Echo
Brief Description
Temporally accmulates images to create motion-blur
Controls
| Parameter / Script Name | Type | Default | Function |
|---|---|---|---|
Enabled / enabled | Boolean | On | |
Red / process_red | Boolean | On | Enable the red channel in output. Otherwise if there's a source the content of the main source is returned instead, else 0 |
Green / process_green | Boolean | On | Enable the green channel in output. Otherwise if there's a source the content of the main source is returned instead, else 0 |
Blue / process_blue | Boolean | On | Enable the blue channel in output. Otherwise if there's a source the content of the main source is returned instead, else 0 |
Alpha / process_alpha | Boolean | On | Enable the alpha channel in output. Otherwise if there's a source the content of the main source is returned instead, else 0 |
Mode / mode | Choice | Average | - Average - Screen - Minimum - Maximum - Blend To Front - Blend To Back |
Initial Opacity / initial_opacity | Float | 1 | |
Decay / opacity_decay | Float | 1 | |
Num Divisions / num_divisions | Float | 1 | The number of samples to use for the motion-blur. The higher the number is, the more accurate is the motion-blur when large motion is involved, but the slower it is to render. |
Shutter Angle / shutter_angle | Float | 180 | The shutter angle controls the time period over which light can pass. A wider angle increases motion-blur |
Shutter Phase / phase_type | Choice | Centered | - Centered: The shutter opens half the shutter duration before the current time and closes half the shutter duration after - Start: The shutter opens at the current time and closes after the shutter duration is elapsed - End: The shutter opens at the current time minus the shutter duration and closes at the current time - Custom: The shutter opens at the time determined by a custom phase: the phase is an offset on the shutter angle, assuming the shutter opens at 0 |
Custom Phase / custom_phase | Float | -90 | An offset to the shutter angle, assuming the shutter opens at 0°: A Shutter angle of 180° with a phase of -90° means that the shutter will be opened half a frame, centered around the current time |
Mask / mask | Image | - | |
Mix / mix_with_source | Float | 1 | Dissolves between the original image at 0 and the image with the effect applied at 1 |
