Sub Pixel shaky animation

Hi All

Is there a way to force movieclips to whole pixels? When doing timeline animations I am constantly having to adjust my x and y coordinates to whole numbers manually. If they are not whole numbers they shake and shift during movement. Im so used to doing this but it takes up huge amounts of time and seems ridiculous but I’ve never been able to find a solution. The “snap to pixels” setting doesnt seem to help the problem.

thanks for any suggestions
