360° Highlight Area 4D is in the Highlight category of Alex4D 360° Effects:
Here is what the Final Cut Pro 360° viewer and the viewer look like when the 360° Highlight Area 4D effect is applied:
The first set of parameters define how the border of the area is marked, using a coloured frame and shadow:
Frame Opacity, Frame Colour and Frame Thickness control the way the frame looks. Set Frame Opacity to 0% to turn it off.
Shadow Opacity, Shadow Colour, Shadow X offset, Shadow Y offset and Shadow Blur control the way the shadow looks. Set Shadow Opacity to 0% to turn it off.
The next parameters control the part of the clip inside the area:
Inside Opacity sets the opacity of the part of the clip inside the area.
Inside Scale can scale up or down the part of the clip inside the area.
Inside Blur can hide or stylize the area
Inside Pixellation can disguise or stylise the area
The next three parameters control the part of the clip outside the area:
Outside Opacity sets the opacity of the part of the clip outside the area.
Outside Blur can demphasize or stylize everything outside the area.
The Outside pop-up menu sets whether the area inside hides the outside area or not.
Background Fill and Background Colour add an area or colour behind the area selected. When 360° Highlight Area 4D is applied to a clip with transparency – such as a logo or a title – the area of colour covers the area outside the clip and all the clips under the clip the effect is applied to.
The last set of parameters define the area:
Area Centre, Area Size and Area Angle can also be set using the on-screen control.
Area Centre Limit stops the centre control from moving off the edge of the clip. Disable this if you want to keyframe this value so that the area can move off the edges of the clip.
Area Roundness controls the corners of the area. If Area Aspect Ratio is 1.0, a value of Area Roundness of 100 makes the area circular. A value of 0 makes the area sqaure.
Area Aspect Ratio defines the proportion of the width of the area to its height. 1 makes them equal. A value greater than 1 makes the area wider than it is tall. For example 2 makes the width twice the size of the height.
Area Feather controls the softness of the area edge.
