How to Chroma Key in Windows Movie Maker
Chroma Keying or bluescreening is very easy to do and is very common. Every time you watch the weather, a
bluescreen is used. This tutorial will go over how to chroma key using a free but useful program called
"Windows Movie Maker". (we'll call it WMM for short)
Record your subject in front of a well-lit blue or green screen, and transfer the video onto
your computer.
Highlight the following xml code: (Source-windowsmoviemakers.net/forums)
<!-- windowsmoviemakers.net/forums -->
<TransitionsAndEffects Version="1.0">
<Transitions>
<TransitionDLL guid="{C5B19592-145E-11D3-9F04-006008039E37}" >
<Transition name="Bluescreen" iconid="12" comment="Makes first clip show
through blue areas of second clip">
<Param name="KeyType" value="1"/>
<Param name="Similarity" value="100"/>
<Param name="Progress" value="0.0"/>
</Transition>
</TransitionDLL>
</Transitions>
</TransitionsAndEffects>
Copy it, and paste it into notepad. Click File>Save As, and navigate to C:Program FilesMovie
MakerSharedAddOnTFX. (If you don't already have an AddOnTFX folder, right click then
New>Folder.) In the drop-down "File type" box, select "All types". Save the file as "bluescreen.xml"
Run Windows Movie Maker.
Import the video of your subject into WMM, and drag it down to the timeline.
Find the picture or video you want to show behind your subject. Import it into WMM, and drag it
down to the time line to the left of the video with your subject in front of the blue/green screen.
Now that your two video clips are in the timeline, go to your transitions and there should be
one that says "Bluescreen". Click it and drag it down to the timeline. Click the video of the
bluescreen and drag it over onto the other clip. Don't drag it to far because that will just make the
clips switch places. Keep going until the blue triangle disappears, then go back just a hair. (It will
make more sense when you try it)
Check out your preview and see if it worked.
Click File>Save Movie File to save your movie.
