Is there any way to use videos with alpha channel to use in upper layers? so its backgrounds are transparent. I currently use a red background for the chroma key but it consumes a lot of resources
Are you able to provide an example of video with alpha channel? Please upload to dropbox or google drive and post here or send the link to firstname.lastname@example.org
Unfortunately ManyCam doesn’t support videos with alpha channels at the moment, so I’ve moved your post to suggestions.
