This filter should do what you're looking for, the footage plays back at regular speed, but skips a specified number of frames. I'm playing around with the settings on 24fps footage, and a Strobe Rate setting of 4 skips about 15 frames, while a setting of 5 skips half a second (12 frames at 24P). One of those settings should do the trick for you. If not, play around with the sliders until you get what you want.
If you're looking to do a slow-mo stop motion effect, right click the clip, select Change Speed..., and set it to 6.67% (6.67% of 30 fps = about 2 fps). Be sure to uncheck Frame Blending to get that jumpy look you're going for.
