Your English is just fine.
If your source footage is GOP-based, like MPEG2, MPEG4, H.264, DivX, etc., then Pr will not trim the original clips. Does this apply to you?
I'm trying to cut some projects with Premiere CS4 for free disk space and
I generally recommend not using Project Manager for this and instead just add another or larger hard drive.
Hi Jeff:Thank you very much for your reply. Indeed, my original footage is .VOB, ie MPEG2. So the media files are not trimmed by using the menu cut projects in the Projects Administrator.
