hi luke,
i spent some time on my computer and tried the following:
i put a camera signal via YUV into the decklink card.
i kept the decklink livekey software open while enabling the “internal key”,
manual key set to 255.
i switched to final cut pro and created text. it was possible to key the text over the camera signal, but the camerapicture lost a lot of brightness, so i guess, i still got problems with the alpha channel.
any ideas ?
we tried the same setup with a pc with adobe premiere and it worked very well.
arne.
