Videos Flash/Flicker Before Playing in LMS and on Articulate 360 Review

Hi there! I have created three content pages that launch MP4s (created in Vyond, formerly GoAnimate). The videos play as expected when I launch them locally via Storyline 360. However, when I review the course in Articulate 360 review or on my client's LMS, they flash/flicker before they play. Any ideas what I can do to resolve this issue? I tried adding a trigger with a one-second delay, as some of the other video troubleshooting posts suggested; however, it didn't fix my issue (I have since removed it). 

I have attached my .story file. My browser is Edge, but the videos play fine as standalone MP4s. Here's a sample:

Hi Peggy,

Thanks for sharing the file. I took a look and published it to Articulate 360 and you'll view it here. 

I also took a quick recording of what I saw using Peek so that I could demonstrate it. I didn't experience any flashing in Chrome as you'll see, but I did see it in Edge only the first time a video loaded. 

I tested your video files on a new slide, and it seems that the flash is only occurring when the video files are on a slide layer vs. the base slide. I'll share this example with my team, and will let you know here as soon as I have any more info!

Hey, Nadia! Tell me a little more about this project.

  • What version of Storyline are you using? Are you on the latest update?
  • Is the video a MP4 file?
  • Is that file on the base layer or on a slide layer?

If you're able to share the slide with our team for testing, that'd be even better! You can send it privately to our support team here. They'll delete it as soon as they're done troubleshooting.

Hi Alyssa,

Thanks for getting back to me.

  • I'm using the most current update of SL360.
  • The videos are mp4s (they were mov files converted to mp4 upon import into SL).
  • All videos are on base layers
  • I was using Safari on an iphone X, my colleague experienced the same behavior on Chrome via an iphone 6s.

I also submitted a case (#01789005) and linked back to this thread.

Hi there, Nadia. Thanks for this handy information!

I see you and my teammate, Christopher, are knee-deep in troubleshooting to get to the root of the flash on mobile issue. Thanks for working with us, and you're in great hands with our skilled Support team.

We're here if there's anything else we can help answer!

Sorry, you're running into this snag! We're happy to troubleshoot with you.

Let's start here:

  • Which version of Storyline are you using?
  • Have you published the course for HTML5 only?
  • Do the videos work as expected when using a different browser like Chrome?

Hi there,

I am encountering a similar issue.

I have an mp4 video on the base layer, and it glitches within the first 2 seconds of playing even in preview mode. It also glitches the same way when I publish it to Review360...

I wondered if a solution had been found since it resembles issues stated above. 

I have many slides with mp4's embedded the same way as this one so I cannot figure out why this one is having this issue.

I am running the latest update of storyline

Thank you

Hello Stephanie, and welcome to E-Learning Heroes! ⭐️

Happy you reached out! A couple of questions to start:

  • Does the video work as expected if you view it in a different browser, or is it having these glitches in all browsers?
  • Was this particular video created differently than the ones that are working fine?

If you can share the video or your project with us, we'd be happy to test it out. Feel free to use this private link, and we'll reach out after testing!
