3D Transformations (NewsEdit XT only)
All of the 3D Transformations can be used with each other.
Keyframes
Within the Video Effects Tool, some parameters are keyframeable and some
are not. That is, if a parameter is keyframeable, the parameter can change from
one keyframe to the next. If a parameter is not keyframeable, that parameter is
used for the entire effect and cannot change across keyframes.
The type of effect or 3D transformation is not keyframeable. The following
tables list the type of effect, its parameters and options, and whether each is
keyframeable.
