• Positional key and Wiggle expression images

  Hi, let explain me my problem;

  I have a px 5000 x 5000. PNG that I want to show a little at a time in a1920x1080 comp.

  The .png layer moves to the left of x-amount holds it is the position, then left again once, holds, then moves diagonally to the left and down. The movement rehearsals until the entire .png was reveal a piece at a time. It is supposed to mimic the movement of eyes scanning left-left-down and left-etc. during playback of a graphic novel. The 'hold' is eyes absorbing the information as part of comics before sweeping left.

  This bit is fine. But I want to add a wiggle expression to imitate the random, somewhat unstable movements of the eyes and body (think 'pocket' aesthetic in the movies).

  How can I add the wiggle when I already have positions in place keyframes?

  I tried the precomposition layer and adding the wiggle to the original layer and precomp' but none worked.

  Thank you

  Karl

  Wiggle additively proceeds by what the current property value is, so it is not serious if there are keyframes or not. Simply apply it to the real moving image. The rest is up to your real settings, but since you have not provided to them, we can tell you what may be wrong.

• I can animate individual characters in a block of text using the Wiggle Expression?

  I'm new to after Express and just diving in expressions. I was trying to understand if there was a simple way to use the wiggle expression so that he would wiggle of the individual characters in a text block independently of each other.

  Certainly appreciate any help.

  Have you tried the earthquake selector? Alternatively, you could add a selector expressions and add and raise the expression as follows:

  seedRandom (textIndex, true);

  Wiggle (1,100)

• AE CC 2014 - Wiggle Expression do not assign values similar to the scale

  So I just noticed that the wiggle expression no longer works how it is used for. I found an article, explaining the changes in the algorithm of noise used for expression wiggle what is new and changed in the 2014 update after effects CC |  After the effects of interest area and speaks of the ""fixed a bug in the implementation of the Perlin noise algorithm "section. "

  I don't know if that is what is at the origin of the problem, but let me explain.

  I'm just add a wiggle on the scale of the object expression.

  Wiggle (5.50);

  That would normally scale settings of the object with the same value. It would be so (100 100) to (125 125) and so on.

  Now however with CC2014 expression is the allocation of the different values for each value so get (125, 115) or something even if the button "constrain proportions" is activated.

  So I tried to cheat it:

  Temp = Wiggle (5.50);

  [temp [0], temp [1]];

  Again you have different values, even if I insert the same variable?

  Temp = Wiggle (5.50);

  Temp;

  Always had different values... I do not understand someone can help?

  Try this. Add a slider control of expression to the layer with the following expression:

  Wiggle (5: 50)

  Then add this expression to your scale property:

  w = value [0] + effect ("Slider Control") ("Slider");

  [w]

  The problem exists because wiggle will act on all of the values in the table of the property you have selected independently. It was therefore put up something with a single value as a slider control of expression.

• If is it possible to apply the wiggle expression loop to individual characters in a block of text?

  I'm relatively new to After Effects and text animation. What I was, I was wondering if there is a way to essentially take the effect of a wiggly selector, rotation, which applies to each individual character, and then pass? Also impressive that the expression 'loop wiggle' is, it seems to apply only to the entire text block.

  Selectors of expression work on indexes text and the expression of Dan is not adapted specifically work on text animators. It only returns a uniform value. You have to build a loop around it for each character through the clues. If you really have such a short text, it can be faster and easier for you to understand, to use only the many animations of text because there are letters and limit the influence of each in a single character...

• Wiggle of the multiple layers

  im working on a project and I want all the layers together waving as it was 1 layer...

  But if I try to put them all to shake they don't move exactly the same thing... is there a way to do this?

• I can limit movement of expression within a mask?

  Hi people,

  Can I use a wiggle expression to move an object at random, but then the movement is constrained by a mask or a limit?  I want a ball of light to squirm in a strangely shaped box...

  Lol expressions do not have access to mask data. Cold you use sampleImage() stuff, though...

• You can define wiggle at specific points in the timeline?

