Re: Question about color / colorpicker / eyedroppe...

Your script can temporarily apply a color control to the layer, apply a sampleImage() expression to the control, harvest the result (post-effect) with your script, and delete the control, Dan

This will write it to the JavaScript console: $.writeln(padre.item(i).name + " ---> " + _banda[0]) Dan

This gives me the upper left corner of my floating dialog: alert(uiPal.frameBounds.left + ", " + uiPal.frameBounds.top); Dan

From the AE Script Editor (File > Scripts > Open Script Editor): Help > JavaScript Tools Guide There's a whole chapter on UI. Dan

Say you do this: var myMask = app.project.activeItem.selectedLayers[0].Masks.property(1).property(1) .valueAtTime(0,false); myMask will be a shape object with 4 attributes: myMask.vertices gives you an array of 2D points, in layer space, one for each vertex. myMask,inTangents gives you an array of incoming tangent points, relative to each vertex. myMask.outTangets gives you an array of outgoing tanget points, relative to each vertex. myMask.closed is true if the shape is closed Dan

This Position expression should work. Adjust mult to set the sensitivity (how much it moves in response to the audio) and minVal to set how much it moves when there is no audio. mult = 10; minVal = 5; L = thisComp.layer("Audio Amplitude"); aud = L.effect("Both Channels")("Slider"); accum = 0; for (f = timeToFrames(inPoint); f <= timeToFrames(); f++){ accum += Math.max(aud.valueAtTime(framesToTime(f)),minVal); } value + [0,0,accum*mult] If you have separated the Camera's dimensions, change the last line to this to make it suitable for Z Position: value + accum*mult Dan

It should work like this: var myString = "XxXxXx"; alert(myString.toLowerCase()); // should give "xxxxxx" Dan

Dan Ebberts · ‎Oct 27, 2011

You probably want the JavaScript indexOf() string method. It returns -1 if there's no match. Assuming variable i is a string, it would be like this: if ( layer.mask(j).name.indexOf(i) >= 0) {do something} Dan

Dan Ebberts · ‎Oct 24, 2011

I doubt that there's an existing script that does exactly what you want. The good news is that it sounds pretty straight forward and not a bad scipt to tackle as a first script if you have some time. Basically, you need to: Prompt the user for the language code. Go through all the affected comps looking for the layers that start with the existing/default language code. Do a replaceSource() on those layers, replacing their sources with the appropriate language precomp. Dan

I'm sure you figured out that there's a typo in the expression I posted. I left out the closing quote on "Slider". Dan

Dan Ebberts · ‎Oct 22, 2011

I'm not sure what you're doing with the slider, but I think this is all you need for the mouth: aud = thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider); y = linear(aud,0,36,1492,1547); [1001.5,y] If you already have the mouth positioned at [1001.5,1492], you could just do this: aud = thisComp.layer("Audio Amplitude").effect("Both Channels")("Slider); y = linear(aud,0,36,0,55); value + [0,y] Dan

Once you have the path, you can manipulate it using JavaScript's string operations, but to get it to point at a new folder, you need to use ExtendScript's Folder() constructor. You should check out the JavaScript Tools guide, which you can get to from the ExtendScript editor's Help menu. Dan

Dan Ebberts · ‎Oct 20, 2011

The complete path would be: app.project.file.path + "/" + app.project.file.name (assuming the project has been saved). I'm not sure about the python stuff, but I suspect you can't do it. Please report back if you find out otherwise. Dan

Dan Ebberts · ‎Oct 18, 2011

Hmmm... do you have any breakpoints defined? Dan

Dan Ebberts · ‎Oct 15, 2011

Ah yes, I forgot about that little twist. After you apply the first preset, you probably need to do this: myLayer1.selected = false; myLayer2.selected = true; Then apply the preset to Layer 2. Dan

Dan Ebberts · ‎Oct 15, 2011

Something like this: var myLayer1 = myComp.layer("Layer 1"); var myLayer2 = myLayer1.duplicate(); var myPreset1 = File(path to preset 1); var myPreset2 = File(path to preset 2); myLayer1.applyPreset(myPreset1); myLayer2.applyPreset(myPreset2); Dan

Dan Ebberts · ‎Oct 07, 2011

It looks like you have the blending mode part right. Is the other part of your question how to set a layer's opacity value? That would be like this: theLayer.property("Opacity").setValue(41); Dan

Dan Ebberts · ‎Oct 04, 2011

How about just using sliders and wiggle(). For example, setting a slider to 10.5 and applying this: wiggle(5,2.5) will give you a range from 8 to 13. Then just link your readouts to the sliders. Dan

Dan Ebberts · ‎Oct 03, 2011

Try this: myArray = [1,1.3,1.4,1.3,1.6,1.2,1.2,1.1,1,1.4,1.5,1.2]; idx = Math.min(Math.floor(time),11); value*myArray[idx] Dan

Assuming you have all the pieces parented together in two chains where the first layer in each chain has the anchor point in the middle, the others have the anchor point where they attach to their parent, and one chain is parented to the the other, the two pieces that attach to the main parent get this: -parent.rotation*2; everybody else gets this: -parent.rotation Dan

Dan Ebberts · ‎Sep 24, 2011

I don't think scripting has access to that. Dan

Dan Ebberts · ‎Sep 22, 2011

You have to create a file object for your preset and then use applyPreset(), like this: var thePreset = File("C:/Program Files/Adobe/Adobe After Effects CS5.5/Support Files/Presets/Behaviors/wigglerama.ffx"); theLayer.applyPreset(thePreset); Dan

Dan Ebberts · ‎Sep 22, 2011

It should be like this: theLayer.blendingMode = BlendingMode.SOFT_LIGHT; Dan

Dan Ebberts · ‎Sep 22, 2011

Does that mean that when they get to the edge of the original circle the scale is zero? If so, assuming your slider goes from 0 to 100 to get the layers from the center to the edge of the circle, the scale expression would look like this: s = thisComp.layer("controls").effect("Slider Control")("Slider"); [100,100] - [s,s] Dan

Dan Ebberts · ‎Sep 22, 2011

Yes.

Dan Ebberts · ‎Sep 22, 2011

I think you have to create a new output module template with the color depth you want. The script can then apply that by name. Dan

Dan Ebberts · ‎Sep 19, 2011

You can use $.evalFile() to run a script from within a script. Dan

Dan Ebberts · ‎Aug 26, 2011

The for loop is part of core JavaScript. If you're at all serious about this stuff, you need a good JavaScript reference. I like David Flanagan's "JavaScript the Definitive Guide" (it's the most worn book in my library), but there a lot of good references out there. Dan

Dan Ebberts · ‎Aug 26, 2011

This is a simple example that samples every frame: accum = 0; for (i = 0; i <= timeToFrames(); i++){ accum += valueAtTime(framesToTime(i))*thisComp.frameDuration; } accum You could have it sample more often to improve the accuracy, but this is probably close enough for most applications. Dan

Dan Ebberts · ‎Aug 14, 2011

You want it to start at the layer's in point, is that correct? If so, this should work: beginCount = 0; stopCount = 100; beginTime = inPoint; countDur = 4; // count for 4 seconds "" + Math.round(linear(time,beginTime,beginTime + countDur,beginCount,stopCount)) + "%" Dan
