Script that changes the duration of some compositions and arrange them on timeline

[Nuria Sanchez]

For the second point i have created a script already and it is working…i only need help with the script for the first part please

Is there any reason you want to do it through a script?

According to the screenshot you’ve uploaded, you can do it by simply dragging the audio tracks from your project panel on the Create comp icon, or by right click on the tracks and click on “Create comps from selection”

The composition will be much more complex…will have maybe 20 audio files, and different other footages…so changing this stuff manually each time when i do a video like this is very time consuming….do you think that can be done with the help of a script?

[Miguel De mendoza]

Yes, it can be done by many ways. The key is to stablish a way to find the correct layer on each comp. Let’ say that you always have your song in the last layer of each comp, you can do this:

var proj = app.project;

function chageCompsDuration() {
var selectedComps = proj.selection;
if(selectedComps.length == 0) {
alert("Select one or more comps");
}

for (var i = 0; i < selectedComps.length; i++){
var curComp = selectedComps[i];
var layerIndex = curComp.layers.length; //change this for other search type
var audioLayer = curComp.layer(layerIndex);

if( audioLayer.hasAudio == false || audioLayer.hasVideo == true) {
alert("Layer" + audioLayer.name + "in Comp" + curComp.name + "is not an audio file");
}

curComp.duration = audioLayer.source.duration;
}
}

chageCompsDuration()

Then you only have to select the comps you want to change and run the script (or use the function in a onClick event, anywhere you want).

Thanks for helping me, the code seems not to work with my project…the one that i have attatched, it gives a error at line 12:

var audioLayer = curComp.layer(layerIndex);

i have selected all 3 compositions ‘Song 1’ ‘Song 2’ and ‘Song 3’ together, i have tryed with each one individual and nothing…same error..

[Miguel De mendoza]

Can you write the full error code?

[Nuria Sanchez]

Well it does not say anything…it stops and the 12 line is in red…

Anyway, i manage to do what i needed using a script, but i have to take all the comps one by one…it is not a big problem…

Thanks for trying to help me.

Try This

for example:
var audioLayer = curComp.layer(2); this means the layer number of your audio file is 2
