When archiving a project using File>Project Archiver>Archive Project PE11 is not saving edited clips. Instead it is saving full-length video files from the original project.
According to the manual, "Archive Project Creates a folder containing a new project file, and a new clip for each clip used in the original Quick view timeline or Expert view timeline at its edited length." In reality it creates a folder containing a new project file and full length copies of any videos used in the timeline.
For example, a project containing a single 45-minute video file edited down to 5 minutes worth of clips will be archived into a folder containing the full-length 45-minute video. My reading of the manual is that the archive folder should contain a number of clips totalling 5 minutes. I think that this would be a much more efficient use of disk space.
I've found this issue mentioned in a number of posts previously, but no solutions. Could anyone kindly suggest a way to resolve it?
That is correct.
You have the option of either archiving all of the media in your Project Media panel or only the media that is on your timeline. But archiving saves the project and the linked media files. Not trimmed versions of the raw files.
Yes, unfortunately that appears to be the case. But this behaviour doesn't match its description in the manual. This post seems to describe the same issue, and it looks like the trim feature was working in earlier versions.
