• How can I gradually accelerate the expression of ping pong?

  Hello

  I have two key frames and I use it to repeat:

  loopOut ("pingpong")

  Is there a way I can gradually reduce the gap between the two keyframes?

  So, for example if I have a circle from the left of the screen to the right of the screen in 4 seconds. I want to speed up so that the end of the timeline, it only takes 1 second to make the move.

  Ideally if I could bind the speed of a cursor on a null object would be great!

  Any help?

  The best way to achieve this effect is to precompose the effect layer, or layer to effect and the adjustment layer, and then time-remapping the demo.

  Of the description and in my experience, there is nothing that advance composition must be interrupted in your project. If you want the background are not affected then do not include in the demo. If there is an effect, say something like a glow that bounces exhibition that you're applying for some background images, so you can just before dialing your adjustment with the LoopOut expression layer, condense the transformations, turn the demo in an adjustment layer, and then time-remapping and use the graph Editor to adjust the ramp.

  This will keep the background images play in real time but ramp to the top of the loop of pingpong.

  I hope this helps. This is a project of CS5 to show how's done it.

• Changing a value of keyframe with an expression?

  Hi all, I would like to know if its possible to change a keyframe value (lets say in the rotation) with an expression.

  I know that I can access the value with effect ("CC cylinder") .value .key (10) (4), but it is an expression of read-only. I can't assign my own value... button (4) .value = something.

  the purpose of this would be to allow someone to change the number of rotations of the ball must make by only setting the opacity of a null value to the desired number of turn (using the thisComp.layer("NbTour").transform.opacity as a starter). He would avoid mistakes like move a keyframe and by changing the animation and would also make several version easily (I have 40 versions with different number of laps...)

  Thank you very much!

  . Eric

  Eric:

  While you can't actually change the value stored in a keyframe with expressions, for all purposes, you can write an expression that gives the same result. For example, if the index of the key frame is 4, then pass the value to previous keyframe to the value specified in a slider expression control effect or the wheel (or opacity of a null value, but why bother?), for example.

  But also you can make this work without keyframes at all.

  You have to add an expression control effect Dial and add an expression like this to the rotation of the layer.

  Revols = (drag with the pickwhip to the parameter of the effect of dial).

  ease (time, 0, 5, 0, Revols * 360);

  How this expression is, as time goes by from 0 to 5 seconds (use your own timing), rotation will go 0 the number specified by the user in the dial revolutions.

• How to speed up (easeIn) rotation?

  I have a movieclip, mc_fan and when btn_Start is clicked, I want to gradually increase the rotation of mc_fan until it is rotated by 5 degrees each image and continues to run until I got on another button. Here is my code that does not quite work the way I want it. Thanks for your help!
  
  

  var speed: Number = 0;

  function fanOn()
  {
  Speed = 0;
  mc_fan.onEnterFrame = function (): Void
  {
  speed +=. 5;
  Speed = Math.min (5, speed);
  mc_fan._rotation += speed;
  };
  }
  function fanOff()
  {
  delete mc_fan.onEnterFrame;
  }
  fanStart.onRelease = function()
  {
  fanOn();
  }
  fanStop.onRelease = function()
  {
  fanOff();
  }

  Slight mods... If you have two buttons fanStart and fanStop, that should do it
  what you need.

• Clock ticking

  We have all seen the old clock rotation expression where you create a rotation of the second hand and then tie the minute hand to the rotation with an expression while he moves to 1/60th speed to simulate the minutes and seconds right?

  I am creating something similar but with a clock "Ticking" like a timex watch on the second hand so it ticks along. Tick, tick, tick, tick instead of smooth rotation. I discovered that the use of this expression related to the rotation:

  var tick = time * 6;

  Math.Floor (Tick)

  But what I want to do now is to have the tick of the minute hand (separate layer) more than 6 degrees every minute. In other words, he holds 59 seconds and then jumps 6 degrees in 1 second.

  I can't understand this part. Any ideas?

  Thank you

  Jim

  I would like to do this way:

  second hand

  Math.Floor (time) * 6

  minute hand

  Math.Floor (time/60) * 6

• Premiere Elements use a "line rate" for pan/zoom?

  Pan/zoom of Premiere Elements function has some sort of option accelerate/decelerate, selectable by the user, be integrated with the pan/zoom?

  By speed up/slow down, I mean the pan/zoom will start very slowly, then over a period of a second or two, speed up for some constant speed to move the distance defined by the user in time defined by the user and then at the end of the pan/zoom, decelerate over the last second or two at a stop.

  Makes the pan/zoom seem much more "opposite human/organic"...as to, 'robot-like' if the pan/zoom does not gently accelerate/decelerate at the beginning and at the end. "

  Thank you...

  If you are referring to Bézier curves and interpolation methods, Yes with regard to keyframes for the scale property of movement (for Zoom) and the Position property of movement (of Pan). Key tool for Zoom and Pan images can also be adjusted. Keyframing of some other properties can also be adjusted.

  First elements 13/13.1 on Windows 7 or 8.1 64-bit.

  Here is an example of creating the agricultural property keyframes.

  

  What version of Premiere Elements do you currently have and on what computer operating system is running? If you have not yet

  have elements 13/13.1 first, please rate the trial before purchase to determine the compatibility of the program with your

  computing environment and goals of video editing.

  Please let me know if I have targeted your question. For any question or need more information, feel free to ask.

