If you have Mathematica, you could use its import/export capabilities to read in png files and export them into various video formats. Mathematica is an expensive overkill if the only thing you want to do is assemble a video, but if you do have access to it, it is a straightforward thing to do: 

SetDirectory at NotebookDirectory[];
fileList = Table[(ToString at i) <> ".png", {i, 1, 10}];
myFrames = Import /@ fileList;
Export["myMovie.mov", myFrames, "VideoEncoding" -> "MPEG-4 Video”]

These commands read 10 files with the names i.png (i=1,…,10) and export them in a movie that plays in quicktime on mavericks.
