Now that Hype has prores export capability, it would be great to create alpha channels.
This could be used in the blackmagic design ATEM TV Studio Switcher for keyed effects.
It really doesn’t matter if this doesn’t work for html output; they wouldn’t use that feature.
This would be one way to instantly have a whole new set of potential users.
Now if you wanted to get real fancy you could have a direct export feature like they have
done with a photoshop plugin.
Or just sell the company to Blackmagic Design and let them do it.
