Live effects > Chroma key

Chroma key effect

You can find the chroma key effect in the Toolbox of AquaSoft SlideShow under the tab objects in the live effects field.

Hint

This feature is only available in AquaSoft Stages.

1. Action of the chroma key effect

After you have inserted an object into the chroma key effect, you can choose the color your would like to be transparent in this object. For example you may have recorded a video against a green background. This background can be removed in the chroma key effect or replaced by a different background.

The effect can unfortunately not perform miracles, but is heavily dependent on video material. The smoother the background and the more clearly it is differentiated from the foreground, the better it can be removed by the effect.

2. Application of the chroma key effect

Chroma Key effect in a chapter in the timeline

Drag a chapter object from the Toolbox into the Timeline. In the first track, insert the background that is to be visibly displayed in place of the color which has been selected in the chroma key effect.

Drag the chroma key effect into the chapter's second track. Now, into the chroma key effect insert an image or a video.

3. Settings for the chroma key effect

Settings for chroma key effect

In the properties field you can set the following options for the chroma key effect:

•Name - for a better overview in the Timeline, you can give the effect-container its own name.

•Tolerance- specifies how far the color can deviate from the selected color-key.

•Transition- specifies how hard or soft the transition from color-key to no color-key may be.

•Color-key - selects, using the pipette, the color that should be transparent.

•Maintain shadows - shadows that lie on the color of the color-key are shown as dark.

•Invert- everything will be transparent, except fo the area with the selected color.

4. Choosing and customizing a color

Selecting a color for the color-key

To choose a color for the color-key click on green, which is already preset. Now the color selector appears.
Click on the pipette symbol, in order to choose the color which will be transparent directly out of your video or image. Hold the dropper to the best on the thumbnails in the Timeline.

Using the two controllers, tolerance and transition you can now set the transition or the permissible deviation of the color. Here a bit of tact is needed and a clever combination of the two settings that should be adjusted appropriately depending on the initial setting.
