I’ve only done about 45 sequences this way in the past couple of weeks (under 4.5), so I’m pretty sure of my settings, but here goes:
COPY media referenced by duplicated items
Include render files: YES
Include master clips outside selection: NO
Delete unused media from duplicated items: YES
Use handles: NO
Include affiliate clips outside selection: NO
(Media file names don’t really matter here, but I’m basing them on CLIP names)
Duplicate selected items and place into a new project: YES
Thanks for the reply!