• Consolidation of three lines into one

  Hello
  
  I am struggling to understand this and my Google search didn't quite led me to what I need. I found a few ideas like sys_connect_by_path but I want to convert my three rows of columns (using a line), not concatenate them. I can't quite find the right thing or get out. The code below gives me the columns I want but I can't understand how it together on a single line. When I Uncomment the line group he doesn't like it because the fields role and emp are not group expressions. I want to rotate values strings and not numbers (role).

• Physics with actionscript

  what I'm trying to do is make a circle turn and behave like a wheel... what code can I use to make a circle turn and move in the direction he then turns on the ground?

  To turn you continuously and gradually change its rotation property, and to move laterally, you change its x property.  The direction of movement x would be equivalent to the direction of rotation, the two being positive or negative.  Contiunuously happen something that you can use an ENTER_FRAME event listener assigned to the object itself.

  var dir:int = 1;  control + 1 or - 1

  var r_increment = 1;

  var x_increment = 1;

  function animateWheel(evt:Event):void {}

  Wheel.rotation += dir * r_increment;

  Wheel.x += dir * x_increment;

  }

  wheel.addEventListener (Event.ENTER_FRAME, animateWheel);

• Rotation Limit expression

  Hi all. A quick question (hopefully). Can someone advise please on a basic expression to limit the rotation of an object when it is turned manually. For example, so it can only move between 0 and 360 and no more back and forth?

  Thanks in advance or any help!

  You can use the () Math.max and Math.min () functions to keep the value in a given range.  Keep in mind that it will not limit the fundamental value of expression before, only the final value is applied to the rotation.  The object will stop turning when it reaches the upper or lower limit, but the value you provide as input will not itself forced, if that's what you hope.  If you crank well beyond a limit, so you can crank it all the way back to the usable range or reset the numeric value, as if a dimmer turned even after that the light was to its brightness max and inversion it haven't started dimming again until you have cancelled all these additional revolutions.

  This is the expression:

  minValue = 0;

  maxValue = 360;

  Math.Max (minValue, Math.min (maxValue, value))

• Construction of a wave of fishing without Express/Signal Processing Pallete

  EDIT: I forgot to attach the VI. I'll do it when I get home in 45 minutes

  Hey guys,.

  I'm working on a laboratory project that drives me crazy. We're building a VI that generates a sin, but we are not allowed to use the Express palette or sine wave functions. So we are stuck using tables and the Sin function. I have attached the VI if anyone can take a look. I would try to explain where he goes wrong, but... it's all so... One thing that I recently broke is the 'dynamic' wave is no longer scrolls to 10 Hz, but I think it's an easy fix. I hope someone can give me some pointers on what goes wrong.

  Also, I have attached a copy of explicit assignment details in case you do not want to see them.

  Display two sine waves on a single graph. Generate sine waves in a While loop that updates
  
  at 10 Hz. At each iteration, the second wave should gradually phase shift by a certain
  
  amount (degrees).
  
  Have controls for frequency, the displayed number of periods, displayed points, phase shift, and
  
  difference between display of waveforms. Make sure that the axis of the time-displays correct units. All the
  
  controls must be active and adjustable, while the program is running.
  
  Tip: You may find it useful to use a chart of waveform and the wave to build function.
  
  Do not use the range screw Express for the manipulation of signals and signal analysis. Using more arrays
  
  

  
  

• Problem - edges of digital triggering slows down during the fast rotations

  Hi all. I have problem to understand. I want to measure the pressure with two strain gages on 90 degrees (NI 9237 half bridge II) and I engine with metal plate on it with 52 teeth (gear) to measure on each tooth of the strain. For the rotation, I use NI 9401 digital input.

  I need for example 1000 samples from the first digital edge to the second. (on the metal plate). I try to start trigger. In slow speed (turn around with the hand) of the metal plate, everything is OK. But if I turn around the metal plate digital fast triggers edges slows down. During a cycle on the metal plate on the cost of slow speed me 52 digital edges 1000 sampels by edge (metal plate is with 52 teeth), but rely on fast speed on me 25 edges. This problem is sync of the digital inputs and the analog inputs. I made the example with DAqmx Vi express. I've implemented on digital imput and then count me in each tooth regardless of speed and everything is OK, but when I buid trigger of strain on the edges of quick release rotation speed slows down.

  Can someone help me with this?

  Thanks before.

  So you're collecting samples from 1000 to 10000 samples per second. Which takes 100 Ms. If your triggering edges occur more quickly than the interval of 100 ms, some of them will be missed.  If you run faster than a cycle all 5.2 seconds your gear plate with 52 teeth, some triggers will be produced before the end of the previous data collection.

  What is the fastest speed that you will not sping palte metal?

• control individual rotation of several objects with also individual wiggles

  Hello

  I'm trying to animated 2D the leaves on a tree to create the illusion of a wind blowing leaves. To get the effect I want to have each off slowly and uniquely wriggling on the rotation parameter, but if a big gust is imagined, then create a rotation together with a controller that also adds a uniform rotation in line with each leaf on top of each individual wiggle. So, indeed, that each leaf is slowly randomly turning (as with a wiggle (1.5) applied to rotation), but then I can push each leaf simultaneously with an expression such as thisComp.layer("Adjustment_Layer_1").transform.rotation

  The problem is I want both of what is happening at the same time, and right now one cancels the other.

  I am a newbie to using expressions

  You just add the values.

  mGust = this.comp.Layer ("XYZ").transform.rotation;

  mWig = wiggle (3,2);

  mGust + mWig

• 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...
