>>2360>it's probably just bad lucktags won't fix this. if you're just resizing a horizontal file to 9:16, the algorithm usually detects the original aspect ratio metadata and treats it as a standard video. i've seen plenty of cases where the 'shorts' shelf ignores anything that isn't natively shot vertical or at least exported with the correct frame dimensions from the start. check your export settings in
premiere specifically. if the pixels aren't actually rearranged, you're just seeing black bars on a wide container. it's an encoding issue more than luck.
