Maybe I can help. If not, shoot me
With lightsabers, it's best to work from shot to shot. Use your NLE to split the shots and angles apart after you've established what you want the final film's layout to be. Esport each shot and bring each separately into AlamDV.
Place the lightsword on the timeline for the shot you are editing. Then right-click and drag to extend the span of the effect. Next, LEFT-click on the asterisk and drag it to where you had dragged the other bar to extend the span. (If you are altering where your spans are and not going completely in equilibrium with your alterations, I can't help you. I've never done that, and I don't know how to start. If you're doing as I seem to be explaining, then continue reading).
Now that you have developed the length of time the plugin will be on the screen, go to the beginning of its duration, and place your first quad on the frame. I would recommend using the AlamDV1 I-face (four-point click), as it is a little easier to deal with. Once you have placed it, go onto your next frame, and so on and so forth. When you're done, just export that shot and move onto the next.
As a side note, I'd recommend keyframing every frame, unless tweening is absolutely necessary. Otherwise, if you make any changes, in the middle, you could fudge up what you did in the beginning of the clip and be forced to start over.
When every clip is done and exported, bring it back into your NLE and put them all in order. Done.
Hope this helps. Hope I am not shot.
