ABSTRACT
Finally, the Echo Operator property controls how the echoes blend together. Remember that we’re dealing with transparency here, so if we want to combine multiple frames-at least with this video-then we’ll need to use a blend mode of some type. And that’s what the Echo Operator allows us to do. Most of the modes, such as Add, Screen, and Maximum, will return a much lighter result. These are great for creating ghost-like effects or other soft, ethereal, angelic effects. We’ve been using Minimum as it returns a dark result which works well with this footage that has a lot of blown out highlights.
