About Video Cropping

Cropping allows you to create visually interesting viewports through which to show a video. The cropping area defines an area within the Media Screen. Any part of the video that lies outside of the Crop Shape area will be cropped off (not viewable).


Apply Crop

When the Apply Crop checkbox (Figure 1) is checked, the video will be cropped to the defined Crop Area. When unchecked, no cropping will be performed.


Apply Live button

When the Apply Live button (upper, right on Figure 1) is clicked, it will activate a connection to the loaded Media Screen (if one is currently loaded). When active, any changes to the Crop Area made with the Crop Area Tool will be reflected immediately on the loaded Media Screen.


Refresh on Media Screen Size Change

If you change the Media Screen Size, you will need to click the Refresh button on the Media Screen Dimensions control panel to force the cropping area to be recalculated.

Crop Shapes

Select a cropping shape via the Crop Shape selector (Figure 1) in the Crop Video controls section.

Available shapes: Parallelogram (leaning) Left, Parallelogram (leaning) Right, Diamond, Rectangle, Ellipse (or Circle).

Video Crop Area Tool

The Crop Area Tool (Figure 3a) let's you expand/contract the shape size and stretch it in horizontal or vertical directions to create custom cropping shapes. You can also relocate it's position within the Media Screen.

Open the tool, by clicking the Video Crop Area Tool button (Figure 1). Click on the Crop Shape and drag it to relocate its position. To resize it, click on the resize handle (red square at the bottom, right corner of the shape) and drag it. There is a wide variety of sizing and locating functions available on the tool bar.

Crop Examples

Here are a few examples of how cropping can be applied. In these examples, the Media Screen Background is set to orange to clearly demonstrate the effect. When the Background is set to match the Windows Desktop color, the orange area would be effectively invisible.
