I'm trying to export a film in 4k proress422 that has a 3840 x 2304 aspect ratio, 5:3 resolution. Adobe randomly displayed the film in the timeline as 16:9, but is still listed as 3840x2304. The black bars on the sides are missing and if I scale down the clips they just become smaller 16:9 clips. If I change the aspect ratio to 16:9 then the picture becomes slightly bigger and cuts off the areas around the border of the clips. When I export it, the film is in the 16:9 ratio even though the settings are still listed as 3840x2304. QuickTime also changed all my previous 5:3 sample videos into this 16:9 look, but has 3840x2304 as its aspect ratio in its settings. I don't know what the hell is going on where it even changed the aspect ratios look with clips and videos I exported a long time ago when this glitch randomly happened yesterday. I was wondering if anyone else has dealt with this problem.
