Dear AE expressionators,
Concrete: I am making a template whereas the user can change the text font and that it will automatically update this to the hole template.
For example, see the picture.
So everything I change in the above text layer the under text layer transforms with it. But if I change the font it doesn't.
Does after effects use a different expression for automatically changing a font?
I would really appreciate your help!!!
I'm using after effects CS6
"3D warp" as seen on tv.adobe "What's New", does not seem to be available on my version of CS6 AE (from disk). I'm not getting the geometry option even though,I have the 3D box checked and it is a pixel based layer. I do get the other expression options such as transform and material options. Can anyone help me bend stuff?
I was wondering if it's possible to create a stop/smooth ending to a LoopOut expression on Rotation and Position keyframes. I am currently using OSX 10.9.3 After Effects CS6 and I have tried a couple of things that haven't worked for me.
adding a checkbox expression control to the layer and an expression for loopOut()
if (effect("Checkbox Control")("Checkbox")==true){
loopOut();
}else{
value;
}
loopOutDuration(“cycle”,2)
Unfortunately neither of these seems to work. I was wondering if someone had a solution they have come across.
Thanks very much
Ira
Hello,
I have a fairly complex set of expressions on multiple layers. These layers together make up an overall effect for a piece of footage. For convenience I have these expression linked to a controller null object so I can control them from one place. Now that I have it set up, I want to duplicate the group of layers (footage item, various effects, and null object controller) multiple times. I basically have a template for a footage effect that I want to duplicate multiple times so I end up with many pieces of footage with this effect applied. When I duplicate the group of layers, I'd love to set it up in a way that the expression variables will now point to the duplicated controller object. I noticed this behavior happens if the expression is a simple pick whip from one property to another. Basically a direct connection. But if I attempt to store this pick whip selection in a variable to be manipulated further, this functionality ceases. So my question is, how can I create a set up that will permit me to duplicate layers and have the expressions update as if they were a simple direct pick whip from one property to another? Is this possible? If not, how can I better set this up to allow me to accomplish my end result?
Thanks!

When I turn on some file at first, it suddenly appear that comment, which said 'In this project, it has expression error 1/1 error'
Actually, I'm a learner of After Effect so I do not know fluently what's what.
Here is the expression having error.
transComplete = effect("Slide Master Control")("Transition Completion");
if (effect("Slide Master Control")("reverse direction") == true)
{xPos = linear(transComplete, 0, 100, thisLayer.width, 0)}
else
{xPos = linear(transComplete, 0, 100, -thisLayer.width, 0)};
[xPos, 0]
Thank you.
If you want to email me, please send me into 'triumphalboy@gmail.com'.
I can send you this aep file for you in order to fix the problem.
Hi,
I'm making a video with a character and a speech bubble, the text is animate with a typewritting effect, I was the one asking for an expression to always stop the animation 2 second before the end of the sentence but I didn't take my main adobe account.
Anyway, the bubble have a delimitation so the text boxe fit inside the speech bubble some sentence fit inside and some are so long that we cant see all the sentence.
When i put an auto-scrolling effect the text animation go out of the speech bubble.
I'm looking for an expression that can scroll up the top text ligne to make appear the next ligne on the buttom.
My english is pretty bad but the best example is show in this video of pokemon emerald, when the professor talk and explain the game Pokemon Emerald: Game Intro + Prof Birch Intro To Pokemon - YouTube at 1:52 its exactly the type of animation I'm looking for.
Thank you!
Hi there,
Is there a way to put a limit on value range when linking it to key-framed audio?
My situation is that I want to link the Glow Intensity of one of my objects to the key-framed audio. The issue I'm having is that everything north of 0.4 looks horrific.
So was wondering if there was anything I could add to the expression that will only allow the value of the Glow Intensity to vary between 0.0 and 0.4?
Cheers
Simon
I've seen linking to text documents with code snippets in it.
So that means the external text document must contain bits of scripting.
I would like to link to txt documents (or csv) that do not contain code.
Total noob users must be able to link a text to a After Effects project.
I have a website data catcher which exports CSV values.
It would be ideal if After Effects can hoover up the text and put certain pieces into certain source texts.
We're talking automated sports cards here.
Is this possible without adding code to a text dump?
Or is this just impossible?
I'm new to After Express and just diving in to expressions. I was trying to figure out if there was a simple way to use the wiggle expression in a way that it would wiggle individual characters in a text block independently of each other.
Definitely appreciate any help.
Hello,
I am making a news ticker and I am happy with the design result so far. The only thing what's left is repeating the ticker.
This is my current setup:
loopOut("cycle", 0)And 2 keyframes. One at the beginning and one at the end. **offset = 8.34; // Value in pixels per frame x = timeToFrames() * offset; value - [x, 0]
** I am looking for a solution to let it loop seamlessly. So the first news items should connect to the last news item and so on..
