I need some help with the light saber I go frame by frame(rotoscoping)my laser where I want to put it i have a scene where the the sword is still for about 3-4 seconds long. I put the lights where i want it because it is still. then when I go play it back the light saber moves across the screen or rotates when i have not do anything for it to do that kind of function. What can I do to fix this problem.

Every time you make an adjustment to the lightsaber, you create a keyframe. EffectsLab automatically interpolates the frames in between.

So, if you use the rotate tool on frame 10, then don't use it again until frame 43, EffectsLab will automatically rotate the lightsaber evenly between those two keyframes, from frame 10 to frame 43. The trick is to use the same tools to move the blade each frame, so you don't introduce unnecessary keyframes. Go back into the lightsaber effect and delete any rotation keyframes you have created. Then you may need to reposition the blade on those frames, but I'm pretty sure that will be the quickest way to fix it.

Fore more information, take a look at the knowledgebase article, "What is Tweening, and how does it work?"

As I said, a better understanding of how tweening works will help you fix the situation. The article I linked to previously explains it. I may have been incorrect in my assumption that it was the rotate tool that caused the problem; its impossible to say without seeing the project or getting a lot more additional detail. However, the principles behind what I was trying to explain are still what is causing the issue. I'm fairly sure.

When you say Laser, are you referring to the Laser effect, or the Neon Light effect? You mention both in your first post, and the two are controlled completely differently, so I guess the first step is to determine which engine you are actually using.
