Please give the following information....
What is the project preset that you (manually) or the project (automatically) sets as the project preset.
If you do not know, please tell us what you see for Edit Menu/Project Settings/General and the readings for
Editing Mode, Timebase, Frame Rate, and Pixel Aspect Ratio.
What are the exact export choices and settings for your Timeline content....Publish+Share/ then what?
If Publish+Share/Computer, then what? And when you make the choice, do you use the default settings
or customize the preset under the Advanced Button/Video Tab of the preset?
Let us start here and then decide what next.
