Closed Captions Flashing

Jan 12, 2019

Got a closed captions mystery.

I've added closed captions to a video in Articulate 360. Once published, they appear at the correct times, but they flash on and off the screen with a strobe effect. 

The variable Player.Display Captions is set to true.

Any ideas? Project attached.

Hi, everyone!

I have some great news to share. We just released another update for Storyline 360. In Update 73, we’ve included important fixes and new features!

One new feature we’ve included:

Boost video accessibility by including closed captions when publishing projects as MP4 video files.

To take advantage of this update, launch the Articulate 360 desktop app on your computer, and click the Update button next to Storyline 360. You'll find our step-by-step instructions here.

Please let me know if you need additional help!

Hi there, Drake. Happy to help investigate!

To start, I published your project to Articulate Review using Storyline 360, update 3.23.17522.0. Here's the Review URL. I'm having trouble reproducing the flashing behavior in Chrome 71, so I'll need your help with these key details:

  • What Storyline 360 update are you using? To find this detail, click on the Help tab > About Storyline.
  • Did you publish the course for Web, LMS, or something else?
  • What browser(s) are you viewing the content in?

We'll figure this mystery out together!

Sorry for the delay. Been swamped with projects. All good, though, since they're in Storyline!

Version v3.23.175220

I published as a video.

Browser is Chrome.

I ended up adding the captions manually. Not afraid of grunt work, but it would've saved time if the CCs had worked without flashing. There must be something I'm missing.

Hi Bret and Drake,

Thanks for sharing those details! Our team is looking into an issue where those captions blink when you've included the trigger to show them automatically and publish to video. Closed captions aren't included in the publish to video output, so I can see why you're trying to use that trigger! 

Our team is looking into a fix for the captions, but we're also tracking a feature request to include closed captions in the MP4 output.

Hello Holly and welcome to E-Learning Heroes :)

Thanks for reaching out and letting us know that you are running into the same issue.

I do not have any information outside of what Ashley shared a month ago.

This conversation is attached to both the issue reported and the feature request so that we can update you here when we can and you should now be subscribed.

Hi, I am experiencing the same issues, would you be able to give me an update on when this is expected to be fixed?

I have 5 big business changing projects across 16  different languages I will be using caption for translation and I need to launch these within the next two months, so if it is not going to be fixed soon I will need to look at an alternative provider.

Look forward to your reply

Welcome, Olivia. Sorry to hear this bug is impacting you!

No ETA on a fix as of yet, but I promise to keep this discussion posted with any new information. Here's a glimpse into how we tackle bugs once they're reported.

While we continue to investigate this, we're happy to review your .story file to explore custom approaches. If you're able to share the .story file, please use this private upload link. We'll take a close look and will delete the file after.

Hi,

I am also having this issue. I used the auto captions trigger from the first post of this thread and I exported to video to add to an accordion in Rise ( previewing in Chrome browser). When I removed it from the accordion and imported the video from  Review 360 the flicker went away. However, I sill want to tuck it away neatly in an accordion so let me know if or when the team finds a solve.

Good Afternoon,

I am following for a solution.

I have employees that need this for accessibility and was trying to leverage Storyline to create videos with captions for them to be able to use the material. 

If there is an easy way to do this with replay 360 or another path, please let me know.

JJ Wallenius

Hello,

I'm having the same issue. I published to video and used the built-in "Player.DisplayCaptions" variable set to true so the captions will display in Windows Media Player (the default program learners will be using). When I test the video, the CCs are choppy and flashing.

We need to publish dozens of videos with CCs turned on for Windows Media Player. Is there a fix yet? 🙏

Katie Riggio

Hi JJ,

Thanks for checking in!

Closed captions won't appear in the Publish to Video output at this time, but I appreciate you trying to use that variable. 

The flashing issue is still open and we promise to update this conversation if anything changes.

In the meantime, even if you can't share the file, our Support Engineers are happy to explore any tailored possibilities.

Christiana Awojinrin

Hi Katie,

Are you able to please share some of the "tailored possibilities" so that we can implement them while waiting for a more polished solution in Storyline?  My team is publishing many "how to" videos in MP4 format and we need to employ non-strobing (!) captions in the embedded videos for accessibility. 

I have tried triggering player captions as well as setting the caption variable default to True, but the resulting captions associated with our video clips still flicker appallingly in the published MP4. 

Our current workaround is to use YouTube captions, but we would prefer to create everything within Storyline.

Kind regards,

Chrissy

Hello Christiana!

We have this logged as a bug where the closed captioning flashes when publishing to video. I don't have an update to share on this bug's progress, but when I'll report back to this discussion when I do. Our current workaround is not to use the trigger to show captions and to use rectangles with text to act as captions.

So sorry this is affecting your project! If you'd like us to look at your file, use this link to connect with a Support Engineer.

Hello everyone,

I wanted to update this discussion to share that we no longer see this issue where closed captions are blinking in a published video when using the latest version of Storyline 360, Build 3.61.27106.0.

If you or others are experiencing any additional issues using the latest update, please contact our support team directly.

Karen Embry

Just to add my work around here. I had this issue with flashing captions after uploading a video, editing captions, saving, and then clipping the last 30 seconds off of the video.

When I re-uploaded the video and clipped 30 sec off before captions were added or edited, then the strobing captions effect did not occur.
