“Expand” Edges

[Kalleheikki Kannisto]

Grab a still image from some point where the paper is already torn but not all the way to the edges, and a still from the end state. Use former to extend the latter in Photoshop so you have an extended background still image. Drop this behind your footage and mask off with a feathered edge. You may want to add some animated noise to the output on the extended background layer if the difference between the video and the still is visible from lack of grain.

Mask out the scene as large as possible.

Duplicate the layer and use the RepeTile effect to expand the lower layer (mirroring might work, slide will work)

Hit ctrl(cmd)+alt+T to time-remap the lower layer and use a single keyframe for a freeze frame.

Or choose 2 keyframes and add in the expressionfield:

loopOut(“pingpong”);

Or a simpel:
loopOut();

Create a more smoother transition with the mask feathering of the upper layer combined with the mask expansion.

Perhaps I’m asking too much… Could you show it to me, please?
Maybe by my example on a new ae project… my work is the worst. ( Mark Doctor Method): https://youtu.be/a7UKmp9jNeo

Mainly it is a problem of “feather” of the edges, I can not do better.

I will see if i get some spare time to help out. I sugest to reshape the mask by using the pen tool and keep what you like (hole and flaps) and use a freez frame at the lower layer without the folds. Its a dynamic proces, you’r inventing while building it.

[Mark Doctor]

So i had to do a work around to counterzoom the shot, not having the original footage (thats the precomp)

Do a freeze frame on the first frame, which isn’t a clean plate. So i had to use the second frame, to show it can be done, tiled it and blurred it (Thats the lower layer)

Than reshape a regular mask with the pentool

WoW, I can’t get such a clean, homogeneous result!
Could I have that project to study it? (even if it’s not too much trouble)

Thank u so much and happy Christmas holidays to everyone!

[Mark Doctor]

I’m sorry I didnt kept the project.

Just freez the second frame, use RepTile and a fastblur. It will take less than five minutes to create.

[Gigi Marzo]

Thank u so much…

Could I put some irons in the fire here? If possible to add a picture -like a poster- on the “yellow paper” and simulate a realistic taer on wallpaper?
Do I make myself clear?

I’ll try to expose it better: we see the yellow paper with a draw on it (I will do it in photoshop), she comes in slashing paper with that draw, look like authentic, almost as if I recorded it from life…
