When you ran Ultra for the first time, you chose either NTSC or PAL. Regardless of which
video format you chose to work with, you can use video clips of either format as sources.
You can use still images with dimensions of up to 4096x4096 pixels as sources if the graphics
card supports that resolution. Ultra preserves the native resolution of all graphics sources up
to 4096x4096. One advantage of this is that when you zoom in the image remains crisp and
unmarred by the blockiness the comes from enlarging low-resolution graphics.
In general, however, the format of the video clips and the dimensions of the still images used
as sources should be consistent with the video format in which you'll output the finished clips.
If you assign a video clip to any layer other than the input clip, you may need to trim it or
set it to loop so that it ends at the same time as the input clip, if that's your goal. For more
information, see
"Looping the clip" on page
Creating elements for a set or individual layers
Virtual sets are bundles of visual elements that work together to produce the illusion of a
three-dimensional set. The virtual sets that come in the Master Sets Libraries are advanced
designs. Some of these virtual sets have foreground elements and multiple insets, each with a
letter designating which source it is. The Basic sets that are installed with Ultra let you achieve
comparable results using your own graphics for background and foreground elements. You
must apply an alpha channel where you want transparency through to the next layer in the
composited scene.
This section explains how to create the elements that make up a virtual set. The principals are
the same regardless of whether you're working in an image-editing application such as
Photoshop or a 3D application such as Maya™ or 3DMax™. Keep the following general
pointers in mind as you proceed:
Supported file types: PNG, JPEG, BMP, PPM, TIFF and Targa (TGA).
