alpha background not rendering (black)

Hello,

I recently bought the 24 broadcast news complete package for premiere pro. most of it works fine (the essential graphics) but the transition video clips (.mov) are not rendering as alpha layers. they should be an alpha layer with a transaction in the middle. I’m seeing a black background where the alpha should be. It’s the same in after effects too.

I tried to key out the black but it doesn’t work as it seems to not recognise the black. Like it knows it’s alpha but it’s displaying as black.

How can i fix this ?

Ask the Author of the work.

Use After Effects then Extract & Refine Hard Edge.
