assign new duration to existing comp

[AltaRD]

Hi,

I am trying to set dynamic durations to my comps by passing the durations using array values.

So, I have this code:

myComp.workAreaDuration = myArray[0];

It compiles but it doesn't do anything...(yes, I have a value in the array 🙂 )

Any ideas what I am doing wrong..? Or any other ways to be able to achieve this?

Cheers!

This sets the work area duration to 5 seconds for me, as expected:

var myComp = app.project.activeItem;
var myArray = [5];
myComp.workAreaDuration = myArray[0];

I'm not sure what the issue is exactly...

Hi Dan,

I am actually creating dynamic comps and trying to assign different durations to them all inside one loop...

It might be a too adventurous idea... 🙂

I'll post the progress if I figure it out.

Thank you for checking that line for me...at least I know it's correct.

OK, but I'd expect that you'd be assigning values to myComp.duration rather than the work area duration...

I tried both...it's just not reacting at all. Tried to assign just a static value and still nothing. Next thing, I'll try a reboot :).

You are talking about scripting, and not expressions, yes?

yes a jsx that reads the values from a text file.

I also noticed that if I have a 5 sec duration and set a 10 sec with the script, it will stop with an error. I need to be able to manipulate all these durations regardless of what the duration was previously....

I think we need to see more of your script to be able to help.

OK Dan,

I got it to work like this:

var myArray = [5];

var my_renderSettings = {
"Color Depth":"32 bits per channel",
"Quality":"Best",
"Effects":"All On",
"Time Span Duration":myArray[0],
"Time Span Start":"2.0"
};

app.project.renderQueue.item(1).setSettings(my_renderSettings);

All I needed was to be able to output the rendered files at the duration of the dynamic array. 

I thought initially that it would be as simple as calling it "duration" and I guess that was where the confusion in my questions/issues started.

Thank you very much for being my chat pal 🙂 It really helped me.

Cheers,
