The only way to Copy and Paste between Projects is with a ClipBoard Extender, like ClipMate.
Now, you can use the WAB (Work Area Bar) on the Timeline in Project A, to Export/Share an AV file, of just the area that you wish to reuse, and Import taht into Project B.
I read your reply and the links you provided me with.
Basically what you are suggesting is to export a section of the AV into an MPEG file, and than import it back into the new video. Is this correct?
If so, how do I get individual components of the timeline? Say I have a mix of video, audio, picture and titles all in one section of the video that cannot be interrupted or separated. By doing what you suggest I will end up with one file. Importing this file back I doubt that I will restore all the individual sections but it will be a unique AV section. Am I right or not?
If yes, then this solution you suggest is not usefull because I need to export data that needs to be edited back. How to do so?
It this is not possible, hoping to not be unpolite PrE sucks at this. It is a common need to utilize old sections of a video if needed or if I work on a project and after hours of work I realize I have to start from beginning because the project setting is not correct I will loose those hours of work.
If you wish to move the elements in the Timeline, separate, then you will need a ClipBoard Extender app., like ClipMate, to Copy the desired Clips, Titles, etc., then Open a different Project move the CTI (Current Time Indicator) to the desired location, and Paste. You cannot do that, without a Clipboard Extender.
If you are using the WAB (Work Area Bar) to Export/Share a portion of the Timeline, you will NOT get the separate elements, i.e. Clips, Titles, etc., but an AV file, with those written to the new, output file. Editing that output file will be tougher, as the elements are now all combined, and all Handles in Clips, etc., will not be included. If one goes that route, then MPEG would not be my choice, and I would go with one of the suggestions in this article: http://forums.adobe.com/message/4556586#4556586
Remember, with that output method, the Clips (Audio & Video) will NOT have any Handles, and Titles will be burned in.
From your comments, I think that you want the ClipMate (or similar) workflow.
I would caution you about the use of ClipMate for Premiere Elements 11. Versions 8.0/8.0.1, 9.0/9.0.1, and 10 worked great for me and others.
But Premiere Elements 11 and versions of Premiere Elements earlier than 8.0/8.0.1 have problems in the copy/paste of audio and/or transitions between Premiere Elements projects. At this time, I know of no other copy/paste software to do the job that ClipMate did with the versions where it worked successfully in all respects.
I can offer you a detailed how to for ClipMate and Premiere Elements (all versions mentioned) if necessary. All the wrinkles worked out except for those in the versions mentioned.
