Reverse Scale Expression

In the Demon Face Warp Tutorial we learned to reverse track by adding expressions. One expression reversed the rotation by multiplying it by -1.

Now I had a question about reverse scaling… I didn’t know, until now:

Basically you create a variable inside the final comp where you apply the reverse rotation expression but instead we alt click on the scale and write
m=100/comp(“yourPreComp”).layer(“originalLayer”.transform.scale[0];
value*m

So if m=400%, then 100/400=.25, and .25*100% is 25%. And 25% of the now 400 percent image is now back to the original size.
To create the layer variable, you can pickwhip the scale of the precomposed layer as shown in the tutorial. Then add [0] so that you only use one of the scale values for the width.

Try it out and hopefully you can use it in the future.

EDIT for Clarification: When you motion stabilizing something with 2 points you can calculate the rotation and scale from the Motion Tracking Menu, this scales up or down as needed to keep the 2 points the exact distance appart. Thanks for bringing this up Kyle, I’m tired too.

Hey, guys.

Maybe the great Andrew has no time to answer us so i find the solution myself and pass it to you:

s =100/comp(yourPreComp).layer(originalLayer).transform.scale[0];
[s,s]*100

obviously you have to change yourPreComp and originalLayer with Comp name and Layer name of your footage or simply write this expression in your scale parameter, select this "comp(yourPreComp).layer(originalLayer).transform.scale" and Pickwhip the scale in yourPreComp.

Simply

It works on CS5.

I'm still stuck on that expression (yeah I'm a bit late, sorry). My brain is actually exacuating steam through my ears... I fear the overrun shortly.

Please can someone help me by explaining how to reverse a scale tracking? That would be amazing.

I am little confused about the scale expression. Is it even needed if you check the scale box as well as the position and rotation boxes and reverse scale it, or does it have to be checked along with the expression? Do you have to pickwhip it first and then add the rest of the expression?

An update on my travails w/r/t reduced resolution as a result of reverse scaling...

I thought I finally had it cracked when I discovered that I could restore my original resolution by selecting 'Collapse Transformations' on the precomp's Layer Switches. However... whilst this seems to retain the tracking data for, I suppose, MOST purposes, it just doesn't seem to work in conjunction with the Liquifier effect.

I can happily add in sunglasses, tinfoil hats -- stick a parrot onto my subject's shoulder, and give her an eyepatch and a wooden leg -- and as long as those layers are parented to the precomp they will follow the tracking data perfectly! But as soon as I try to apply the Liquifier with the 'Transformations Collapsed' switch selected (thus restoring my original resolution), this effect will not follow the tracking data at all...

I have also tried selecting 'Preserve resolution when nested' from the Advanced Compositions Settings window -- no luck there either...

Any suggestions? Andrew? Anyone?

Could it perhaps be that the (reverse scale) expression needs to be modified so that it uses as its source the entire original COMP (and all of its info and properties), as opposed to just the one layer? If this sounds stupid, bear in mind that when typing expressions, I feel as though I'm reading aloud from a foreign-language phrasebook, rather than speaking a language that I actually understand ("My hovercraft is full of eels...")

I hope I haven't scared everyone away from this thread... Surely I'm not the ONLY person who's been staring at their computers all weekend!

Cheers...

Hi everyone...

I'm new to this site and new to After Effects -- but I always find the best way to learn a new program is to dive in at the deep end and pick up the basics along the way...

So I managed to perform a successful facial warp on some footage that didn't require scale adjustment. Having done so, I was then keen to try it out again on some footage that would. I managed to get the expression at the top of this page to work (see below for a couple of forehead-slappingly obvious tips that could explain where Yann and others might have gone wrong), but I've now run into another problem...

