Well effects lab was made more for this. I did this quick test in composite lab. It's not near as good as what Vision or effects lab can make, but it's better then nothing.


First get the video clip you want.


Then Key out the back ground. (I used a color dif. key, it seems to produce the best results.)


Next duplicate the foreground clip by right cliking it, hit copy, then above paste.


Now grade it to where the brightness is all the way up.


Now draw a mask around the blade and change it to invert. Feather the edges. Make sure you dont cover the whole blade, you want to keep the edges.


And now you are done.


Like I said, it's not going to give you the best results, but is better than nothing. Try putting a glow on the top layer, and experiment a little. This took me less the a minute. Good luck. Be sure to post some pictures of your work when you are finnished.

The pictures I used are not mine. I saved them off of the internet. I did do all the stuff in comp lab though.

Erm, nice post and all, but that isn't even close to what he asked...

To have something fly into your hands you could do a few things:

Creative editing and compositing: Show a closeup of the belt, cut to a wideshot. Use a stock image of the lightsaber hilt (get a still from video in your camera or something) and isolate the lightsaber by drawing a mask and inverting it. Scale it down so it looks like it is on his hip and change the color of the hilt to make it match the color of the scene. If you take the picture with the camcorder from where you shot the clip, you won't have to do that part. Then animate it to fly toward your actors hand, cut to a closeup of his hand catching the hilt and igniting it and have the following action of the scene take place.

String: Tie string to the hilt and make the string very long. Have someone stand far off set holding one end of the string. The hilt will be attached loosely to the belt and the string will go over the arm that is going to catch it. When the guy off set pulls the string hard, the saber will go toward the hand and your actor can catch it. If it's a wide shot, the string will not show up. If it's a closeup, use a tripod and get footage of the background without the actor. With this background plate you can place it below the main clip on the timeline and use a garbage matte to effectively hide the string. Though this way, you can't hide string in between the camera and the actor himself.

String 2: Have someone stand above the actor in a tree, or something. It would be the same idea as the first idea, but he would pull it from the belt diagonally upward and the actor would catch it.

Implied: Have someone lay down below your actor and film a waste up shot. Have the guy on the ground throw the saber as straight as possible to your actors hands.

There are other complex ways to do it, but in the end it could look bad if you don't do it right, so sometimes practical is the best way to go. I know it's cool doing stuff digitally, but I don't think digital is your best option for this because the part that you implied was composited (the hilt) has to interact with the actor. So yeah, you could composite a still to fly into the actors hand, then when the actor clasped his hand around the imaginary prop, you would mask around the part of the hand that comes between the camera and the hilt, then animate the hilt to stay with his hand. This would take really long to look good and you'd probably need a wide shot to hide the fact that: the pixels are stationary (unless you used a masked video of the hilt), it isn't moving properly in 3D space because it's 2D, shadows aren't interacting properly, it's not tracked perfectly to the hand that holds it, it's specular surface doesn't interact properly with lights, etc. Compositing here would also limit interaction and the action of your actor.

Use a rubber band to connect the hilt to your belt. Have your actor hold it in his hand, with the rubber band stretched out, then open his hand so it flies back to the belt. Cut out just the bit of footage you need, and reverse it.

Serpent thanks for such a descriptive reply very helpful and axeman what a simple but good idea could use a green band and cut it out
