Final Cut Pro: How To Use Keying
Chroma keying composition is a technique used to mix up two picture frames, and then to remove a color of one picture or make it transparent to reveal the other picture behind it. In this, a blue screen is inserted into the background of other movies. This technique is widely used in the film industry and also in photography, to produce a good quality picture or video with great effects in it. The following steps will tell you how to use chroma keying in Windows Movie maker to produce a high quality video.
Step 1: Choose a Background Video
First, you should choose a background video. This will be the material you want to show in your blue area of that blue screen. This can be any video, like a home video or any video you have in your computer.
Step 2: Light the Background
Your blue screen can be flat, which may look like a blue wall or surface. But make sure you light the background equally, as any differences will make the final movie look unprofessional. Keep your background in mind, as you do not want to make your blue screen larger than the background screen
Step 3: Transfer Blue Screen
Now it's the time to transfer your blue screen to your computer.
Step 4: Add Blue Screen File
Add the blue screen transition file to your windows Movie Maker Program. You can search for the code by going on the Windows Movie Maker website and searching for a blue screen transition. Copy that code into notepad and than save it as "bluescree.xml" into C:\Program Files\Movie Maker\Shared\AddOnTFX. If your computer does not contain this folder, then you can make it.
Step 5: Combine Videos
Now its time to combine both videos in Movie maker. Import both videos on movie maker and drag the background video on the timeline followed by the blue screen.
Step 6: Drag the Blue Screen
Now go to the "tools" menu and click on "video transitions". From there, choose the labeled "blue screen" and just drag it between two videos on the timeline. You should click on the left edge of the blue screen box and drag it on the left so it overlaps the background scene as much as the program allows you.
Step 7: View and Save Video
Now, view your final video and save it if you think that this was what you were trying to produce (if you can see blue edges in your blue screen video, it means that your blue screen was not uniform, and you should try another blue screen).
Chroma keying will help you to produce what you want and will allow you to put backgrounds in a video or picture as you desire. Chroma keying can also be used in many other programs, like AVi, and in many other video players and programs.Popular P&S Cameras for High Quality Photos:
