Rendering menu > Video Post > Video Post window >
Select a filter from the Video Post Queue. > Video Post
toolbar > Edit Current Event
When a Filter Event is selected in the queue, the
Edit Current Event button opens the Edit Filter
Event dialog to provide image processing for
images and scenes. Several kinds of filters are
provided, see list below. For example, the Negative
filter inverts the colors of an image and the Fade
filter fades an image in or out over t ime.
An Image Filter event is usually a parent event with
a single child (which can itself be a parent w ith
children), for example, a Scene event, an Image
Input event, a Layer event that contains Scene or
Image Input events, or a Filter event that contains
Scene or Image Input events. You can also add
an Image Filter without a child event, in which
case the Image Filter processes the result of the
prev ious events in the queue.
