Storyline preload handling
I have a series of mp4 videos at the beginning of every slide as an intro (plays automatically ), each of which is around 1 MB big and 5 seconds long. My questions are:
1, if this video hasn't been fully loaded, will the timeline of storyline continue regardless?
2, while the user is viewing the 1 first slide, will all the videos in the following slide preload?
3, is video streaming supported in Storyline?
4, if possible, please explain in more detail how the preloading is handled in storyline.
Thanks a million.

Storyline preloads videos, it should wait for the video to preload then show the slide.
The slide should only show when eneough of the video is available to play and start progressively downloading
Storyline does not support streaming but does progressively download, you could insert a swf that streams your video or insert it as a web object from your media server
Hi Phil,
I'm currently testing to confirm this after publishing a course as html5. The slides would still show whilst the video hasn't loaded yet. It remains blank on screen and you have to wait a couple of seconds before it works, or you can toggle the timeline/seekbar to make the video to finally play. Would like to know if there is a way to make what you just have described about preloading to work?
Thanks Phil,
I will carry on some tests and get back to this post.
I am interested in this also. In Captivate there is the preloader setting to begin the course once say 20% has downloaded. Is there a similar functionality in Storyline? I have a 7MB course and my client is concerned that it is taking too long to load on slower internet connections (many of their associates are on such connections) - they want to know what their different options are for preloading the course.
Thanks!
We are also experiencing problems with the preloading part.
Is it in any way possible to customize the preloader?For example like Christina is mentioning above, in Captivate you can set preloading to x% of the course before it's start playing.
Welcome to the community, Kay!
Though there isn't currently a way to customize the preloading within Storyline, I think that would be a really cool feature request. Thanks for the input!
Hello,
I am also interested in finding out (precisely) how preloading works in storyline. I can see that the assets are in "storyline_content" folder rather than all being packaged into the story.swf, however it is not clear to me whether all of these assets are preloaded, or, if there is a percentage, or of there is a hierarchy (audio is preloaded, but video is pulled in as the person reaches the slide)?
Perhaps Storyline preloads 75%? It would be very helpful to understand this, and ultimately, allow the user to customize the preloader.
Hi James, welcome!
Here's our official, not overly-technical explanation of how preloading works in Storyline. Anything beyond that would likely need to be answered by the development team. And a custom pre-loader is a popular feature request. Thanks for the input!
Hey all... Storyline's handle of preloading works great. We have built a preloader that will display progress and let you set triggers etc based off the percentage loaded.

Hey James Kingsley,
This is damm cool, I was searching for exactly same thing. My first motive is to pre-load all GIF's included in the course at the beginning itself.
Can u plz lemme know whether this SL web object help us to pre-load all HD qualities JPG's, PNG's, and GIF included in entire course? or it only works for MP3, MP4 and SWF's?
And If I buyed this object then what type of support i can get from your team?

I'd love to know more about how Storyline handles preloading behind the scenes with Flash .swf files. I have some relatively meaty Flash interactions I have built and I have run into issues with getting them to load properly in Storyline over slow WAN connections. I have followed all the best practices for Flash publishing (AS3, Flash Player 10, 30 fps) and the movie runs great once loaded, but unfortunately, until the .swf is completely loaded, there is no visual indicator to the end-user that the .swf is getting loaded... they just stare at a blank Storyline screen.
I have build a custom preloader into my Flash .swf to display the percent loaded, but Storyline never displays it. I've tried encapsulating everything in a movieclip and just having the .swf be a 1-frame movie, but that doesn't work b/c Flash Player won't display content on the first frame until the movieclip is loaded.
I'd love to know how to best architect my Flash movies so that they cooperate with the Storyline preloading method.
Idk about SL's behind the curtains voodoo but have u tried putting your preloader on frame 1 with asset loading mechanism and reserve the presentation until slide 2?
