I am trying to edit a trailer on FCP 7. I have ProRes 4444 XQ files, but they are too heavy for my Macbook Pro. I tried to convert them with Compressor, but it is a lengthy process to convert all the clips. Right now I am trying to do the conversion with the QT player. It's taking a long time as well.
Can you recommend a quicker and easier conversion process?
As for the output, ProRes 422 or even H.264 will do.
