Exporting Green screen with alpha
Hi all,
I’ve had a request from a graphics house to give them some footage shot green screen as plain video with an alpha channel, presumably so they can comp it. I’m sure they could chroma key if needed but is there any way of getting the key channel out of X? Any codec or technique I can use to accomplish this?
Cheers,
Jason

Once you’ve applied the key to it it will automatically have an alpha channel but you will need to make sure you Share/Export as ProRes4444 in order to embed the alpha. Or you could export an Image Sequence in one of the file formats that support alpha (which I think is all of the available options bar JPEG).
