I'm new at Premiere. I just want to do a simple task, combine an audio track with a single square image, and then export/publish it to Youtube. But when I do this, the image doesn't fully fill the youtube display. The image is scaled so that the Youtube video playback controls don't overlay it. I get a black border around it. I have right clicked and selected "Scale to Frame", as otherwise Premier's display similarly shows a large black border. When I select that, Premier then scales the image it so that it full fills the height of the display. But this has no effect on what is uploaded to Youtube. I thought what I see on the Premier display would be duplicated when I selected to Publish to Video. But obviously not.
I must be doing it too simple. Maybe I need to save the project? Or define the image size? I was assuming what I see on the Premier display would be duplicated on Youtube publish, but obviously not. Thanks for helping a clueless person. - Mark
