Closed captions not appearing when the screen has an audio file only

Feb 05, 2018

Hi there ...

I can get closed captions working with a video (and they do so beautifully!), but am failing to have any success when the screen simply has an audio track.

I can see the captions button and use a trigger to make sure that is turned on to show CC but nothing appears. The captions do appear in the caption editor, of course.

I have tried exporting the captions and importing them, but that doesn't work for me.

I have also used the Text-to-speech facility (also superb!) and ticked the 'Create closed Captions' box, but again, no captions appear.

I'm on the latest update (v3.12.14647.0)

Am I missing a trick?

Hi there, Martin.  You aren't missing a trick - we've got an issue documented where closed captions are not appearing in Preview when the captions are for an audio-only slide, and when it's the first slide.  The good news is your captions should appear as expected in your published output.

I've tagged this discussion to be updated with news of a fix!

Great timing! I also came across this issue today.

I have noticed that if I return to a previous slide, then the closed captions don't replay or get stuck on the first caption.

It's fine if I use the seekbar to move back and forth within a slide. It's fine if I view slides out of order too.

The same thing happened to me. I have a course with 50-60 slides and only on few of them I have this issue. The other day everything worked just fine - I opened my storyline file today just to update some things and noticed this issue.

Hey everybody. I'm excited to let you know that we just released update 13 for Storyline 360! It includes new features and fixes - check them all out here.

One of the fixes addresses an issue where closed captions were not always showing in Preview or in some browsers with HTML5 output.

Here’s how you can update Storyline 360 to take advantage of everything the latest release has to offer. Let me know how you make out!

To add an refinement to this, I ran in to this first slide caption issue this week (fully updated Storyline 360). I have found that if the audio track starts playing at the very beginning of the timeline (0.0 secs) of the first slide, they don't show with HTML5. If the audio tracks begins slightly after that (.25 secs) the captions will show with HTML5.

I am having difficulty with the closed captions option for a new project.  I am using SL 360.  I have the closed caption option selected in the Player box.   I have all of my verbiage in the notes section of the project.  I have engaged the Text to Speech feature.  But when I go to preview the project or publish it, there is not CC option on the screen.  What am I missing?  Thanks in advance for any assistance.

Thank you

The key to making this work seems to be the Generate Closed Captions option in the top right corner of the Insert|Audio|Text to Speech window.

I tested as follows:

I have the Captions option selected in the Player.

If I then insert Text to Speech audio but do not also click the option in the top right hand corner to Generate Closed Captions, then no CC icon appears. Even if I add a custom button and toggle the Player.DisplayCaptions variable, nothing happens - no captions are displayed.

However, if I insert Text to Speech audio and click the option in the top right hand corner to Generate Closed Captions, then the CC icon appears and the Closed Captions work. My own toggle button will also work (but it's unnecessary, because the CC icon appears as well and does the same thing!)

However, if I switch off the Captions option in the Player, then no CC icon appears and I need my custom button to toggle!
