Here is what I can suggest:

For anything you want to show that is flying, jumping or just plain floating you can use either one of two methods: chrome key “green screen” or layers/erase editing.

For the Chrome key method:

1. Take a photo of the background without the minifig and the broom, just the background. Make sure the lighting is the same for both photos!
2. Take a photo of the minifig on the broom on a green or blue brick inside the background that you just took a photo of! Again, same light level is critical because if it changes you will see the difference in the two photos!
3. For Chrome key you will be using a green screen affect where you can take a shot of the minifig on a broom and you use a specific color bricks “like green or blue” that is different than any other color on the minifig or broom. This way when you go to edit the brick color and have it removed you won’t lose the same colors on your minifig or broom! So you take a photo of the figure on the broom within the same background set on a green brick and them move the minifig a little or the green brick and then add another brick to make it higher, take a photo and continue moving the brick and adding bricks till you move the minifig and the broom either across the set or up off the top of the screen.
4. Now you have to edit each one of these image with an editor that can do chrome key. First let talk about Chrome Key: So the image or video editor will let you pick the color of the object you want removed and that color become transparent/see through! Some programs give you multiple times to pick a color and have it removed such as iKITmovie. I use Fluid Mask 3 which lets you tag a color or section of the image and it removes all of that color from the image. Very cool program! You will have to edit each photo this way by removing the green bricks using chrome key removal software and you will be left with an image that shows the minifig and the broom. You take this image and place it on top of the back ground image you took in the beginning. Now you have the minifig on broom floating over the background image. Tada! You have a flying minifig on a broom. Put them all in a video at 15fps and you have a flying minifig!

For the Layer and erase method:

1. Take a photo of the background without the minifig and the broom, just the background. Make sure the lighting is the same for both photos!
2. Take a photo of the minifig on the broom on a green or blue brick inside the background that you just took a photo of! Again, same light level is critical because if it changes you will see the difference in the two photos!
3. Remember you can use a Lego brick, a stand, your hand, basically anything that will hold the minifig and the broom. Whatever you use the holds the figure, make sure it is behind the figure and not in front because this is what you will be erasing from the image.
4. Take your photo of the minifig on the broom and move it a little, continue this method until you have all the shots of it moving off the screen.
5. Now you need an image editor that will do layers. I use DrawPlus5x but you can get 4x and it is really cheap. Drawplus is a graphical design and editor program. So you open a new drawing file and insert the background image into the drawing. Next you insert the photo with the minifig on the broom and place it on top of the background image but on another layer. This is critical because whatever you erase from the top layer will let the background layer show through. So you start erasing anything that was holding the minifig and broom from the image. Usually you can make the pointer large or small to erase larger areas or small pin point areas with ease. When done you will have the minifig on the broom floating over the background image and you minifig will look likes its flying!!!

Something that is important to remember when using either the chrome key method or the layer erase method: make sure your focus and quality of the image that will be flying or floating is high quality and with good light for a nice clean edge. The more you have a clean edge of the minifig, the better the editing will be able to remove the unwanted erase of the photo.

Casting spells or blasts:

For casting spells or showing blasts you can do pretty much the same method but you will first need to find the image of the spell blast or flame or mist or whatever you want to show up in the image. Usually a spell blast or flame image will be created with chrome key background, which lets you place it on top of another image and only the flame or blast shows up. These are the type of images you need to use as spell blasts or flames. You can Google them and download most for free.

When you get the image you want just use the layer method and place it on top of the image that will show the spell cast. Then save that image. Move the flame a little and save the image, continue until you have all the photos showing the flame moving or expanding across the screen. That’s it! You can really use any type of image and place it on top of your minifig or in front of the minifig that is casting the spell. You can even make it look as if it is coming out of the minfigs hands by placing the image right in front of the minifig and keep moving it across the screen image after image after image!

As always there are a huge amount of tutorials on Youtube that will show these types of editing tricks.

Hope this information helps out!
