Overview & Purpose
The AT Oscillate Size effect allows you to apply dynamic, oscillating scaling (size changes) to any clip on your Edit Page timeline. It mirrors the functionality of its Fusion page counterpart, offering controls for wave shape, amplitude, frequency, and damping around a central size offset.
Apply this effect by dragging it from the Effects Library onto your clip. All parameters are then adjustable in the Inspector.
Parameters
The parameters are identical to the Fusion Page Oscillate Size tool, adapted for Edit Page use.
Basic Controls
| Parameter | Description | Default |
|---|---|---|
| Amplitude | Determines the magnitude of the size change from the Size Offset. An amplitude of 1.0 with a Size Offset of 1.0 using a Sine wave will cause the size to oscillate between 0.0 and 2.0 times the original clip size. |
1.0 |
| Frequency (cycles/sec) | Controls how many times the size oscillation pattern repeats per second. This is frame rate dependent based on the timeline settings. | 1.0 |
| Wave Type | Selects the mathematical wave function for the size animation (Sine, Triangle, Bounce, etc.). | Sine |
Damping Controls
| Parameter | Description | Default |
|---|---|---|
| Amp/Damp Frames | The number of frames for the damping or amplification effect on the size amplitude. Positive values decrease amplitude, negative values increase it. 0 means no damping. | 0 |
| Damping Type | Defines the curve of the damping effect (Linear, Quadratic, Exponential, Logarithmic). | Quadratic |
Spatial Controls (Size Specific)
| Parameter | Description | Default |
|---|---|---|
| Size Offset | This parameter sets the baseline or middle size around which the oscillation occurs. A value of 1.0 means the oscillation is centered around the clip's original size. The final size cannot be negative; it's clamped at 0. | 1.0 |
Timing Controls
| Parameter | Description | Default |
|---|---|---|
| Start Frame | Delays the start of the size oscillation and any associated damping until this frame number within the clip's duration. | 0 |
| Phase Shift (degrees) | Shifts the starting point of the size oscillation wave (0-360 degrees). | 0.0 |
Common Controls
Standard effect common controls (Motion Blur, Quality, etc.) are available under the Common tab in the Inspector.
Usage on the Edit Page
- Open the Effects Library in Davinci Resolve (Edit Page).
- Navigate to Video Transitions > Fusion Transitions (or wherever Anim Toys effects are installed, often under Templates).
- Drag the AT Oscillate Size effect onto a clip in your timeline.
- Select the clip, and open the Inspector panel. Go to the Effects tab.
- Adjust the parameters as described above to achieve the desired scaling animation.