  Hi people,

  I made this cool tutorial on the creation of light streaks:

  https://www.YouTube.com/watch?v=w-JG1n_Yeo8

  In it, he used the wiggle expression to create random movements.  I'm trying to get a trail to follow a specific path and then move within a limited and then travel on a specific path and move within the confines of another deadline.  Imagine the light having to travel through a small tube that opens in an area where there is room to move and then through a tube again to the next area, etc..

  Someone can give me advice on how to achieve this kind of effect or do not hesitate to tell me the name of what I'm trying to achieve so that I can google it.  Thank you!

  Thanks to you two.  I'll look at both of these responses.

  Is it possible to have the AE to consider the field of composition, so that if we use the example above, the boxes and tubes, then some areas of the composition have boxes and some regions have tubes and then let the light streak move randomly within the composition and react accordingly depending on where it is in the composition?  In other words, the conditional we are talking about can be based position and not timeline based?

• Need a script to write an expression in several layers.

  I'm trying to write a script (my first) who wrote a wiggle expression in all of the layers that I select. I am well versed in the expression, but not scripts. So far, I have tried many configurations and most come back with errors. Here is my current script:

  app.project.activeItem.layer (1).property("position").expression = "wiggle (0.5,25);

  It does not give me an error message, but it does not have the expression. I have 106 layers I want regardless, slowly squirm. Any help is appreciated.

  Your script works fine for me, and it works for all selected layers:

  var mySelectedLayers = app.project.activeItem.selectedLayers;

  for (var i = 0; i)< myselectedlayers.length;="">

  .property("position").expression mySelectedLayers [i] = ' wiggle (0.5,25);

  }

• application of expression

  I've been askjing about for how an individual which effect I have seen on many music video was created.  Nobody could give me a definitive answer, I even suggested maybe that this was done by editing in premiere, others accepted is a strong possibility.  However, to keep this effect for a long period of time or try the other layer stacking would be very tedious in an editing program.

  The effect here http://youtu.be/T6j4f8cHBIM    at 0:50       or        http://www.Vevo.com/watch/Nicki-Minaj/stupid-hoe-explicit/USCMV1100087

  I was given a wiggle wiggle expression (1.50) < 50? 0: 100 which makes opacity of a layer either 0 or 100 if the wiggle value is above or below a specific number, but the result of this is random.

  I've never written my own expression and I discovered trying to verbalize the desired action and result takes language very prsice, so here is my attempt.

  I would like to order ocacity a layer by alternate, in sequential order, through a complete cycle of assigned values x times per second.

  That is to say.

  The layer opacity values A = 0, 25,50,100 read in order sequecial to frequency x

  I would like to use this expression to have layers that are stacked visible as follows:

  (The start time of each layer is the frequency and the same rate in the same expression).

  Layer opacity values A = 100, 0, 0

  Values of opacity layer B = 0, 100, 0

  Values of opacity layer C = 0, 0, 100

  With the expression applied to each layer, the Visual result in the window of the model would be to see layer A, B and C in that order x times per second.   With the expression refers to a sequence of numbers, I can choose to have 3 or 20 layers be totally, partially or invisible somehow predictable/rhythm.

  Thanks in advance

  You can do this by using a few key images and a very simple expression.

  On a layer, set a keyframe of the frame from 0 to 100% opacity. Make a keyframe of the hold, and then the next frame set opacity to zero, which should by default also. Finally on the third setting * set opacity to 100%. ALT-click on the stopwatch and add the expression loopOut(type='cycle').

  Copy your keyframes and expression of your other layers and compensate all keyframes by layer of an image of each, so on the second layer, is the first keyframe on frame a third image layer two, etc.

  * Obviously this frame depends on how many layers you want to browse. Here, we have three layers so the final image key setting the opacity to 100 is on three framework (assuming that your comp at frame zero). If you have 10 layers, it will be the frame of 10.

  Hope that helps.

• Expressions and sliders

  Hi all

  The difficulty in trying to stop my wiggle expression, so I thought I'd use a cursor to combat it.

  Agitation is applied to the position, but I have not really given any keyframes.

  Basically, my problem is whenever I use the selection with the cursor icon, just the wiggle but totally changes the position.

  My goal is to have bustle for a while, and then touch frame to go to the full amount of wiggle to zero.

