I see no way that Premiere Elements alone is to be involved in what you want to do unless you create prtl text titles for it. Alternately you could export your Premiere Elements Timeline to file supported by a 3rd party video editor closed captioning creator.
Premiere Pro does support closed captioning.
But, from what you wrote, none of the closed caption text that you have would be supported by Premiere Pro. Is that correct?
I started to read about the Subtitle Workshop and noted that it does allow you to preview video as you are creating the closed caption text. Is there any way for Subtitle Workshop to export video plus closed caption rather than just closed caption file?
To where do you want to deliver your video audio with closed caption....YouTube or somewhere else?
Ok, I see, problem unsolvable.
Well, I had hoped that it would be possible to import the subtitles into some freeware video editor, or doing something else. But it appears that this time I have bad luck.
Presumably you are correct that Premiere Pro can't import any of the alternatives that Subtitle Workshop can export but since I don't use Premiere Pro, I am unable to check.
As far as I can see, Subtitle Workshop can't add the subtitles to the movie. It can only create subtitles.
The distributor? A VOD service in the country where I live. If it had been Youtube I would
simply had added the subtitles in PE.
