need to save a video in either M4V or MPEG 4 Video (probably the same thing, as described by another web site), and in 480 X 272 dimensions. I'm not quite sure how to do this in PE4. I know there are a number of presets, but do not see that one. I assume I choose the save to disk, but do not see how to select what I specifically need.
