and basically every video player. E.g. quicktime displays full
transparency in Prores4444 as black and so does FCP. You only see the
alpha if you actually have an overlay. So people building software for
looking at single video clips would probably like it to behave the
same and if that can be achieved with less CPU it definitely has
value.
