> Configuring Video Properties
> You can configure video properties to make visual changes to screen recordings, camera-based video, and other imported video clips, as well as image clips in a project.
> You can also add video actions (transitional properties—those which change over time) to a clip and apply video properties only to the action. Actions display as yellow rectangles inside the clip—they are time-limited sections of a clip which enable you to apply properties to that time-bound section of the clip. Video actions can be added to both the start and end of a clip to create a transition. For details, see Using Actions.
> Select a video, screen recording, or image clip, or place the scrubber at the start or end of a video action in a clip before applying properties. To display the Screen Recording Properties pane, click the Screen Recording Properties icon, as shown in Figure 44.
> Figure 44. Video Properties
> To reset all properties in the selected clip to default values, click the gear icon at the top-right corner of the panel and select Reset to Defaults.
> Video properties are described in Table 6.

> Table 6. Video Properties Pane
> Control | Description
> Scale | Use the slider or enter a value (0-400%) to change the scale of your image. This is useful for highlighting a particular portion of the screen, or in a video action to create a zoom effect.
> Position | Enter X and Y coordinates to specify the location (in pixels) of your video or image on the canvas, based on the center of the image. You can also reposition the image by dragging the image on the canvas, or nudging the selected image with the arrow keys.
> X/Y/Z Rotation | Use the rotation options to rotate (in degrees: -180 to180) the image in a virtual, three-dimensional space. X rotates the image along a horizontal axis. Y rotates the image along a vertical axis. Z spins the image along a depth axis. Or, use the thumb wheels to rotate the image in real time.
> Opacity | Use the slider to set the opacity value or enter it manually (0 to 100%). The greater the value, the more opaque the image. When set to zero, the image is transparent—invisible. This can be used with a video action to fade an image in or out, or if you have a video voice-over, and would like to periodically display your entire camera recording frame.
> Cropping | Click the disclosure triangle down to display cropping options. Set the crop margins (by pixel) for left, right, bottom, and top.
> Reflection | Check to implement reflection. Use the slider to set the value or enter it manually (0 to 100%). Reflection creates a mirror image of the selected clip below the clip itself. The greater the value, the more opaque the reflection. When set to zero, the reflection is invisible.
> Corner | Drag slider to adjust the roundness of the corners.
> Shadow | Check to create a shadow effect behind a still image. If the image uses a transparency, the shadow only reflects the non-transparent part of your image. Use the thumb wheel (or enter the value manually) to set the angle of the shadow relative to the image in degrees (-180 to 80 degrees). The default is -45 degrees. When checked, configure these options:
> Color | Click the color field to select the shadow color from the color picker. Default: black.
> Offset | Use the slider to set the value (in pixels) or enter it manually (0 to 150 pixels) to specify the distance between the shadow and the clip. Default: 40.
> Opacity | Use the arrows to set the value or enter it manually (0 to 100%). The greater the value, the more opaque the shadow. If the value is set to zero, the shadow is invisible. Default: 75%.
> Blur Size | Use the arrows to set the value or enter it manually. Blur is a gradual loss in opacity as the shadow spreads from the center. Default: 4. Range: 0 to 100 pixels.
> Color Controls | Click the disclosure triangle down to display color options.
> Saturation | Use the slider to set the value or enter it manually (0 to 400%). Saturation is the intensity of a color relative to its brightness, represented as a percentage. Default: 100%.
> Brightness | Use the slider to set the value or enter it manually (0 to 400%). Brightness is the degree of luminosity present in the image, represented as a percentage. Default: 100%.
> Contrast | Use the slider to set the value or enter it manually (0 to 400%). Contrast is the relative intensity of the black and white values in an image. A high contrast has a greater intensity of black and white values. This value is represented as a percentage. Default: 100%.
> Video Filters | Click the plus icon to add filters to the selected clip. For details see Using Audio and Video Filters.
> Add Video Action | Click to add a video action at the moment indicated by the scrubber in the selected clip. You can also click the +Action icon at the top of the panel.
