To create a lightsaber effect in Final Cut Pro, you can follow these steps using built-in tools and third-party plugins. Below is a method using masking and glow effects, plus options for plugins if you want a faster workflow.

🔧 Manual Method (No Plugins)

✅ Step 1: Prepare Your Footage

Import your video clip where the actor is swinging or holding a prop (ideally a stick or rod for tracking reference).

✅ Step 2: Add a Shape Mask for the Blade

1. Go to the Effects Browser and search for “Draw Mask.”
2. Drag the Draw Mask onto the clip.
3. Use the pen tool to draw the shape of the lightsaber blade frame by frame (rotoscope). Place four points to make a rectangle covering the blade.

✅ Step 3: Add the Glow Effect

1. In the Effects Browser, search for “Glow” and drag it onto your masked clip.
2. Adjust:
   • Glow Amount
   • Radius
   • Color (to green, blue, red, etc.)

✅ Step 4: Feather & Soften Edges

• Inside the Draw Mask settings, increase Feather and Falloff for a smoother, more glowing blade look.

✅ Step 5: Animate the Blade (Keyframing)

If the blade moves, you’ll need to keyframe the mask to follow the motion:

1. Go to the start frame, set the keyframe for Control Points.
2. Move frame-by-frame, adjusting the mask to match the blade position.
