To answer your questions directly
a. You cannot remove the Adobe watermark from exports from the Premiere Elements trial version, be it a file saved to the computer hard drive or a burn to disc product. I believe that is to what you were referring when you wrote "completed video projects" in the following
Trial Version Banner-will it go away from completed video projects if I purchase Adobe Premire?
b. You can remove the Adobe watermark from tryout project files (project.prel files) when they are opened in the purchased Premiere Elements (See Timeline Menu/Delete Rendered Files.) That is the classical answer. But, some of us have found that the Adobe watermark is automatically removed once the tryout project.prel file is opened in a purchased Premiere Elements.
With regard to what you wrote
Can I view the completed video project by Adobe using other video software on a computer without harming the video?
I am not sure what you mean by that. What is your definition of completed video project? Are you taking about an export from the project? If so that can be viewed on any player that supports the export format. You should be able to import it into another video editor that supports the video's format.
a. If you are thinking about opening a Premiere Elements project.prel file in Premiere Pro, you need to check with the specific version of Premiere Pro for its supported formats.
b. You cannot open a project.prel file created in Premiere Elements Windows in Premiere Elements Mac and vice versa.
c. You cannot open a project.prel file in non Adobe video editors.
Please review and clarify where need be. We will clarify anything written above.
Thanks for your response. I mean my finished video. Whan I save it on the
computer can I open it in another video software to view such as VLC, quick
It is with the greatest of pleasure that I respond to your email. Adobe seems to have resolved the sudden issue related to Adobe ID's and passwords not functioning in the forums and at adobe.com.
When you save your finished video from the tryout, it will have the Adobe watermark displaying in it as it plays back in your computer player, such as VLC Player and QuickTime Player.
If you are having problems in this regard, please supply more details on the export settings.
We will be watching for your further progress.
