I am new so go easy . I purchased a Sequence from a well known vendor and the faces in the sequence fade in and out very nicely. on the "FACES" Effect there is a green and red line above the face icon .... Is this some sort of preset. I would love to figure out how to do that. Thank you all
You may have closed the window off.
You can re-open it under View > Windows > Layer blending (adds a tick to say it's open).
Or, Click reset to default.
