Hello,
I have created a layer on the timeline.
I put an image there, and do :
Insert -> timeline effect -> Transaction/Transition - > Transition,
unchecked the wipe check box, and checked the fade check box,
direction = out.
When click update preview, I see that my image is faded out - That's OK.

When I do : press <f6> after the last key frame +
Doing the same thing as the first time,

I get no result as expected : my image is not faded out as expected.

Why ?
How should I solve this problem ?

Thanks :)
