I’ll try to explain this the best I can. I set up my sequence to be 1920 x 1080, which should be a 16 by 9 aspect ratio. As I was editing, I noticed that some of my 1920 x 1080 clips weren’t fitting correctly into the editing view. They were letter boxed. The editing view seemed to have an aspect ratio of about 15 by 9 I’d say. I checked my sequence settings, and they were still 1920 x 1080. This was my first time using Premiere, so I didn’t really know if it was supposed to be doing this or not. Some of my 1920 x 1080 videos also fit the editing view normally. When I exported my video, I noticed that the whole video was pillar boxed. The 1920 x 1080 videos that fit the editing screen were actually stretched to do so, so they were now pillar boxed on the exported 16 by 9 video. Does anyone know why Premiere is doing this and if there’s a way to fix it?
