In the Object settings window, you will find the Transparency tab for almost all objects, which you can use to assign a specific transparency behavior. For example, it is possible to make an image or text slowly emerge from a black background and later disappear into it again. You can also make images and text appear semi-transparent on top of a previous image.
Set points in the blue area
To be able to create a transparency curve for your object, call the Transparency tab in the Object settings window.
A diagram with a blue background appears, whose y-axis stands for the opacity in percent, while the x-axis reflects the duration in seconds. Set points on the area between the axes with a mouse click. The lower the point is, the greater the transparency of the object will be. If the point is at the level of 100% opacity, the object is not transparent but completely visible.
Under Template you can choose from standard curves. If you have saved your own transparency curves, you will find them in the Custom curves section. Via the selection Remove curve, all marks are removed.
You will find the following icons that you can use to influence the transparency curve:
Transparency curve with four points
To define the transparency course, form a curve in the diagram. To do this, click in the blue background area. This will set a first point, and the curve will appear horizontally.
Now you can create more points by clicking with the mouse button, which can be moved as you wish. Each point represents a certain strength of opacity that the object has at a certain time.
In Stages, you can also control transparency using the keyframe track. To do this, open the keyframe track and click in the transparency track. Again, you have a curve whose ups and downs you can control with individual markers. The values between the keyframes are automatically calculated (interpolated).

4 Make object blink with generated curve
Generate rectangular curve
To make an object blink, let the opacity change at intervals - between 0% opacity and 100% opacity.
1 Click the Generate curve icon and select Generate rectangular curve.
Parameters for rectangular curve
2 In the following dialog, select the number of desired oscillations or their frequency.
Generated transparency curve
The transparency curve is calculated and drawn accordingly.
The object is now visible and invisible in alternating seconds, creating a blinking effect.
Further possibilities are offered by the "Transparency fluctuation" effect
