Scripting - Dive into nested sequences

[Cad81]

Hi guys, i have a problem with scripting.

I want to check some property of the clips in my active sequence and the relative nested sequences.

I know how i can loop trought the clips and property in the active sequence, but i don't know how to enter in the nested sequence and make some check and operations.

I don't know the right syntax, can you help me?

Thank you

Thought there was an easy method for getting a sequence from a projectItem, but I'm not seeing one. My approach would be to get the nodeId of the track item that you want to dive into, and then run it through a function like this to get that sequence:

function sequenceById(id) {
    var sequences = app.project.sequences;
    var len = sequences.numItems;
    for (var i = 0; i < len; i++) {
        var sequence = sequences;
        if (sequence.nodeId === id)
            return sequence;
    }
}

Hi, thank you.

I have a project with 2 sequences.

I tryied to use your code, but when  i use an alert to show the "len" var, it says "undefined".

Any idea?

Thank you!

ps: is there an object model (like after effect) for premiere (like this http://docs.aenhancers.com/introduction/objectmodel/ )?

That would be because I made a typo, it's numSequences not numItems with Sequence Collections. Here's the updated:

function sequenceById(id) {  
    var sequences = app.project.sequences;  
    var len = sequences.numSequences;  
    for (var i = 0; i < len; i++) {  
        var sequence = sequences;  
        if (sequence.projectItem.nodeId === id)  
            return sequence;  
    }  
}  
// Example Usage
var active = app.project.activeSequence.projectItem.nodeId;
sequenceById(active);

There's not an object model, but there are docs: http://ppro.aenhancers.com/

Nice, it works good, thank you!

Now i have another issue that i don't know how to solve:

with this code, i loop through all project's sequence. Instead, what i need is to dive into the nested sequence that are present only in the target sequence (i.e. the activeSequence).

Example:

in the project there are 5 nested sequences and 1 as main sequence.

The main sequence contains only 2 nested sequences. I would like to dive into only these 2 sequences and not all 5

Actually i'm using this code:

numberElements = app.project.rootItem.children.numItems;
Elements = app.project.rootItem.children;

but with this code, i get the value of the entire project. How to solve?

Again, thank you

You already have a loop to loop through all video tracks yea? Then when you're going through each clip chec if it's projectItem is a sequence with:

clip.projectItem.isSequence()

When you come across a sequence, then get the sequence with the method we discussed above. Does that answer your question?

Hi, all works fine now, thank you!

Probably i will come back for other difficulties with my little script

[Cad81]

And as i promised, i'm back

Now i have an array with media that i would like to copy in another folder on hard drive. Is possible throught scripting to copy files on disk (windows or mac)?

Thanks!

Yes this is, why don’t you make a new question for this as the topic is not related to this thread. Thanks!
