In | Duration of the fade-in at the beginning of the layer, in seconds. Range: 0s to 10s; Default: 0.5s |
|
Out | Duration of the fade-out at the end of the layer, in seconds. Range: 0s to 10s; Default: 0.5s |
Usage
This effect automatically animates the layer opacity. The results are exactly the same as using keyframe animation with the Opacity property in Blending & Opacity, but this effect is provided for convenience.
Unlike keyframe animation, the fade times remain consistent and anchor to the ends of the layer, even when the layer is trimmed, which can be useful when working with many layers.
To use this effect, just add it to any layer, then set In and Out to the desired durations.
You can set In to zero if you only need to fade out, and vice versa.
Keyframe Animation
Although it is possible to create keyframe animation for the In and Out properties, it is not recommended, as the results can be confusing. If you need additional opacity animation, just use keyframe animation with the Opacity property in Blending & Opacity (the opacity adjustment from this effect stacks with any existing opacity keyframe animation)
Use Cases
- Fading to Black: Set the project background color to black, then use this effect on the last layer in the project, setting In to zero and Out to the desired fade time. You can also do the opposite: Create a rectangle shape layer that covers the whole screen, and apply this effect with Out set to zero, and In set to the desired fade time.
- Cross-dissolve Transition: Create two layers which overlap by the desired dissolve duration, with the second layer on top of the first layer (for example, for a 2-second dissolve, create two layers which overlap by 2 seconds). Select the second (top) layer, and apply this effect, then set the In to desired cross-fade duration (the same as the overlap duration) and set Out to zero.
