Premiere Elements 14 and what computer operating system involved?
Nonetheless...I see no way for 14 to offer you an export file with Timeline menu markers that will allow your viewer to navigate the playback of the file.
Premiere Elements Timeline menu markers function in the menu applied to burn to exports, not export to file.
Premiere Elements 12/12.1 is the last version to offer webDVD in the Publish+Share area. With this choice, you essentially get a flash file with menus (markers et al), The webDVD is usually played back with the computer default browser. I have done this with Firefox.
I did come across the following which might be of interest, but it is not Premiere Elements based
Later today I will give what you want to do a workout with some maneuvers and to double check. My first impression is what you want to do cannot be done with Premiere Elements.
To be continued....
I looked in a few possibilities and all ended at the same conclusion for me that Premiere Elements 14 is not offering an export with menus that the viewer can playback with navigation.
But, what might be interesting to explore, uploading the video to a place like Vimeo and adding chapter markers there?
Thank you for looking into this for me
