I haven't been able to find out how to do this. All the websites keep showing how to rotoscope or do frame by frame special effects for the lightsabers.

If I have green surface on a stick, can I do green screen effect on it, thereby getting rid of the tedious frame by frame effects?

How do I do it? Can't find the fricking instructions

As far as green on a lightsaber, it probably won't work, not with Vision Lab though. You'd be better off using After Effects and some tracking software and putting black/white dots on the lightsaber to track it. Don't know if it'll work though.

If the lightsaber isn't moving, then you can add a key to select the green, then use the Neon Object to use the alpha shape created by the key to create the shape of the lightsaber automatically. However, in practical application, once the lightsaber starts moving, the motion blur makes it impossible to select the blade based on color, once again making it necessary to draw it on each frame manually. Frame-by-frame rotoscoping is how the experts and the pro's create lghtsabers, 'cause it still works the best.

Yup. But let's hope that in a few years, we won't need to do that because lightsabers will be real! (Anyone else REALLY wish they had a real one?)

Yup frame by frame is the best, sometimes you can skip a few frames when the saber isn't moving.
