Hi guys, it's VIN with Boris effects and in this tutorial
I'm going to show you how to use torna pin studio to quickly and easily pin textual wall inside of After Effects
Ok, so here we are in AE and I have my original footage of this young woman walking down an alleyway
I wanted to use this footage because not only does it have a nice defined wall for us to attach text to but she moves
In front of it, so we'll get some quick masking tips to really help sell this effect
I've also added some 80 text to the top track that we're gonna use as our insert to do this
Let's head to the match move category and drag
BCC corner pin studio right on to our background track
The first thing I want to do is change the workflow to apply to background
it's important that we select this particular workflow because it's going to allow us to pull the background layer into
mocha in a moment to do this
I'll set my foreground insert layer to my titles and then enable composite background now when I do this
I'm going to see two instances of the text
The first is the corner pin text and the second is the main text track since we don't need to see the text track
Let's just disable the track visibility and there you go with the correct workflow selected
I'm gonna go to my mocha motion tracker and launch my custom UI
inside of mocha
I have my two tracker elements my search area and my corner pin guide
Now this box represents each of the four points of my corner pin
Now your first thought may be to keep the search area and the corner pin connected after all we want the corner pin to match
The movement of our motion tracker, but here's the thing mocha is a planar tracker
So it's tracking all the pixels within our search area
This is going to become a problem if we want our text on the wall because as soon as she passes in front of it
Mocha will lose the track. So what do we do?
Well, as I said mocha is a planar tracker
Which means that as long as we track something along the same plane as our corner pin
We'll get the results we want and as luck would have it. There's a window up here along the same plane as the wall
I want to apply my text too. So I'll set my search area to track the movement of this window my corner pin
I'm gonna place against the wall
now I can turn on the grid to make sure it lines up nice and evenly
tweaking it as necessary when done I'll hit track and
There you go
When satisfied hit apply and our text has been tracked to the wall
I can open up my transforms control to make adjustments to the scale and translation
It's a lot easier to fine-tune the position this way because regardless of any changes I make it's going to maintain our motion tracking
When satisfied I can play that back and that's looking pretty great
Now what we want to do now is mask out the text as she walks in front of this to do this
I'm going to go down to mocha pixel chooser
Now make special note that this is not the mocha motion tracker that we just used
In fact, I'm going to close that group since we're done with it
Mocha pixel chooser. We'll use the same power of mocha tracking but allow me to mask out part of the effect
Now how detailed you want to get will naturally?
Depend on the effect you want to achieve you can go in and create roto masks for her arms head body and track them individually
But for this tutorial, I'm just gonna create a quick garbage mask that more or less follows our woman to do this
I'm gonna select my brush tool and quickly draw a shape that matches her body
When done I'll click the arrow and create a mask next
I'll track forward keeping an eye on the movement of her arms and pausing ever so often to adjust the mask
While mocha will not display the composited text. I do know that it's in this area
So I'm gonna make sure that anytime she's positioned here. I keep the mask as tight to her as I can
I'll pause the track select some points and manually adjust
and I'll just continue to do that until she's passed the sign when satisfied I'll hit apply and
My text disappeared. Why did this happen? Well, we just told mocha that the effect is in this area
What I need to do is click invert mask here in the pixel chooser mask group and that will invert the effect
Masking out the text only when she's in front of it if I need to make any adjustments
I can always jump back into mocha and tweak that mask
But essentially that's pretty much it
All that's left is to make a few final tweaks to really sell the effect
And the great thing is that corner pen studio makes it very easy to do all that within the effect itself
First I'm going to come down and feather my mocha mask. I'm talking ever so slightly maybe a pixel or two
Anymore and you'll draw attention to the masking and the effect will look very weird
Next let's enable light wrap
This will reflect the luma from the background layer onto our foreground layer
Just nudge that up a bit to soften the edges of the text making it look like it's part of the scene don't do too
Much or to look feathered
Lastly these titles really stick out like a sore thumb
I want to make them look like that part of the wall to do that
I'm going to open up the composite group and change the apply mode to overlay
When I play that back
We have quickly and easily added text to a wall within the scene
and while I did this with text
You can absolutely use a still image or other object using the exact same steps now since these are titles
I can always enable drop shadow if I want them to pop off that surface
But as far as creating this effect inside of After Effects, that's all there is to it
