Closed Captions in MP4

Feb 17, 2022

I have created a training video which has audio. All my slides have closed captions included on them and these play correctly in Preview mode.

When I publish my file to Video, the closed captions do not display. Captions are on in the Player menu. I have added a Player.DisplayCaptions trigger to Slide 1 however this hasn't helped.

Any suggestions?

I don't believe Captions are actually imbedded into video files.  They are always a separate function of the video site you use to present the video.  Externally, the captions are in .SRT files that are usually uploaded to the video site as a secondary action.   This is my experience with captions and stand-alone videos.

SL has no problem with captions in videos when the course is published to SL format.

Hello Neisha, and welcome to E-Learning Heroes. 😊

Thank you for reaching out and sharing that you would like to see captions included when publishing your project to video. We are currently tracking this feature request, so I've added this conversation to the report.

I wanted to share some information about how we manage these feature requests, which may be helpful.

Being able to add closed captions to MP4 microlearning will be a huge asset to our organization. However, I have not been able to get the closed captions to appear when I view my exported MP4 using Windows Media Player, which is the one most widely provided to our employees. Is there a more detailed tutorial or perhaps a trouble-shooting guide to help me out with this new feature? The one Kelly linked above does not provide me the information I need to troubleshoot.

Hi Christina,

I'm happy to help! Using Window's default Media player, you can enable the captions in your published video by clicking the 'Languages and subtitles' button and selecting the corresponding subtitle file, as shown below:

If the issue persists, kindly share what Windows Media Player version you are using. The legacy version does not support subtitles.
