1. Re: Set active(set focus), get *aep file name, end others noobs QS?
David Torno Jan 9, 2014 3:41 PM (in response to zipkiev)1) i find new command for AE cs6 app.activeViewer.setActive(); its set focus back to comp(to timeline with layers, after changing it to render queue when i start my script...) i need this for my task, but it not work in cs5-5.5(((, there are alternative way(any) to set focus back to comp from RQ?
I am unsure on this one.
2) how i can get name AEP file(path end others cool stuff from it) with something like app.name?
For future reference, you will get a lot of use out of the reflection object when looking for these kinds of answers (pg 221 JavaScript Tools Guide CC.pdf found in the ExtendScript folder under SDK folder). app.reflect.properties and app.reflect.methods will reveal a lot of options you have for the current object. So app.project.file will allow access to your current project file AEP info as long as the project is currently saved.
The properties are:
absoluteURI
alias
created
creator
displayName
encoding
eof
error
exists
fsName
fullName
hidden
length
lineFeed
modified
name
parent
path
readonly
relativeURI
type
Methods:
changePath(path)
close()
copy(where)
createAlias(path)
execute()
getRelativeURI(baseURI)
open(mode)
openDlg(prompt)
print(text)
read(count)
readch()
readln()
remove()
rename(name)
resolve()
saveDlg(prompt)
seek(pos)
tell()
toSource()
toString()
write(text)
writeln(text)
3) i need trim png file after exporting it from AE, now i do this with "action" in photoshop and droplet with bat file, who know a bater way?, something like sent message to photoshop directly from AE?
script on trining:
var batFile = new File ("C:\\Users\\username\\Desktop\\test.bat");
batFile.open("w","TEXT","????");
batFile.writeln("C:\\Users\\username\\Desktop\\trim_droplet.exe C:\\Users\\username\\Desktop\\ltp_face1.png\r del C:\\Users\\username\\Desktop\\test.bat");
batFile.close();
batFile.execute();
i create bat file add to it command on lunch droplet(*droplet this exe file from photoshop and it can run photoshop and start action from photoshop action menu) with my png file what i need to trim ,and delete bat file. i think this is the best way for now or.....?
Why not incorporate the resizing/cropping on the AE side. Eliminates the need for a secondary app and will speed up the process. You could create a comp template of sorts to through the png into and position it to your liking, then render out a a new png.
4) can i get version of AE(cs5 cs6 cc)?
Pg. 29 of the After-Effects-CS6-Scripting-Guide.pdf
app.version
5) i add effect to layers but, how i can remove this effect or checking if effect already exists on layers?
var myNull = myComp.layers.addNull(myComp.duration);
myNull.name="null_for_effect";
var nullControlProperty_m=myNull.Effects.addProperty("ADBE Slider Control");
nullControlProperty_m.name="effect1";
nullControlProperty_m.slider.setValue(1);
var nullControlProperty_r=myNull.Effects.addProperty("ADBE Slider Control");
nullControlProperty_r.name="effect2";
i add two sliders, but if i do same script again, i have 4 effect if again 6 effect and +++
for example i try nullControlProperty_r.remove(); and not work
You have to loop through layer effects and get the matchname or displayName that is unique (if you named the sliders specifically).
Pg. 49 of the After-Effects-CS6-Scripting-Guide.pdf
yourEffect.remove(); //PropertyBase object remove() method
6) Can i click for example on enable motion blur for all layers or graf editor or on live update buttons via script?
Pg. 56 of the After-Effects-CS6-Scripting-Guide.pdf
motion blur:
Requires a loop through all layers and then applying true/false value to layerObj.motionBlur
live update:
compItem properties include...
activeCamera
bgColor
comment
displayStartTime
draft3d
dropFrame
duration
footageMissing
frameBlending
frameDuration
frameRate
hasAudio
hasVideo
height
hideShyLayers
id
label
layers
motionBlur
motionBlurAdaptiveSampleLimit
motionBlurSamplesPerFrame
name
numLayers
parentFolder
pixelAspect
preserveNestedFrameRate
preserveNestedResolution
proxySource
renderer
renderers
resolutionFactor
selected
selectedLayers
selectedProperties
shutterAngle
shutterPhase
time
typeName
useProxy
usedIn
width
workAreaDuration
workAreaStart
Live update doesn't seem to be an option, you could possibly use app.executeCommand(app.findMenuCommandId("MenuCommandNameCaseSensitiveGoesHere")) if a menu command exists. I don't see one in AECC.

zipkiev Jan 10, 2014 3:47 PM (in response to David Torno)thx Devid for your time.., again you help me..., i try reading more AE scripting guide and new for me(JavaScript Tools Guide), but this this guides is hard to understanding in some place, because they do for more experiences users, maybe you recommended me another AE script programming books?? with more extended examples, because AE script guide have extended example not for every command.... ok better forgetting about this, but what i really interesting how i can crop image and delete all alpha in AE, i searched on this method more end more but always cant find solution, how i can detect alpha on image? and now i use method with bat file, and photoshop droplet because i can find solution...
