ParaView does adjust image sizes when saving avis, for example. Not sure if its needed when saving out images.

So, there is no reason to add the option in ParaView to create flipbooks mod 4, correct?

ffmeg is your friend on linux. It needs a little figuring things out, but both resizing images and then converting them to videos is possible.

A common workflow for ParaView is to write out animations as a flipbook – i.e., write out movies as a series of .jpgs or .pngs.  If a person wants to post process these pictures into .avi’s or .mov’s, what tools do people use?  Further, can these tools deal with the case that .avi’s need X and Ys that are mod 4 == 0, where the raw .png’s can be any X and Y?  Does ParaView need the optional ability to force .png’s or .jpg’s to be written out mod 4 == 0?
