Captions in the video editor

[Michalko161]

Hello,

is there already a way, or is anything planned, that applies trimming in the video editor to the linked text/vtt captions?

Greeting,

Michi

Hi Michi,
I haven't tried but I'm confident that the editor can already do that
as long as you add the subtitle as a track and not as an attachment to
the media package.

Thank you for the answer. Now my question is, how can I add the subtitles as a track. I cannot find an option to do that.

Hi Michi,

I have not tried this, but, if you wish to experiment uploading a transcript as a track. You can try the following with a manual event upload, using documentation from https://docs.opencast.org/r/9.x/admin/#configuration/admin-ui/asset-upload/.

The config file to edit is: etc/listproviders/event.upload.asset.options.properties

The following are the usual WEBVTT upload config but the type is changed to "track". 

1. Use this key to only upload transcripts with new events in the New Event source tab (only visible when adding a new event)

EVENTS.EVENTS.NEW.SOURCE.UPLOAD.CAPTIONS_WEBVTT={\

"id":"attachment_captions_webvtt",

"type": "track",\

"flavorType": "text",\

"flavorSubType": "webvtt",\

... more options such as displayOrder, etc

2. To upload the WEBVTT in the asset upload UI, visible with new and existing events, use the regular WEBVTT key. Uploading to an existing event will not be useful unless you create a workflow to trim the transcript with the mediapackage's SMIL file (if you archive your SMIL files).

EVENTS.EVENTS.NEW.UPLOAD_ASSET.OPTION.CAPTIONS_WEBVTT={\

"id":"attachment_captions_webvtt",

"type": "track",\

"flavorType": "text",\

"flavorSubType": "webvtt",\

... more options such as displayOrder, etc

Best,

Karen
