Hi, I' m a user of sozi many months ago.
I started a project in youtube for a music theory chanel in spanish, using lilypond + Inkscape and Sozi in many videos. In animation dedicated software I learn to use a alpha chanel for transparencies, Blender and Natron are capable in this way, but in Sozi it's impossible at moment, or not? In Blender I use the option PNG for rendering, this format is capable to save alpha chanel content and I suposse, it's possible for ffmpeg export in this format? Why Sozi can't export in this format (a png sequence is in many cases generated before converting in a mp4 or avi file)? It's possible add an option for sozi-to-video for save in a png sequences trough ffmpeg or before this process the video?
