|
* @short_description: An effect in a #GESLayer
|
|
*
|
|
* #GESBaseEffectClip-s are clips whose core elements are
|
|
* #GESBaseEffect-s.
|
|
*
|
|
* ## Effects
|
|
*
|
|
* #GESBaseEffectClip-s can have **additional** #GESBaseEffect-s added as
|
|
* non-core elements. These additional effects are applied to the output
|
|
* of the core effects of the clip that they share a #GESTrack with. See
|
|
* #GESClip for how to add and move these effects from the clip.
|
|
*
|
|
* Note that you cannot add time effects to #GESBaseEffectClip, neither
|
|
* as core children, nor as additional effects.
|
|
