Indeed, there are a lot of parameters in that particular filter, which can make generating a quick effect a bit more difficult that one might want. However, there are a couple of options for you:
The first approach to this would be to use the Jitter Basic filter instead. The click on the preset loader pop-up and select jitterPositionX and you should be at the tweaking stage within seconds of applying the filter.
The other approach is to use the Film Damage filter instead and disable everything except for the Camera Shake. And you're ready to fine tune the jittered result.
