Created by VinhSon Nguyen, of CreativeDojo.net, Heatwave is a realistic rippling heat distortion effect, with controls for intensity, direction, speed, amount and more.
- Drag the uni.Heatwave effect onto your clip.
Modify the Effect
- Choose the type of distorted wave applied to your image from the Wave Type drop-down menu. The Default, Billowed and Ridged options will all give you differently styled patterns of waves that distort your footage.
- The Heat Intensity slider allows you to increase the overall strength and depth of the effect on the footage when brought up towards 100.0 or to decrease the effect, making it more subtle when brought down toward 0.0.
- You can change the angle of the direction the heat waves are moving by adjusting the Flow Direction slider.
- As the Heatwave effect is already animating for you without keyframes, the Flow Speed controls allow you to adjust how fast the heat waves animate across the screen.
- The Blur Amount slider allows you to control how much blur appears in the heat waves.
- Found under the Distortion Settings the Heat Size, Heat Detail Amount and Heat Detail Scale all allow you to make adjustments to the size and scale of the noise pattern of the waves.
- The Heat Blur Settings group control the blur applied to the waves.
- The Blur Size control affects the size of the spread of the blur across the waves.
- The Blur Feather slider allows you to soften the edges of the blurred areas, blending the effect across the frame.
- The Blur Detail Amount and Blur Detail Scale sliders allow you to make adjustments to how much detail is found within the blurred areas. Bring these controls up towards 100 to bring out more detail or turn them down to smooth the detail out.
- Blur Quality sets the quality of the render, and how long it will take to render out the effect.
- The Mask Options Group is useful to isolate the Heatwave effect inside a masked area in the composition.
- Use the Shape drop down menu with a default Ellipse option, Rectangle, or Layer option which is connected to the Mask Layer control and allows you to set the shape of the mask to whatever Layer in your composition or project is selected in the Mask Layer drop down menu.
- The Invert checkbox when checked “On” will switch the blur to occur outside the selected mask shape instead of inside. The default is “Off” for this control.
- Point A crosshair control corresponds to the position of the top of the mask image and Point B controls correspond to the bottom position of the mask. Moving these points will squash or stretch out the shape of the mask, as well as move its position.
- The Radius control will spread the influence of the masked blur outwards from the center.
- The Feather Size will increase the translucency in the edges of the mask along a gradient. The Feather direction will pull the transparent gradient towards the center of the mask if turned down towards -100 or out towards the edges if turned up to 100.
- The Mask Channel drop-down allows the blurred area to respect the Alpha or the Luminance channel of the selected Layer.
- Mask Scale will scale your mask up or down in the range from 0-400% across the image.
- Mask Position allows you to move the position of the mask along the X and Y axis using the cross-hair or numerical controls.
- The Output drop-down menu allows you to view the different components of the Heatwave effect individually. By default this menu is set to Final Image, which shows the end results of all the settings applied to the footage. When selected the Distortion option shows the noise pattern isolated on the screen, this is especially obvious when viewing it animated in the timeline. The Blur option reveals the map of the blur on the footage, which is helpful to view when adjusting the Heat Blur Settings group. The Mask and Mask Overlay options are useful for viewing the effects of the Map Options group.
- The Heat Bias control allows you to adjust the overall Heatwave effect upon the composition. Turn this control up to 100 to make the effect more subtle or turn it down to make it more prominent.
