For each animation the object contains multiple keyframe tracks

In Stages you can control, among other things, transparency, fading in and out, screen panning, the motion path and the text display in the Timeline, over Key frames.
This allows you to match the effects by time.
If you are using music or sound, the effects can be matched precisely to the audio with the help of the Key frame track, but the effects are also matched better to each other with the help of the Key frames.
A Key frame always stands for a particular setting, which is displayed at a specified time. The values which lie between the two Key frames are are automatically generated by Stages.
In this way you can completely control a process of transparency, a movement or a cross-fade using Key frames.

Open Keyframe Tracks for Text Object

The symbols to open and close the Key frame Track can also be found on the individual Objects.
If you wish to save space in the Timeline and prefer not display every individual Key frame Track to be displayed, simply close the others. Then use the button to open the Key frame Track, which is located on the respective object.

Opened Keyframe Tracks

First of all open the Key frame Tracks of the Object. Depending on the type of Object, there are differing Key frame Tracks available. You can see which Effect or which Property can be set for each Track thanks to the symbols at the beginning of each Key frame Track.

If you wish to edit the Key frames in a particular track, first click on the relevant Track. This is then highlighted by a slight enlargement.

Then click anywhere within this Track to create a Key frame. This Key frame can create a new Motion Marker in the Track for the pan shot whose Properties you can, for example, set precisely in the Layout designer.

A Key frame in the Track for Transparency creates a new point in the Transparency Curve. You see this curve with your ups and downs directly in the Key frame Track.
