Storyline closed captions not displaying when project is published as video

Feb 01, 2022

Hello. I have a Storyline project that has a few slides on which I want closed captions to display. I've added the Player.DisplayCaptions trigger on each of those slides, to start the captions when the timeline for the slides starts.  I also have captions selected in the player (classic player). It all works beautifully in preview. However, when I publish to video/mp4 format, the captions don't display.  Can anyone help me with this?  Is it not possible to have closed captions display when publishing to video?  We're using Chrome browser. Thanks.

  • Are you using the latest version of Storyline 360? Currently, we're on build 3.73.30119.0.

I'd like to take a look at your file to investigate what's going on. You can upload it here or share it privately in a support case. We'll delete it from our systems once troubleshooting is complete.

Hello Dana, 

Yes, that is the correct behavior. The closed captions will appear as a .vtt file when you publish your course to video. See this article for more information: 

To view your video with closed captions, enable the caption option in your media player's settings. You may need to manually select the .vtt file for some media players. 

Let me know if you have any questions!
