Text-based objects are static text, marquee and roll. They have common transformation, content and general parameters.
A text object is used for different kinds of text fields in a fixed position. To add this object, select it from "Insert" main menu; alternatively select it from the "Insert" drop-down list of the tree context menu.
The text for the object can be specified in the "Text" field:
In the "Font" you can specify the formatting parameters, such as font family, size, font style (bold and/or italic).
|Please ensure that the custom set of fonts is installed on both working and playout stations.|
Select the "Word Wrap" checkbox to split long text into lines inside the text object box on the canvas without actual line breaks.
Select the "Right to Left" checkbox to enable the right-to-left languages writing style.
The "Vertical Direction" option enables the vertical orientation of the text in a line.
Select the "Subpixel Align" checkbox to enable the alignment with sub-pixel accuracy.
The "Horizontal Align" and "Vertical Align" parameters define the alignment of the text within the text object boundaries. The values are represented with the corresponding icons.
The "Spacing" parameters panel contains parameters for defining spacing behaviour between text characters, words and lines of text within the text object boundaries.
The results of these changes will be visible in real-time within the canvas area.
Marquee / Roll
The marquee object is most commonly used to create news tickers allowing the text to move from right to left on the screen. To add it to your scene, select it in the "Insert" main menu; alternatively select it from the "Insert" drop-down list of the tree context menu.
The roll object is similar to the marquee, except that the text slides from top to bottom or vice versa. To add it to your scene, select it in the "Insert" main menu; alternatively select it from the "Insert" drop-down list of the tree context menu.
Specify the text for the marquee / roll object in the "Text" field.
|Refer to previous section to learn more about text formatting.|
Go to the "Animation" section to specify the marquee / roll movement parameters.
Modes of Movement
There are two animation modes for the marquee / roll object – movement by percentage value (progress), and movement by absolute speed.
The "Progress" field defines percentage of progression of the text through the complete scrolling animation at any given point.
At the start point the marquee / roll value is 0% which means that no portion of the text is visible on this initial frame. When you scroll through the timeline, you will notice that the value of this field is increasing before reaching 100% at the final frame. This means that for the final frame the text scrolling has been completed and its last trailing character has been moved from view.
No matter how long the text value entered into the object is, the animation will complete within the specified time. However, this can result in text that moves at a rate that is unsuitable.
There is a dedicated "Progress" track for the marquee / roll object on the timeline. When the "Progress" parameter is animated, the corresponding keyframes are displayed on the "Progress" track.
The "Speed" value specifies the speed of the characters movement in pixels per frame.
If the "Use Speed" option is selected, the characters move with the speed defined in the "Speed" field, and the "Progress" parameter is ignored. This is a great way to be sure that text will move at a readable rate, although consideration of the overall display duration must now be given.
It is possible to make text scrolling follow a loop or ping-pong playback path. To do this, select the corresponding playback mode (Loop or Ping Pong) from the "Play Mode" drop-down list and specify the number of repetitions in the "LoopCount" field. To play the marquee / roll just one time, set the "Play Mode" to play once. These operations only have an effect when "Use Speed" option is selected.
"Free Run" feature relates to the scene loop. Let us consider its effect by an example.
Suppose you have a very long text for the marquee object. In order not to make a very long duration for the object, you can use the following trick: create a global loop at the end of the object duration and set it to loop infinite number of times.
As a result, the marquee text will play until the beginning of the loop, and if the "Free Run" option is enabled, the text will continue to slide continuously until stopped manually. If this option is not enabled, the text will constantly jump back to the position of the first loop frame, or in ping-pong mode run backwards.
Leave Loop on End
This option is useful when used together with "Free Run" feature.
When you use the previously described trick, with the "Leave loop on end" option enabled the marquee will leave the loop automatically as soon as its text ends and play until its end.
