Variable Playback Speed

Hello Everyone!
I'm happy to share that we have released Storyline 360 version 72 (Build 3.72.29654.0).
Included in this release is a new feature where you can let learners explore at their own pace by choosing a course playback speed between 0.25x and 2x.
Now all you need to do is update Storyline 360 in your Articulate 360 desktop app on your computer. You'll find our step-by-step instructions here.
Please let us know if you have any questions by reaching out to our Support Engineers directly.
Have a great day!
Hi Michelle,
I figured out a way to control video speed using JavaScript. Please look at the attachments to see how this can be done.
FYI: This controls the speed of the video, not the timeline of the slide, which means if you use this AND have the Seek bar in the player, these will get out of sync with one another. Maybe you could "bake in" the transport controls into the video itself, and NOT use the Storyline Seek bar, to get around this issue. Still, if Articulate could use this code somehow underneath and tie the Seek bar to report video progression, then we would have something!
Hi Mark,
Your solution worked beautifully for my stand-alone videos (that I copied into your template, even when I tweaked it a bit). However, when I put them into another project, the plus and minus buttons change the playbackSpeedPC variable but not the actual playbackSpeed. I adjusted the numberOfVideos as recommended, and have double checked the script. I even imported a working version of the story into my project, but the result was the same. Any other suggestions?
Thanks!
Publish your file, open up the inspector tools in your browser ( aka the console F12 or CTRL+Shift+I ) and then you should be able to pinpoint why its not working.
