For this purpose, there are several effects that may be appropriate.
Transform ( Effect, not the native one at the clip / Layer )=> Scale @ 0% makes the clip disappear. Then, play with the opacity slider to make the video appear / disappear.
Infinite Zoom => Playing with the Alpha cursor allows you to make the clip disappear / appear. In addition to this, the "Num Slice" slider allows you to add an effect similar to Exposure (between 2 and 4 slices). At the beginning of the sequence, this makes the clip more "powerful".
( All other settings are at Zero)
Other effects could be appropriate, but from my experiments, I only retained these two.
After several tests, I find the method with the Infinite Zoom effect better than the one with Transform.
