Enter-exit page loop transition

flaviotti wrote on 12/9/2015, 6:54 AM

Hi,

I am not a big fan of transition in general, but in my current project I am required to have few inserts introduced by a pageloop, and exited with the same transition (better if mirrored).
Would anyone have any suggestion how to implement an exit pageloop which will animate the exit of the "A" screen, with "B" underneath, instead of the usual "A" in background and "B" entering in animated page loop?

Thank you in advance,
/Flavio

You can keyframe the transition. Set a keyframe representing the end state at the first frame, and a keyframe representing the beginning state at the last frame. This will effectively run the transition in reverse, which by happy coinkidink will also mirror it.

thanks. the problem is that it seems to be always animating the coming screen, and not the current one.
Visually, what I am trying to implement is something like this:

video track1: .................A-IN <overlay clip> A-OUT...................
video track2: <main clip>.........................................<main clips>

where the dots are just there to place the text in alignment.

When I add the transition at the end of the inserted clip, the loop animate the introduction of the new clip. I would need to animate the exit of the current clip, as the new one is actually sitting there already, and the current one is leaving.
I hope I am explaining this not too confusingly.

hi again,

maybe I found a workaround, and it was inspired from your tip, so thanks again for having pointed me to the a possible solution.

I worked around it by doing the following:
* added a video track on top of the two listed before, which here I will call track-0
* Introduce the insert-clip with the normal page loop animation in track-1
* at the end of insert-clip, copy the portion that would overlap to the main clip in track-0
* add the transition page loop as usual, in the clip portion in track-0, with the same parameter, and leave the main clip in track-2 in their normal sequence.
* right click on the transition and display the transition progress envelope and reverse it.

This way the page which was lopped in, will loop-out revealing the main clip as if the where momentarily covered by that info-page.

I hope I expressed it clear enough. But any other tip is always welcome, if it introduce some elegance in the way I am managing tracks.

Cheers!

Flavio, see if this helps.
Once you apply the FX to the transition, right click on it and select Insert/Remove Envelope - Transition Progress. Once you do that, you'll see a transition curve that goes from bottom left to upper right. Click on the beginning point (at the bottom) and drag it to the top. Repeat with the end point but drag it to the bottom.
Is this what you're looking for?

Flavio, glad I could help. I read Kelly's (Chienworks) suggestion and was puzzled at first. Then I started playing with the different options and stumbled across that one. I've never used it before so it may be of some help to me someday too :)

@Mike

Your little discovery will be of great value to me. I do a lot of map animations using the gradient wipe transition and a problem has often been that parts of the movement should be faster or slower. I resorted to rendering the track using alpha and then applying a velocity envelope. This will definitely be a lot easier and faster.
