importing transparent videos to Storyline

Mar 11, 2015


I am in need of your wisdom,

We created a drawing animation in after effects and we need to place it into our course in Storyline. We already have a background on our storyline so we made the background of our animation transparent.

But here is our dilemma, when we tried importing our animation but it shows a black background. We tried different file types such as GIF, FLV, and H.264 versions of our file but it still shows a black background instead of transparent one.

Please enlighten us in our plight. Thank you!

Hi Soren!

Have you tried other options? Most of our users seem to be utilizing the FLV option.

FLV videos with alpha channel transparency are supported in Articulate Storyline's Flash and Articulate Mobile Player (AMP) output. See this article for a comparison of Flash, HTML5, and AMP features.

There was an issue in earlier builds of Storyline where alpha channel transparency wasn't working as expected in published courses. This issue was corrected in Update 5 for Storyline.

FLV is deprecated and no longer supported by Adobe, so in After Effects 2015 you cannot export to FLV. Which leaves me in a pickle as it seems the only other export option where Transparency is supported is QuickTime Animation with RGB+ with Alpha. If I import this mov file into Storyline 2, it displays transparency as black.

What is your plan to remedy this? I mean its Adobe screwing us all over, but not having access to transparent video in Storyline 2 is messing up everything at our end and we are out of good ideas right now :(  


The workflow I am talking about is reproduced here:

I am working with AE on a mac as our Windows machines do not support AE (stupid 32 bit limitation). It seems I can pick QuickTime ProRes 4442 RGB+Alpha as the only option really. Or QuickTime Animation with RGB+Alpha.

What video formats with Alpha channel is supported and displayed correctly by Storyline 2?

Hi Soren!

I would recommend sharing your thoughts in the form of a feature request for sure.

How are you viewing your published content. Please keep in mind that Alpha Channel Transparency is not supported in HTML5 as you can see here.

I've reached out to my team to see if they have further suggestions and hopefully the community will be able to chime in as well.

Thanks, yeah I know about HTML5 and transparent video. Unfortunately. 

There is a way to make video transparency work with HTML 5

However this method is difficult to work with effectively as you need to have two videos simultaneously, one with alpha and one with RGB.  

But look at the future! When you think about it, having a video with transparency would be a nice replacement for using cartoon characters or stock photos of people pointing.

Hi Stacey, 

I'm not familiar with After Effects - but perhaps there is a way to convert those videos into FLV files. FLV files with transparency are supported in Storyline 2 as noted here. 

You'll see all the supported video file formats for Storyline 2 in this tutorial.  Can you export After Effects to any of those types?
