Hi team, I want to confirm whether Premiere Pro supports fully programmatic SRT subtitle generation for an active video sequenceSpecifically, Can SRT files be generated automatically (without having the user to export anything for the video sequence) using UXP APIs / CEPs? If CEP allows it but UXP does not, is SRT export or any caption-export API planned for UXP in the near future? Is there any official workflow/documentation I can follow for generating SRT from a timeline or caption track entirely through scripting? Thanks

Hi team,

I want to confirm whether Premiere Pro supports fully programmatic SRT subtitle generation for an active video sequence
Specifically,

Can SRT files be generated automatically (without having the user to export anything for the video sequence) using UXP APIs / CEPs?
If CEP allows it but UXP does not, is SRT export or any caption-export API planned for UXP in the near future?
Is there any official workflow/documentation I can follow for generating SRT from a timeline or caption track entirely through scripting?

Thanks

Correct answer Bruce Bullis

Yes, PPro can programmatically generate SRT files, using output presets (.epr files) that specify the desired output.
At least one media (audio or video) file is also required, though your panel/plugin is welcome to delete that file, as desired.

There is no documentation specific to caption tracks; the same encodeSequence() call is used for media and caption output (as described above).

@Bruce Bullis,

This is all my understanding, but to be clear:

There is no access to File -> Export -> Captions or from the Text panel/captions tab Export -> SRT type processes?

I assume the sequence must already include a caption track and captions.

@jay_0706,

When you said "fully programmatic SRT subtitle generation," I wondered if you intended to generate the subtitles as well as creating the SRT file.

Correct.

Yes, to successfully export captions, a caption track must be present. 🙂
