Can you have a preloader that pauses html5 while assets load in the background?

Hi everyone,

I have a 70+ slide course that has quite a bit of video. I am publishing as scaleable HTML5. I see there is a preloader option, but can this apply to html5? I want to preload media assets before the user gets too far along in the course. Is this possible? Or is this an option for swfs only?

Thanks in advance for your help, I am using Captivate2019.

Doing further research, it appears that the preloader is only for swfs. Has anyone discovered a workaround for html5?

Indeed, preloader is only functional for SWF output.

The big difference for HTML5 output (which is like a website) is that not every asset is loaded when you have started the course (contrary to SWF output). Audio and video files need to be loaded On Enter for each slide where they occur. This means that your goal would not be reached just by having a longer preloading. Improvements to long waiting times can be done by keeping video and audio short (distribute over multiple slides), by leaving a gap before the audio timeline if you use slide audio, never put heavy video/audio on the first slide, resizing video to the wanted resolution before inserting, keeping settings as low as acceptable to reach a sufficient quality.
