The Echo allows you to use existing content in the project in several places within Timeline. To mirror content with the Echo object, it is placed in a Flexi-Collage object. Such a Flexi-Collage marked as a "source" can then be automatically recognized by the Echo object, and targeted referencing by name at the Flexi-Collage is also possible.
 
Working with Echo objects favors a streamlined and more efficient structure in the project, as content that is to be used or shown several times no longer needs to be copied.

To be able to use the echo object, you always need a simultaneously running echo source. A correspondingly marked Flexi-Collage serves as the echo source. The Flexi-Collage can simply contain images or videos, but also complex collages, animations or (mask) effects.

All Flexi-Collagen can be used as an echo source. To make an Flexi-Collage available as a source, check the Echo source box in the Properties of the Flexi-Collage. The Flexi-Collage can then be "seen" by the Echo object.

Also decide whether the Echo source itself should also be displayed.

To clearly identify the Flexi-Collage, it can be given a name. A unique reference to this source can then be made on the Echo object. This is recommended if several Flexi-Collagen are available at Echo runtime.

Use the selection for the source to specify from which Flexi-Collage the echo should play the content and, if necessary, modify it with other effects available on the Echo.
 
Flexi-Collages are listed as a source if they are marked as a source.

- Available, simultaneously played back Flexi-Collage: The source is automatically the Flexi-Collage that is closest to the Echo object in a track above it.

- Simultaneously reproduced Flexi-Collage "Name": Source selectable via the name of Flexi-Collage.

- Plugin host: for playing external content

The echo object can be provided with live and object effects as well as transitions and can be placed and animated as required in the Layout designer. The other properties of the echo object correspond to those of the Flexi-Collage object.

1. Insert a Flexi-Collage object into the Timeline and insert a video. Mark the Flexi-Collage as an echo source in the Properties and leave the checkmark next to Show source.

2. Drag an Echo object from Toolbox to Timeline below the Flexi-Collage. In the Properties, set Available, simultaneously played Flexi-Collage as the source. Adjust the duration of the echo to the duration of the Flexi-Collage.
 
3. Copy the echo object several times to have a total of four echo objects.

4. Place the four echoes one below the other in the layout effect. In the properties of the layout effect, set the layout to Horizontal grid. Lower the margin and space to 0%. At Flexi-Collage, deactivate the Show source checkbox .

(In principle, you can also use just three echo objects and include the Flexi-Collage in the layout effect. The variant with the four echoes was chosen here for greater clarity. Depending on the effect and your own discretion, decide whether the source should be displayed or not).

5. Drag the LUT effect (or other color effects) onto an echo object and select different settings for the effect.