The subject in my footage moves towards camera all the way from a full-body shot, right into a medium close-up, where she remains for the duration (and the majority) of the clip. So, when I track and stabilize the scale (along with the other properties) and preview the result, I have my image swiftly shrink into a tiny little window--bobbing about in the blackness--as my subject approaches camera. So then when we precomp this and reverse the scale, we're having to zoom in on the image somewhere around 750% to compensate! Obviously, the result is a very lo-res, pixelated--completely unusable--image, whereas on the original footage we had a nice, high-res medium close-up.

Can anyone tell me where I might be going wrong? Is there anything I can adjust within the comp settings? Are there any hidden properties one can adjust when creating the precomp in the first place that might fix this? Is it possible to track the scale separately from the position and rotation, and apply it to an adjustment layer or something, and still have all the amazing flexibilty that this overall technique offers?

Any help would be greatly appreciated...

And as for those those tips that could explain why some people might be having trouble getting the expression to work...

1. It seems that Andrew accidentally forgot to close the parenthesis after "original layer", so if you're copying and pasting the text from this page, make sure to put that in.

2. When typing the name of your original layer, don't forget to include its extension as well.

Hope this helps... Cheers...

Wow. It's so funny, because I had to use reverse stabilization at work to cover something up on a piece of video. I had to use all three (position, rotation, and scale) and it took me a while, but I figured out an expression for the scale so it would reverse as well. But mine was long and complicated. Not as simple as this one you put up. I should just keep your site embedded as my background and I can just look over every couple of minutes to see what wonderful new toy you've given us.

Hi there, 1st, thanks Andrew for all these great tuts, I was basically editing a footage using the "reverse stuff" and found out I had to track the scale too...
How to reverse the expression? hopefully you were there... but.... I sorry, I have tried it either way, AE won't let me use the expression:
m=100/comp(”yourPreComp”).layer(”originalLayer”.transform.scale[0];
value*m

so I may look dumb, but is that just what we're supposed to write (replacing the layer name of course?)
otherwise you just say to pickwip the scale expression in the precomp layer and add 0... still nothing changes....
Help I going crasy....

G'day Andrew,

Thanks for annother excellent tutorial. and thanks to Kyle for asking about motion tracking on the 'z' axis. I'd be very interested in seeing a tutorial about motion tracking a subjuct where zoom or distance to and from the camera is a consideration... My question was actually to do with the programming language that you actually type in to achieve the reverse motion tracking. Can most of the effects and plugins applied be viewed in this way? as in programming lingo that can be edited?

the plug in for Premiere is free, but the songs cost. You get 10 free tracks with it, and they sound like actual recordings of music. I use one I bought that was called Leap of Faith, which is their version of Van Halen's "Jump". I used it in a youth activities promo and all of us 20 somethings were singing along, and it was pretty cool.

Funny how the original face warp blog got 396 comments almost instantly, but here we're down to 78 comments after 4 days!

Maybe the overriding point of this blog is: This s**t ain't easy, you need to apply yourselves people, after all he's only your copilot!

I had my actor for my demonface test move his face towards he camera, and I couldn't think of how to make it look correct. I didn't think to reverse the scaling. I will have to go out now and tr it again. I wish I had some time to go and shoot a movie just for fun, maybe I will make my own zombie short, and all of my zombies will have demonfaces or something. Sounds like an excuse for some gratuitous blood, and nonsensical violence.

Nice effect though, i remember running into this problem when i tested out the demon face cause my original shot featured the subject moving their face forward as they pulled their scary expression. I ended up re-shooting and getting them to stay level. This technique should make for a much more generalizable effect over a diverse range of shots.

Yeah, sorry I should have mentioned that Kyle. When you motion track someone you can also motion track the scale. So if they come towards you or away from you, the tracking would shrink or grow you as needed. Also if the camera zooms in or out.

So with this expression you can reverse it but get the benifits demonstrated in the video.

Great Comment.

Sorry guys, that admin can be harsh ;)

wow. too many spelling mistakes.

CORRECTIONS: what would you use reverse scaling for? Life if the person was moving towards the camera or we zoomed into their face?