Do I need a separate expression for this? Or is there any other trick to accomplish this?
Now that "copy with relative property links" is available, in what case would you find using just "copy with property links" beneficial. Wouldn't the relative copy work just the same in all cases?
Let's say there is a Comp1 with a pretty complicated animation that involves a text layer. CompMain is the main comp with 10 instances of Comp1. Each instance has different text, position and timing. Can I set the Comp1 text layer Source Text from an expression in CompMain? If this is not possible, is there any workaround? Otherwise, the alternative would be to have 10 versions of Comp1 with different text and that would be too messy.
Hi!
trying to do the simple task of separating 6 characters (numbers) and adding a space after the first 3.
My script reads:
siffror = parseFloat(Math.round(thisComp.layer("Räknare Slider").effect("Slider Control")("Slider")));
s1 = siffror.substring(0, 3);
s2 = siffror.substring(3, 6);
"Co2 saved: " + s1 + " " + s2 + " ton";
it says siffror.substring is not a function.
What am I doing wrong here?
Hi,
I just wrote a series of expressions linking two text layers together along with controls on a null object, I'm trying to save it as an animation preset so that I can quickly reuse it in the future, however when I select my layers and go to 'Animation', 'Save Animation Preset', the option is greyed out.
Am I using the correct method?
Thanks
Hey there have been looking around the net, does anybody have any pointers re: AE fixing the issue of expressions resolving to "?" when they encounter a special character? I thought Adobe had announced that they had fixed that... ?
Thanks.
I need an expression that would automatically change the font size based on how many characters are typed in.
The goal is to fit multi-line text into a bounding box as it's read from the external text file.
Does anyone know whether it's possible through an expression, or SDK by writing a plugin? So far I was unable to find any info on this topic.
Thanks for any ideas.
Greetings community,
i found an expression that makes a floating animation with consistant oscillations.
xAmp = 3; //height of undulations (pixels)
xFreq = .3; //undulations per second
xSpeed = 150; //speed of wave (pixels per second)
wl = xSpeed/xFreq; //wavelength (pixels)
phaseOffset = ((position[0]%wl)/wl)*2*Math.PI;
y = xAmp*Math.sin(2*Math.PI*xFreq*time + phaseOffset);
value + [0,y]
This expression does the oscillations only on the Y axes.
My question:
Is there a way to make the expression do the oscillation not just on Y, but also on the X axes at the same time?
Hey guys,
So, I'm trying to assign the X value a null object had at the previous frame so I can continue to subtract a number from it cumulatively. I'm trying to assign it to a variable (prevframe). I'm not sure where I'm going wrong, but the line I'm trying to do it on is written as follows:
prevframe = transform.xPosition.valueAtTime(time-(1/24))
So in my mind, this should be taking a look at the value of X on the null, then looking back in time to figure out what it's value was on the previous frame (my frame rate is 24, so I'm dividing 1 second in to 24 pieces and telling it to subtract that much from the current time), and assigning whatever that returns to the variable. But it's just returning a static value, even though I'm subtracting from it. I feel like it's not the correct syntax, but I really have no idea.
I want to continue to subtract a value which is based on the velocity of another object from this, which I have worked out, I just can't figure out how to reference what this nulls X position was in the previous frame so it always returns the same value until all motion has stopped. The formula the variable is being run through looks like:
finalposition = prevframe - camvelocity
Which is then assigned to the final X position of the null object.
So, I'm not sure where I'm going wrong. I hope I've provided enough information to help someone wrap their head around this and hopefully help me solve it.
Thanks in advance,
-Seth
I am definitely a beginner when it comes to expressions.
I am currently using a "bounce" expression on the position parameter of some objects as they come on screen. However, the next time they change positions, I don't want them to bounce. Every time a motion tween ends in a static position, the position expression gets applied and the stuff is moving around.
I'd like to be able to keyframe the expression so that it worked only when on the keyframes that it makes sense to affect.
amp = .05;
freq = 1;
decay = 7;
n = 0;
if (numKeys > 0)
{
n = nearestKey(time).index;
if (key(n).time > time)
{
n--;
}
}
if (n == 0)
{
t = 0;
}
else
{
t = time - key(n).time;
}
if (n > 0)
{
v = velocityAtTime(key(n).time - thisComp.frameDuration/10);
value + v*amp*Math.sin(freq*t*2*Math.PI)/Math.exp(decay*t);
}
else
{
value
}
I got this script from somewhere online. The only thing I know how to manipulate are the initial values of amp, freq, and decay.
Hi,
when I apply an expression it starts from the beginning of the composition, but if I want to start it, for example, after 10 seconds, how can I?
Sorry for my english.
