In February of 2016, Brightcove released its newest video player Version 5. This new Brightcove Player allows publishers to deliver 100% HTML5 to their audience. Among other benefits, this means that there is complete independence from Flash. In order to take advantage of this newer, faster technology, Brightcove requires WebVTT format for all new integrations. Brightcove is also discontinuing support for other file formats and is encouraging clients to move to the WebVTT format before the end of 2017.
Dotsub supports the new Brightcove Player version 5 and provides the required WebVTT format for all new integrations. We will help you convert to the WebVTT format. In order to convert the existing captions into the new format, you will need to supply Dotsub with the new Brightcove OAuth credentials from the Brightcove account administration panel. When you are ready contact us via email at support@doub.com.
On the Dotsub side, we will republish to Brightcove all the links to your old caption and subtitle files in WebVTT format. How long will it take? It’s usually a matter of a few minutes, but the length of time will depend on many factors such as volume and web traffic. The set-up is completely automated and does not require any human intervention.
If you have any question or concerns, please email support@dotsub.com.
