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

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! 

Thanks so much, Ashley!  I appreciate your help.

No problem, Peggy. I'll keep you posted on any updates, but in the meantime I hope you'll be able to use another browser or look at having those videos on your base slide. 

Hi Ashley,

I'm having this same issue, but only when viewing on a mobile device (Safari). Any idea how to fix this?

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!

Hello there,

Did any of you find the solution to this problem? I am having the same issue. I have my videos on slide layers. Some play without any flicker/flash and some flash before playing. I have tested them on LMS and on IE. I am having the same issue.

Hi Linah!

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?

If you'd like us to take a look at your project, feel free to use this secure upload link. We'll reply after reviewing the course.
