If you have Premiere Elements 12 Timeline that you want to export to a file with an .avi file extension, then you best go
to Expert workspace, Publish+Share/Computer/AVI and set the Presets to the appropriate setting.
Appears you have been told that already. What I suspect is being overlooked is the fact that once you get to Publish+Share/Computer/AVI
you need to scroll down (using thin scroll bar to the right of the choices) to get to AVI. If you do not, all you will see is
Adobe Flash Video, MPEG, and AVCHD.
Please let us know if any of the above in this post is the information that you sought. If not, please more details.
Thank you.
