Landscape vs Portrait in Premiere Pro CC V12.1
I have two videos taken with my cellphone moments apart of the same subject - the Nantucket Lightship from the window of Boston's ICA in the rain. The camera was held in the same "landscape" orientation and the file properties in Windows Explorer shows Frame Width 1920, Frame Height 1080 on both. In the thumbnail in Windows it shows them both the same, with a horizontal horizon, They both play correctly in both the Applian and Windows media players.
BUT - when I import them into Premiere Pro one of them comes out in "landscape" mode and the other one comes out sideways, in "portrait" mode. And the thumbnail in the Premiere Pro media browser also shows one in portrait and the other in landscape, even the the thumbnail in Windows explorer shows them both correctly in landscape.
What is Premiere Pro keying on to think one of these is in "portrait" mode and how do I fix it?
Thanks in advance!
