Are transparent (alpha) videos supported?
The following format is supported for transparent videos (i.e. with an alpha channel) in the Designer:
- FLV encoded in VP6 with alpha
This format can be exported by a variety of video editing tools, such as Adobe After Effects and Adobe Premiere.
Adobe CS6 was the last Creative Suite to support this codec, for more information on how to download previous versions of apps from the Creative Cloud please see this Adobe article.
Unlike Designer, ZapWorks Studio supports MP4 with alpha. For more information on how to use transparent videos in Studio, please see the Alpha Video article.
