Transitions between two input clips using a vortex
warping function. The first clip is warped away and faded out while
the second clip is unwarped into place and faded in. The Dissolve
Percent parameter should be animated to control the transition speed.
In the Sapphire Transitions effects submenu.
Foreground: The current layer. Starts the transition with this clip.
Background: Defaults to None. Ends the transition with this clip. If this input is
not provided, a fully transparent background is used, showing
whatever is behind it. Note that the background can not be
warped during the transition unless this input is provided.
- Transition Dir:
Popup menu, Default: Dissolve Off to Bg.
Selects the direction of the transition.
- Dissolve Off to Bg: transitions from the current layer to the Background.
- Dissolve On from Bg: transitions from the Background to the current layer.
- Auto Trans:
Popup YES-NO, Default: No.
If enabled, a transition is performed automatically between
the first and last frames of the layer. If this is off, the transition is
performed manually by animating the Dissolve Percent parameter.
- Dissolve Percent: Default: 0, Range: 0 to 100.
Auto Trans must be disabled for this parameter to be
used. It determines the transition ratio between the Foreground and Background
inputs, and would normally be animated from 0 to 100 to perform a
complete transition. The curve controlling this parameter can be adjusted
for more detailed control over the timing of the dissolve.
The Slow In and Slow Out
parameters, if positive, also adjust the transition ratio internally
for a smoother start and/or end to the transition.
- Center: X & Y, Default: [360 243], Range: any.
The location of the vortex center in screen coordinates
relative to the center of the frame. This parameter can be set by
enabling and moving the Center Widget. Note that moving the vortex
center can also cause the vortex size to change so that the current
value of Wipe Amt remains correct.
- Vortex Amount: Default: 72, Range: any.
The amount of vortex rotation, in approximate
degrees at the edge of the frame.
- Rel Amount2: Default: -1, Range: any.
The relative amount of the second clip vortex rotation.
If this is positive instead of negative the second clip will be
unvortexed from the opposite direction.
- Rotate Amount: Default: 0, Range: any.
If non-zero, a rotation is also added to the
warping. Make negative to rotate the inner and outer regions in
- Inner Radius: Default: 15, Range: 0 or greater.
The radius from the center at which the vortexing is
phased in. This can be used to reduce excessive distortion and
aliasing at the very center of the vortex.
- Slow In: Default: 0.5, Range: 0 to 1.
If positive, causes the transition to start more gradually.
- Slow Out: Default: 0.5, Range: 0 to 1.
If positive, causes the transition to end more gradually.
X & Y, Popup menu, Default: [Reflect Reflect].
Determines the method for accessing outside the borders of the
- No: gives black beyond the borders.
- Tile: repeats a copy of the image.
- Reflect: repeats a mirrored copy. Edges are often less
visible with this method.
- Filter: Check-box, Default: on.
If enabled, the image is adaptively filtered when it is
resampled. This gives a better quality result when parts of the image
are warped smaller.
Popup menu, Default: Normal.
Determines the method used for dealing with
- All Opaque: Use this option to render slightly faster when
the input image is fully opaque with no transparency (alpha=1).
- Normal: Process opacity normally.
- As Premult: Process as if the image is already in
premultiplied form (colors have been scaled by opacity). This option
also renders slightly faster than Normal mode, but the results will
also be in premultiplied form, which is sometimes less correct.
If your image has sharp color changes where the matte
channel also has sharp edges, you may get better results with Normal
