Is there a way to copy some or all of the workof one projedt ( clips, transitions and effects) into another project. I would especially like to use the same rolling credits in all my video's. I've tried copy/paste and Get Media from a file but I get "file format not supported" when I try to import a .prel (project)
Try Exporting your file as a .AVI file first. This way when you need it again all you have to do is grab it. I also use this technic when I have really big productions. I just finished a 5 camera dance recital. I would edit 2 to 3 dances then save as an .AVI. Once I have them all completed I built a single file. This helps with the file size. Good Luck!
There is a also a Clipboard "extender," ClipMate, that will allow one to Copy/Paste from one Project to another. I have not used it, but many have and few have any issues.
The Export to DV-AVI method is the main one. The only thing to think about is that you will want either a perfectly tight edit, before the Export, or a very loose edit (I'd go so far as to add 02 sec. of Black Video between un-Trimmed Clips), as you will not want to, say replace a Transition, as you would have to Trim even more of your Clips to create the necessary Handles.
