Slow animation sync on iPad

I'm having a real problem with animations running behind the audio on the iPad. I use cue points to mark where various screen elements appear onscreen, and things run fine on a PC, but not iPad. This problem isn't particular to a single Storyline project file, it's ANY Storyline project.

Here are some config particulars:

  • Storyline update 5
  • Publishing includes HTML5 output, but NOT using the Articulate Mobile Player (can't use player because the content ultimately is run from an LMS that doesn't track mobile player results)
  • Running iPad with iOS 7.1 and latest Mobile Safari

I'd be grateful for ideas and suggestions. Thanks!

Patrice, I'm just getting started developing iPad content and have seen what you are talking about. My inclination is that it relates to network speed as when I test something over 3G on an iPad 2 I often get very unpredictalbe loading/playback issues. But when I test connected via WiFi they are far less apparent and often play back as expected.

Which brings up a question: is there a load sequence that Storyline uses when delivering content? For example, do graphics load before audio, do call outs load before animations, etc.? I can't seem to find a pattern as sometimes the audio will play before the screen has loaded and other times the screen will play — and move on to the next screen — before the audio even gets a chance to play.

I'm having big problems with this too. I have found it is related to the number of objects on a slide. I have had to re-develop content to break busy slides up into a number of smaller slides. Also - try reducing the document resolution down to 96dpi and turning complex tables into pictures. It wont solve all your problems but it does help!
