Color control

Media objects, such as picture, video, live video or text objects allow keyframe control for dynamic color changes of the corresponding image information on the screen. Color control can be used for the following applications:

 

Producing control track and keyframes

For control via keyframes you need to add a control track to an object which allows setting of keyframes. Key frames are actually markers containing values for image manipulation. In our case this is a color used for image filtering. The area between two keyframes contains consecutive in-between values which become visible as continuous color change.

 

And this is how it is done:

  1. Right-click the object whose picture or video is to be controlled and select Control tracks. In the dialog box popping up, place a checkmark next to Color (Red, Green, Blue) and click OK.

  2. Double-click the control track to set a keyframe.

  3. If the screen is not open, open it now by pressing F10. Right-click the keyframe and select Properties.

  4. In the Properties Dialog you will find fields for numeric entry of color values for Red, Green and Blue, as well as a field which displays the resulting filter color. By default it is white, i.e. without color manipulation, which is 255 in accordance with RGB values.

  5. For color selection click the color field, which presumably will still be white. The following dialog will make color spaces RGB and HSB available for color selection.

  6. Grab one of the small squares in the corners with the mouse and drag it to choose the corresponding color. If you want to correct an image, the HSB color space is the better choice. But, actually, this is a matter of opinion. The effect is immediately visible in the screen window. Once you have found the corresponding setting, click OK.

The color white can be changed into any other color by applying filters. Therefore, you should design image elements (arrows, writing, etc.) in the image file in white and then set the corresponding color by applying this function at a later time.

  1. The filter color will now be visible in the color field. Click OK. If the selected color is to be transferred to the entire object click . If the values are to be transferred only to the beginning or the end of the object click   or .

  2. For dynamic and time-dependent color changes, add another keyframe (e.g. in the last third of the object) and enter a different screen field size and position.

  3. When the object is played, the colors will change in accordance with the keyframes. Possibly, the standard settings will still apply to the beginning and the end of the picture. In order to solve this problem you can copy the values of the adjacent keyframe and paste them into start and end frame.
