HI
Where did you find Fade which refers to frame numbers please? I haven't noticed this before.
Fade is usually applied at a split or at a clip start or end and is controlled by duration.
Fade in by clicking the "f" on the timeline clip thumbnail and then entering how long you require the fade in to last.
Fade out by clicking the transition sign at the end of a clip, select Fade and enter the duration etc.
You can also Fade in and out using the Transparency effect. at any point between start and finish.
I haven't seen frame numbers...:-)
