 2: End Clip : This clip will be revealed at the end of the transition.


TransFlow   CONTROL PAGE

Restart  (Pushbutton)
     Restarts the flow. Please note that this is a physical simulation, the whole point of which is that it evolves over time. It isn't possible to independently calculate frames at random, nor is it at all straightforward to calculate different frames at different randomly chosen resolutions. This can make this effect unsuitable for use in some background rendering systems.

Viscosity  (Number  Min: 0.001, Max: 100.0, Default: 0.01)
     Viscosity of the fluid. The higher the viscosity, the more reluctant the fluid is to flow and the quicker any flow comes to a halt in the absence of applied forces.

Swirl  (Number  Min: 0.0, Max: 1.0, Default: 0.0)
     The higher this control, the more pronounced swirls (vortices) will be and the more "detailed" the flow will seem.

Buoyancy Mode  (List Box  Options: None | Input Luma | Pressure Input, Default: Input Luma)
Whether to calculate internal buoyancy forces, and, if so, how. Input Luma will use the luminance of the input image to calculate the relative density of the fluid and the Rise Fall control governs the rate. Pressure Input uses the input luminace as a pressure force controlled by Pressure Force.
RiseFall  (Number  Min: -10.0, Max: 10.0, Default: 5.0)
     Tendency to rise (positive) or fall (negative) when Input Luma is used as the Buoyancy Mode.

Pressure Force  (Number  Min: 0.0, Max: 1.0, Default: 0.0)
     Strength of pressure force derived from density gradient of the input clip.

Restart On Process  (Checkbox  Default: Off)
     If available turn On immediately before processing to ensure that the first frame is taken from the clip with no flowing affecting it.

Random Mode  (List Box  Options: Type 1 | Type 2, Default: Type 1)
There are two seperate modes provided for generating random forces in the flow. The BType 2 option is a good approximation of real world turbulence that introduces complex "eddies" into the flow.
InitialRandom  (Number  Min: 0.0, Max: 1.0, Default: 0.0)
     Initial random velocities added at the start only to push the image.

EachRandom  (Number  Min: 0.0, Max: 1.0, Default: 0.0)
     Random velocities added each frame to augment the motion.

Eddy Size  (Number  Min: 2.0, Max: 30.0, Default: 16.0)
     Determines the number and size of "eddies" induced in Type 2 turbulent flow. The larger the value, the smaller the "eddies" will be.

Finer Grid  (Checkbox  Default: Off)
     Turn on/off the higher grid resolution option. On Uses a grid of 256x256. This is mainly useful for increasing the resolution of any barriers used, however processing speed will be slower.
Off Uses the speedier grid resolution of 128x128.

Transition Length  (Number  Min: 2, Max: 250, Default: 25)
     Number of frames over which the transistion takes place.

Transition Start  (Number  Min: 0, Max: 500, Default: 5)
     The transistion will start from this frame.

Fade  (Checkbox  Default: On)
     Turn on/off the fade out function. This ensures the Start clip will disappear by the end of the transition.

Fade Length  (Number  Min: 2, Max: 250, Default: 10)
     How long the fade lasts. The fade will start at the chosen number of framesbefore the end of the transition.

Slip  (Checkbox  Default: Off)
     Turn on/off to display and use the Slip controls.

Slip Start  (Number  Min: -500, Max: 500, Default: 0)
     Slip the start clip to the desired starting frame.

Slip End  (Number  Min: -500, Max: 500, Default: 0)
     Slip the end clip to start the transition from this frame.

Output  (List Box  Options: Result | Result Over Background | Matte | Flowed At Grid Res | Grid, Default: Result Over Background)
What to output.
Result is the flowed image.
Result Over BackGround is the flowed image composited over the background clip.
Matte Matte of the flowed image.
Flowed at Grid Res The output resampled to the grid resolution.
Grid A representaion of the grid.
PreMultiplyForeground  (Checkbox  Default: Off)
     Have the colours in the foreground clip premultiplied by its alpha (density) before compositing.

Use Gravity  (Checkbox  Default: Off)
     Turn on/off gravity.

GravForce  (Number  Min: 0.0, Max: 1.0, Default: 0.1)
     Strength of the gravitational force (which acts on density and is pointing in a downwards direction if the GravAngle is 0.0).

Gravity Direction  (Number  Min: -360, Max: 360, Default: 270)
     Rotates the direction of the velocity force vector (at 0 rotation, the vector is (1,0)).

Use Velocity A  (Checkbox  Default: Off)
     Turn on/off the velocity force. The velocity "force" is a constant velocity, defined to exist within a user defined rectangular region. It is very useful for inducing constant flows and "jets" in the fluid.
The velocity is a unit vector in the X direction. The direction can be adjusted by the Velocity Direction control. The magnitude can be adjusted by the VelAdd control.

Centre A  (Position  Default: 0.02,0.5)
     Center of the rectangular region in which the velocity force acts.

Scale A X  (Number  Min: 0.01, Max: 2.00, Default: 0.08)
     Width of the rectangular region in which the velocity force acts.

Scale A Y  (Number  Min: 0.01, Max: 2.00, Default: 0.08)
     Height of the rectangular region in which the velocity force acts.

Velocity A Direction  (Number  Min: -360, Max: 360, Default: 0)
     Rotates the direction of the velocity force vector (at 0 rotation, the vector is (1,0)).

Vel Add A  (Number  Min: 0.0, Max: 1.0, Default: 0.5)
     Scales the magnitude of the velocity force vector.

Use Velocity B  (Checkbox  Default: Off)
     Turn on/off the velocity force. The velocity "force" is a constant velocity, defined to exist within a user defined rectangular region. It is very useful for inducing constant flows and "jets" in the fluid.
The velocity is a unit vector in the X direction. The direction can be adjusted by the Velocity Direction control. The magnitude can be adjusted by the VelAdd control.

Centre B  (Position  Default: 0.62,0.2)
     Center of the rectangular region in which the velocity force acts.

Scale A B  (Number  Min: 0.01, Max: 2.00, Default: 0.08)
     Width of the rectangular region in which the velocity force acts.

Scale B Y  (Number  Min: 0.01, Max: 2.00, Default: 0.08)
     Height of the rectangular region in which the velocity force acts.

Velocity B Direction  (Number  Min: -360, Max: 360, Default: 270.0)
     Rotates the direction of the velocity force vector (at 0 rotation, the vector is (1,0)).

Vel Add B  (Number  Min: 0.0, Max: 1.0, Default: 0.5)
     Scales the magnitude of the velocity force vector.

Remove Net Force  (Checkbox  Default: Off)
     When Off for every frame the active forces are added to the current state of the force field pushing the image about. Removing the "Net Force" only applies the currently calculated forces to the motion so the fluid will tend to stay in the image and not flow off. If random forces you get static turbulent flow.
