proxy for 4k footage ruined aspect ratios
**I'm very new to shooting/editing in 4k** I've shot a series of clips on a DJI mini 3 pro (in portrait mode) and out of camera the clips are 4k 3840 x 2160. So I made a custom proxy and ingest at 1280 x 720. When AME is encoding, the preview box shows my clip perfectly and everything is good. But the second the proxy hits Premiere, the aspect is squeezed in the center with black bars on the side. I've tried the native proxies as well as my own custom preset but all have the same issue. This is my first time working with a proxy so I'm either doing something wrong or Premiere is having an issue with my clips being shot portrait. Attached photos of clip and proxy settings as well as the preview monitor with proxy applied.
any help is much appreciated, I've really hit a wall
