Range Selector 1 consists of three main parameters – Start, End, and Offset – plus an Advanced section which we’ll explore later. The default values of Start = 0%, End = 100% mean that all characters are said to be included in the range. Slowly scrub the Start parameter – the beginning of the title jumps back up to its original placement in the Comp panel. When characters fall outside the range selection (also known as excluded), they are no longer affected by the Position offset value. Set the Start value to 100%; when Start = 100% and End = 100%, no characters are included in the range.

Return the Start value to 0% and scrub the End parameter. The result is similar, but in this case the characters at the end of the title are excluded and return to normal.

The selector bars (vertical lines plus arrows) in the Comp panel indicate the Start and End of the range selector. They are only visible when the animator group or one of its parameters (if it has only one Range Selector) is selected. Dragging the selector bars directly in the Comp panel also changes the Start and End values.

Set Start to 0% and End to 33%, so only the first word is included. Slowly scrub the third parameter: Offset. This moves the Start/End range “through” the text, while maintaining its relative spacing.
