perform a Media Manager Copy and duplicate sequence and place in a new project. All media is trimmed and placed on the new volume, but the new project is not created, nor the obviously the new linked sequence. Can't make it happen on command. Happened to me a couple of times, on three tries couldn't get it to take so did a dupe and relink workaround. Has happened to some good friends who I trust and walked through the process to confirm.
Have seen it on the boards at least twice this month, so thought I'd mention it. Haven't seen it in FCP4 yet, but I can't make it happen in FCP3 either, gotta be in a crunch or something. Anybody else can confirm that?
