import video with alpha background
I have shot our learning host on green screen, keyed out the background in adobe premier cc and rendered a Quicktime file that imports into all my other apps with the alpha or transparent background...
Hi Stacey,
MP4 videos don't support transparency in the same way that an FLV video does with alpha channel. Another video format that does support transparency is the .webm video format, but we don't support it in Storyline or Studio since IE, Safari and Mobile Safari also don't support it.
Hope that helps clarify.
