Hi KelvinSprague​!

Sorry to hear you and your learners have run into this setback, with a Drag-and-Drop design in Storyline!

Thank you for sharing your .story file. It's possible the playback issues you've reported could be related to SkillGate LMS, or a hardware limitation of the device being used by the learners.

Regarding the LMS:

After publishing your .story file for LMS, I tested the playback with SCORM Cloud but could not observe issues or lag with the videos from the Slide. If you haven't done so already, I suggest connecting with your LMS administrator to see if any configurations can be made within the LMS environment.

Regarding Mobile Device Hardware:

A noticeable delay in playback and syncing between audio and video may point to: 

  • Hardware decoding limits on the A34 5G.
  • Videos not being preloaded or optimized for mobile streaming.
  • Possible use of higher bitrate MP4s that are too large for seamless mobile playback.

 

To address this, we recommend a tool called Handbrake that can be used to re-encode videos for more compatible mobile playback. Handbrake can help you to:

  • Target a bitrate between 1500–2500 kbps.
  • Limit resolution to 720p if possible, for better performance.
  • Set a "Web optimized" flag, to help with buffering.

 

I'll also open the floor to our community, who may be able to share additional insight and suggestions!

    The LMS provider are not too helpful, they tend to just blame the files provided. I am fully aware of Handbrake and I already utilise it to optimise all of the videos.

    I think it may well be specific to the hardware, however that doesn't help me much as they have provided this phone to a few thousand staff and it's not going to change on my say so.

      Hi KelvinSprague​!

      Thank you for following up!

      The design you've provided shares some similarities with a Storyline bug we are currently tracking. The bug is specific to Android hardware, and causes erratic playback of media from Layers on Drag-and-Drop Slides in Storyline. I'd like our senior support engineers to have a closer look at your issue, so I've opened a support case on your behalf.

      They should be following up with you via e-mail, shortly!
