Alpha Channel tranparency for video clips

I keep revisiting this over the years, looks like 360 hasn't addressed it either. Well, at least my search of the forum turns up zero results. I'm using Finalcut Pro, exporting a short clip using the codec Apple ProRes 4444. This codec provides alpha channel encoding but I still get a black background when importing into Storyline 360 v3.35.21017.0.

I can work around this but I was sure hoping that Storyline would support alpha channels by now...

Hi George,

Thanks for contacting us to share the types of videos you are working with and that you would like to use these in Storyline 360.

Our current support is specific to FLV videos with alpha channel transparency, but we are tracking a feature request for additional support. I've added this conversation to the report so that we can share any updates with you here.

Hi George,

You likely received the email our team sent out, about what's going to happen when Adobe discontinues support for Flash, and how that impacts the Articulate tools that use Flash. You can read more about it in this article. 

In short, once Flash is no longer supported by Adobe, we'll also no longer be able to support items like the FLV videos.

Hi Ashley,
No problem with phasing out Flash, I haven’t used it in forever. I’ve switched to H264 codecs. Was just wishing Articulate had caught up with it and supported alpha channels.

Thanks for your response, good to hear from you again.
