In many cases, 3D animation sequences can be overlaid over a video footage to
create a composite. First, you will need to import the sequence into MediaStudio
Pro, then overlay it over a video clip.
To import COOL 3D Production Studio image sequence:
1. In Video Editor click Insert - Image File - browse to your COOL 3D
Production Studio output folder.
2. [Shift] - Click on a first and the last files in the sequence to select all of them.
(Alternatively, click any image in the folder, then [Ctrl + A] to select).
3. Click [Open] or press [Enter] on your keyboard.
4. Move the insert-type cursor to a video track above the video clip to be overlaid
in the timeline pane and click the left mouse button once.
To overlay video with the COOL 3D Production Studio image sequence:
1. Click on the video track button
to select the image sequence clip.
2. Go to Clip - Overlay Options; set Type to Alpha Channel and Mask to
Overlay Clip. Adjust Soft Edge and Transparency sliders to desired values.
3. Click OK or press [Enter].
• Edge fringing or so-called aliasing of the images may spoil your composite.
To avoid jagged-looking edges watch out for the alpha channel that comes
with the imported 3D files. Be sure to output images with Straight Alpha
from these programs.
• If you didn’t work with alpha channels before, here’s a brief introduction. All
digital images could be separated into several channels. Most of professional
graphics software like Ulead Photoimpact have that kind of functionality. The
usual channels of an image are RGB - Red, Green and Blue. As you know,
these are the fundamental components of the white color.
• Alpha is the fourth channel, but unlike the RGB colors, it doesn’t serve the
purpose of defining a color of an image. It is used solely for telling your
computer everything about the image transparency.
• Alpha channel uses black to define full transparency and white to define
complete opaqueness. Shades of gray are semi-transparent places on the
image.
