If you are on a Mac, try Graphic Converter - you can batch all the still frames into a .mov. You can also add a sound file. However, it is not a video editor, just a converter. I ended up taking all our 3dsMax tifs and pngs, into Graphic Converter to get movies (keep quality high and compression low). Then into iMovie to get the size down to 50 MB - which was a lot of trial and error.
Constrain bitrate, (kbyte/sec) not the quality slider.