  Would be nice to know how to use effectively cursors properly when I do they seem to completely cancel the expression and I can't really do work how I want - I can't seem to find tutorials that show the method for something like position, however I can for cameras a null.

  Any help would be greatly appreciated!

  Thank you

  If you wiggle and pickwhipped the cursor expression, which replaced the hustle with the expression that you have published, is that correct?

  I'm guessing you want something like this:

  amp = effect ("Slider Control") ("Slider");

  Wiggle(1,amp)

• check NULL values with expressions

  I'm having a problem with an expression that I work with.

  I'm trying to produce a dynamic graph (among other information) that seems to be controlled by a stream - stream artificial is created by a handful of sliders and a wiggle expression.

  The chart is a simple graphic line which works very well. It is created with a null value (MarkPos) that the position is controlled by Captain wiggle expression that I've mentioned before, that follows.

  This next bit is where I have problems:

  I want to score minimum or maximum, the line has reached on the chart by moving a dotted line, one for weak points and the other for the top.

  Focus only on the bottom line;

  I have the following expression associated with the line, which brings together the current position of the value null (MarkPos) and compared with the current position of the line to see if it has all moved further away down, if she has it moving the line to the new pos are lower. However, all that happens is the line following the null value.

  x = thisComp.layer("MarkPos").transform.position.valueAtTime (time) [1];

  y = transform.position.valueAtTime (time) [1];

  z = transform.position.valueAtTime(time-thisComp.frameDuration) [1];

  If (x > y) {}

  [0, x]

  } else {}

  [0, z]

  }

  After a lot of debugging, I now know the issue is with the else statement - what his weight is compensating the to the high movement frame by frame 1 - so how do you define an order of "keep your current position in y ' in this case?

  [0.1] just it back to its original position and it is not possible to just have the ' if(x>y) {[0, x]} "bit without the"else {}.

  Suggestions fo how to fix this, or a better way to do it?

  This should give you the value of y min:

  p = thisComp.layer("MarkPos").transform.position;

  minVal = 999999;

  for (f = timeToFrames (time); f > = 0; f-) {}

  minVal = Math.min (digraph, p.valueAtTime (framesToTime (f)) [1]);

  }

  [value [0], minVal]

  and this should give you the most:

  p = thisComp.layer("MarkPos").transform.position;

  maxVal = - 999999;

  for (f = timeToFrames (time); f > = 0; f-) {}

  maxVal = Math.max (maxVal, p.valueAtTime (framesToTime (f)) [1]);

  }

  [value [0], maxVal]

• Keenest wiggle?

  How would you do a wiggle expression which drastically reduces the time between values?  As Wiggle that uses an exponential interpolation in the form of values between the two? Even if the pace would be something like wiggle (1.50), it would take much less than the second 1 wiggle interval to change between values.

  Kind of like how feeds a hummingbird? It flat, flat, flat... then snap into a new position... hover, hover, hover... snap in the new position.

  Any ideas on this subject?

  (In addition, the Jagged/smooth of ancient Wiggler option is available in the form of expression?)

  No, sorry - instead:

  Ease(t, (dur-transTime)/2,(dur+transTime)/2, startVal, endVal);

  [startVal, startVal], [endVal, endVal]

  Follow these steps:

  Ease(t, (dur-transTime)/2,(dur+transTime)/2, [startVal, startVal], [endVal, endVal]);

  I have not tried, so I don't know if it does what you want.

• Using an expression for the curves effect

  Hi guys,.

  I'm looking to use the wiggle expression red to the level of the curves effect to twinkle my normal colouring to the high red video.  However, I can not activate the expression field of the curves effect in the same way I can for others.  Is it because the curves work differently, and if so, what would be the best way to get the effect I'm aiming?

  Custom controls are usually inaccessible to the expressions, because there is no foolproof way of knowing how their internal data are formatted. It's just a big black hole and only the people who program tools know what is happening inside. However, your wiggle opacity should work. If it isn't, you can also use the effect mix melted between your original and a double with the applied curves for example. Or you make a wiggle right opacity with two duplicates in the first place. Depends on what you are looking for desire, as anturally, all the different methods result in different treatment, especially in 32bpc mode...
