Export to QT mov file with alpha channel transparency
Hi there,
I’m using FCP 5.1, working on a project where I’ve used ‘ChromaKeyer’ to key out a green screen. Have gotten good results, but can’t work out how to output to a QT mov file while still retaining the transparency alpha channel.
Can anybody help…?
Thanks
Mike

I take it you want the greenscreen to be transparent…
Key the subject over the background. Remove the background. Export using a codec that supports an Alpha channel, such as the Animation Codec at Millions of Colors +
IMPORTANT: DO NOT RENDER! Rendering flattens your export and makes a composite image. Leaving it un-rendered retains transparency.

Export Quicktime movie -> then click Settings -> scroll down to custom-> use animation codec as compressor -> click advanced -> then million+ colors. I just had to do this today and it worked!
