I'm sorry, but what does THAT have to do with stop motion?

Hi, Do you want this to be done in an all puppet film? because for live action you could just simply download some type of program like composite lab and use the particle generator, and for a broom flying, you could just suspend it on wire painted green and film on a green screen. hope these suggetions help.

Before we send the kid off to green screen land, may I suggest he try his hand at some good old fashioned smoke and mirror effects? Here's an image I posted in another thread: http://www.stopmotionanimation.com/dc/user_files/12875.jpg And here's the "smoke and mirrors": http://www.stopmotionanimation.com/dc/user_files/12867.jpg The "sunbeam" is reflected in off a front-surface mirror placed in front of the camera at a 45 angle to the lens. It's a relatively simple matter to use cut-outs or other artwork for anything you want to layer onto the background setting. In this case, the sunbeam is just a piece of colored construction paper dangling against a black background, but you could just as easily create a magical zap from a wand, or just about anything. You can animated the reflected art, or gradually reveal it by covering it with a piece of black cloth then slowly slide the cloth away as you animate your scene. Cheers!

Hasn't Harry Potter Book 4 been done as a movie already? :P The easiest way to make some kind of effect - like light rays or lightning zaps - come out of a wand is probably to paint it on afterwards. I just used TV Paint to add some blue energy fields coming out of a magician's hand, but if you have the much cheaper Photoshop Elements, or any other image editing program with layers, you can do it. You have to load one frame at a time and save the modified version, so it's slow but it's possible, and I know one professional who does exactly that in Elements. If you want to do it in-camera, the same method Grecodan used for the sunbeam could work for a lightning flash effect. Just paint 3 or 4 different zaps in white on a black card, and place them so the glass will reflect them. You can cycle through the different painted zaps over and over for as long as you need them. Even simpler and more low-tech, if you don't mind being simple and cartoony, is to have paper cutouts and just stick them on the end of the wand. I did muzzle flashes that way. I put some glass in front of the camera and used a blob of vaseline on the glass just where the paper flash was, to blur it so it didn't look like a cutout. But if you are animating simple clay figures, the cartoony approach is probably the way to go anyway. Flying - use a wire or rod to hold the broomstick up. With TV Paint, Photoshop etc, you place an image of the background without the wire and broom in the bottom layer. Put the image of the broom flying in the top layer. Erase the wire so you see the background that should be behind it. Save the combined image. You don't need to shoot greenscreen for that. But if you did, you paint the wire out with green. Then you key it over the background. Or - frame it so either the front of the broom handle, or the back end of the bristles, are just outside the edge of the frame, and support it from there. Green screen: What framegrabber software will you be using? (If you don't know what I mean, click on Handbook in the grey strip at the top of the page, and do some reading. You need a bit of basic knowlege before you even know what questions to ask.) Some frame grabbers can do greenscreen keying right there. Otherwise you do it in another program like After Efects, Photoshop, TV Paint. However you do it, you need a green screen - could be green card, cloth, something painted green - and you need to light it evenly so it comes up mostly the same shade of green. Put your puppet well in front of it - a metre gap is good - so you can have different lights on the puppet. The puppet should avoid any green colour in it - including greenish blue, and greenish yellow. It needs to be far away enough that you don't get green light reflecting off the screen onto it. The program will select a shade of green as the chromakey colour, and make it go transparent. The fewer shades of green in the background, the better. You need to look at the program - StopMotion Pro, Dragon, whatever - to see how you do it.

thanks i am using dragon stop motion these are all so help full it dosent have green screen i dont think

Posted by Nick H, on 2010-03-29 21:24:58

Probably not, Dragon was developed mainly for professional work where you would use another program for chromakeying.
