Adding Effects II: Setting a Time Range. (Arrange editing mode)
To add an effect within a time range, first set the time range by double-clicking in the appropriate places in the “parent” on the Timeline. This will create two marking pegs. The “parent” can be an orange video bar, a pink effect, or a yellow group.
A bright yellow line will appear between the two pegs. This is the range over which the effect will be applied.
You can now add an effect by either right-clicking on this yellow line, or by clicking the “Add effect” button.
Choose the effect you wish to add and click “OK” (2x).
