Publish video with transparent background
What video software do you use to publish videos with a transparent background?
I am working on a project where there will be video of a host inserted in Storyline so that the slide shows in the background. It's a common technique you see around these forums like this one MSHA46.com | Hazard Communication
I am using Premiere Elements and can use the "green screen key" to remove the background but I can't get it to publish with the transparent background. I don't think Elements has any options to publish the alpha channel. I'm thinking I need to upgrade to something like Premiere Pro or After Effects but thought I would check with the heroes to see what everybody else is using. Not exactly related to Articulate but I'm sure there are some video editing pro's out there.
