Source The media player which will be used to play the clip for the animated transition.
Pre Multiplied Key Identifies the key signal of the media player clip as a pre-multiplied key.
Clip The clip level adjusts the threshold at which the key cuts its hole into the clip that
is playing back through the media player. Decreasing the clip level reveals more
of the background. If the background video is completely black then the clip
value is too low.
Gain The gain adjustment electronically modifies the value which allows the softening
of the edges of the key in the clip that is playing back on the media player. Adjust
the gain value until the edge softness is desirable but the background video
luminance (brightness) is not affected.
Invert Key Inverts the key.
Clip Duration Clip duration refers to the length of the animation. The duration should normally
match the length of the animation. It can also be used to trim out the end of the
clip.
Trigger Point Trigger point is the time at which the switcher will start the background mix
transition, which will occur under the animation. Usually, this is the point when the
animation is full screen.
Mix Rate The mix rate specifies the duration of the mix that will occur between preview
and program under the animation. To specify a cut instead of a mix simply set the
rate to 1 frame.
Pre Roll Pre roll is a trim in that can be used to trim the beginning of the clip. The
maximum preroll time is 3:00 seconds.
