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.
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.
