I Fixed It!
This video was made following a tutorial by the people on Houdini (http://www.sidefx.com/index.php?option=com_content&task=view&id=2157&Itemid=132). This tutorial doesn’t show you how to render it. Unfortunately, the foam could not be rendered, so you’re just seeing the plain ol’ water render. Still pretty cool though!
Finally, my videos will be in the correct dimensions, since before, I had forgotten to change the Blender camera when putting all the frames together to the right resolution. Ooops. Now I’m going to have to re-do them. Luckily I still have the frames!
