How to access caption track from script.

[LiuToki]

Hello.

In Premiere Pro, Sequence has caption track.

But i don't find how to access caption track in following document.

https://ppro-scripting.docsforadobe.dev/index.html

Do I wait to update ppro script?

[Bruce Bullis · Accepted solution]

There is no access to captions in the current ExtendScript API; such access will need to wait until PPro implements UXP extensibility.

[LiuToki]

I see.

I will wait for UXP to be available in Premiere Pro.

How far off is that? Trying to decide if a panel is the way to go for XML interchange getting our captions to show up!

Thanks!

[Bruce Bullis]

No dates for UXP API in PPro are available. Safe bet = "Not this calendar year".

PPro can import captions from .xml files, today...?

[illumn8d]

Not .xml captions but .xml project interchange. Apologies for being unclear. 😄
And yes, xml captions do currently work! (I might have been the captions guy at some time in the recent past.)

Can I load the caption xml file from script?

I use After Effects to create a template for captions (MoGRT file).

And I automate to insert captions, using load MoGRT file and replace the characters(text source) in the MoGRT.

To be precise, I put the caption string on the video track instead of the caption function.

It is possible to insert .mogrts, and change any strings which they've exposed as 'editable'.

As previously stated, there is no API around inserting or modifying actual captions.

how to do this please ?

There is no API access to caption tracks.
Such access won't be available until PPro moves to UXP-based extensibility; no dates available.

howcome this person is doing that plugin ? do they use C++ ? 
I have only the srt file subtitle importer as 'yellow layers' from my script

if (importedSRT) {

var activeSeq = app.project.activeSequence;

if (activeSeq) {

var startAtTime = 0;

var result = app.project.activeSequence.createCaptionTrack(importedSRT, startAtTime);

(- Here is the place i would like to put the .mogrt file to color the subtitle)

.

I'm not sure how they are doing it, but I can confirm that they're not doing it using any available supported API.

@Bruce Bullis,

Just to confirm my belief: there is no PR/AE function, without scripting, that will automatically populate multiple mogrts from a data source. I briefly got excited with the "Data Driven Mogrt" concept, but I now think that can only create a single instance at a time.

The feature request would be to select multiple text instances on a PR timeline, and drag a mogrt onto them. The mogrt detects the source text at uses that for that instance of the mogrt.

Well, there is this:

They are exporting srt from the PR captioning unrelated to the Plugin. Then you tell the Plugin where the srt file is, and they use Mogrts to create graphics text with animation. So basically a text file/srt feeds to text data and timing to the Plugin. As Bruce says, none of the plugin function uses PR's caption track or functions.

Clever, increasingly popular style request.
