From the EDIT page, select clip(s).
From the File menu select “media management”
In media management dialog select: Clips, Video Format Quicktime, Codec h264, and limit data rate at 4000

Select your media.
Press command M to export media.
Select Quicktime and Pro-Res Proxy. The file will be about 40% of the original size.
